MARIN RADAR EQUIPMENT INSTRUCTION MANUAL PRECAUTIONS BEFORE OPERATION Cautions for high voltage High voltages from hundreds volts to tens of thousands volts are to be applied to the electronic equipment such radio and radar devices. You do not face any danger during normal operation, but sufficient cares are required for maintenance, inspection and adjustment of their internal components. (Maintenance, check-up and adjustment of the inside of the equipment are prohibited except by maintenance specialists.) High voltages of tens of thousands volts are so dangerous as to bring an instantaneous death from electric shock, but even voltages of hundred volts may sometimes lead to a death from electric shock. To prevent such an accident, make it a rule to turn off the power switch, discharge capacitors with a wire surely earthed on an end make sure that internal parts are no longer charged before you touch any parts inside these devices. At the time, wearing dry cotton gloves ensures you further to prevent such danger. It is also a necessary caution to put one of your hands in the pocket and not to use your both hands at the same time. It is also important to select a stable foothold always to prevent additional injuries once you were shocked by electricity. If you were injured from electric shock, disinfect the burn sufficiently and get it taken care of promptly. What to do in case of electric shock When finding a victim of electric shock, turn off the power source and earth the circuit immediately. If it is impossible to turn off the circuit, move the victim away promptly using insulators such as dry wood plate and cloth without touching the victim directly. In case of electric shock, breathing may stop suddenly if current flows to the respiration center in the brain. If the shock is not so strong, artificial respiration may recover breathing. When shocked by electricity, the victim will come to look very bad with weak pulse or without beating, resulting in unconsciousness and rigidity. In this case, it is necessary to perform an emergency measure immediately. FIRST-AID TREATMENTS First-aid treatments As far as the victim of electric shock is not in dangerous condition, do not move him and practice artificial respiration on him immediately. Once started, it should be continued rhythmically.
(1) Do not touch the victim confusedly as a result of the accident, but the rescuer may also get an electric shock.
(2) Turn off the power source calmly and move the victim away quietly from the electric line.
(3) Call a physician or ambulance immediately or ask someone to call a doctor.
(4) Lay the victim on this back and loosen his necktie, clothes, belt, etc.
(5) a. Examine the victims pulse.
(6) Open the victims mouth and take out artificial teeth, cigarette or chewing gum if any. Keep his mouth open, stretch his tongue and insert a towel or the like in his mouth to prevent the tongue from suffocating. (If it is hard to open his mouth due to set teeth, open it with a screwdriver and insert a towel in this mouth.) b. Examine his heartbeat bringing your ear close to his heart. c. Examine his breathing bringing the back of your hand or your face close to his face. d. Check the size of the pupils of his eyes.
(7) Then, wipe his mouth so that foaming mucus does not accumulate inside. When pulse is beating but breathing has stopped
(Mouth-to-mouth respiration) Fig. 1
(1) Tilt the victims head back as far as this face looks back. (A pillow may be inserted his neck.)
(2) Push his jaw upward to open his throat wide (to spread his airway).
(3) Pinch the victims nostrils and take a deep breath, block his mouth completely with yours and blow into his mouth strongly. Take a deep breath again and blow into his mouth. Continue this 10 to 15 times a minutes (blocking his nostrils).
(4) Carefully watch that he has recovered his natural breathing and atop practicing artificial respiration. If it is difficult to open the victims mouth, insert a rubber or vinyl tube into one of his nostrils and blow into it blocking the other nostril and his mouth completely.
(6) When the victim recovers consciousness, he may try to stand up suddenly, but let him lie calmly and serve him with a cup of hot coffee or tea and keep him warm and quiet. (Never give him alcoholic drinks.)
(5) Method of mouth-to-mouth respiration by raising head
(1) Raise the victims head. Support his forehead with one of your hand and his neck with the other hand. j When you tilt his head backward, the victim, in most cases, opens his mouth to the air. This makes mouth-to mouth respiration easy.
(2) Cover his mouth as widely as possible with yours and press your cheek against his nose k or, pinch his nostrils with your fingers to prevent air from leaking. l
(3) Blow into his lungs. Continue blowing into his mouth until his breast swells. Blow into his mouth as quickly as possible for the first 10 times. Fig. 1 Mouth-to mouth respiration When both pulse and breathing have stopped Perform the (Cardiac massage) Fig. 2 and (Mouth-to-mouth respiration) Fig. 1 When no pulse has come not to be felt, his pupils are open and no heartbeat is heard, cardiac arrest is supposed to have occurred and artificial respiration must be performed.
(1) Place your both hands, one hand on the other, on the lower one third area of his breastbone and compress his breast with your elbows applying your weight on his breast so that it is dented about 2cm (Repeat compressing his breast 50 times or so a minutes). (Cardiac massage) In case of one rescuer, Repeat cardiac massages about 15 times and blow into his mouth 2 times quickly, and repeat this combination. In case of two rescuers, One person repeats cardiac massages 15 times while the other person blow into his mouth twice, and they shall repeat this combination. (Perform the cardiac massage and mouth-to-mouth respiration)
(3) Examine his pupils and his pulse sometimes. When the both have returned to normal, stop the artificial respiration, serve him with a cup of hot coffee or tea and keep him warm and calm while watching him carefully. Commit the victim to a medical specialist depending on his condition. (Never give him alcoholic drinks.) To let him recover from the mental shock, it is necessary for persons concerned to understand his situations and the necessary treatment.

PRECAUTIONS DANGER Never conduct inspection or repair work of equipment components. Inspection or repair work by uncertified personnel may result in fire hazard or electrocution. For inspection and repair work of equipment components, consult with our branch office, branch shop, sales office, or our distributor in your district. When conducting maintenance, make sure to turn the main power off. Failure to comply may result in electrocution. Turn off the main power before cleaning the equipment. Especially when a rectifier is used, make sure to turn it off since voltage is still outputted from the rectifier even after the indicator and the radar are turned off. Failure to comply may result in equipment failure, or death or serious injury due to electric shock. When conducting maintenance work on the antenna, make sure to turn its main power off. Failure to comply may result in electrocution or injuries.
- iii -
DANGER Make sure to turn off the antenna operation switch. Failure to comply may result in injuries caused by physical contact with the rotating antenna. WARNING Never directly touch the internal components of the antenna, receiver/transceiver, or indicator. Direct contact with these high-voltage components may cause electrocution. For maintenance, inspection, or adjustment of equipment components, consult with our branch office, branch shop, sales office, or our distributor in your district. To contact our sales department, branch offices, branch shops, and sales offices:
Please refer to the "Office List" at the end of the document. Do not get close to the radiant section of the antenna. It is a rotating part, and it may cause injuries if it suddenly starts rotating and consequently hits the body. It is recommended that the radiant section be installed at a high place such as on the roof of the wheelhouse, on the flying bridge, on the trestle, or on the radar mast so that no one can get close to it. When any work must be done on the antenna, make sure to turn the antenna switch off.
- iv -
WARNING About radiation from the antenna:
Never stare at the antenna from a distance closer than that specified below for each type of antenna when it is emitting radiation. Being within the specified distance from the center of the front face of the antenna may cause radiation exposure which could result in injuries
(especially of the eyes). NKE-2102/2252 (radiodensity: 10 W/m2): 0.6 m NKE-1075 (radiodensity: 10 W/m2): 1.1 m NKE-1075 (radiodensity: 100 W/m2): 25 cm Make sure to install the antenna at a place higher than human height. Direct exposure to electromagnetic waves at close range will have adverse effects on the human body. Direct exposure to electromagnetic waves at close range will have adverse effects on the human body. When it is necessary to get close to the antenna for maintenance or inspection purposes, make sure to turn the indicator power switch to "OFF" or "STBY."
Direct exposure to electromagnetic waves at close range will have adverse effects on the human body. When conducting maintenance work, make sure to turn off the power and unplug the power connector J1 of the processor so that the power supply to the equipment is completely cut off. Some equipment components can carry electrical current even after the power switch is turned off, and conducting maintenance work without unplugging the power connector may result in electrocution, equipment failure, or accidents.

WARNING When cleaning the display screen, do not wipe it too strongly with a dry cloth. Also, do not use gasoline or thinner to clean the screen. Failure to comply will result in damage to the screen surface. Do not change MBS Level/Area unless absolutely necessary. Incorrect adjustment will result in deletion of nearby target images and thus collisions may occur resulting in death or serious injuries. When disposing of used lithium batteries, be sure to insulate the batteries by attaching a piece of adhesive tape on the and terminals. Failure to comply may cause heat generation, explosion, or fire when the batteries get shorted out. CAUTION Use the radar only as a navigation aid. The final navigation decision must always be made by the operator him/herself. Making the final navigation decision based only on the radar display may cause accidents such as collisions or running aground.
- vi -
CAUTION Use ATA only as a navigation aid. The final navigation decision must always be made by the operator him/herself. Making the final navigation decision based only on ATA information may cause accidents. ARPA information such as vector, target numerical data, and alarms may contain some errors. Also, targets that are not detected by the radar cannot be acquired or tracked. Making the final navigation decision based only on the radar display may cause accidents such as collisions or running aground. A malfunction may occur if the power in the ship is instantaneously interrupted during operation of the radar. In this case, the power should be turned on again. When using the [AUTO SEA] function, never set the suppression level too high canceling out all image noises from the sea surface at close range. Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited. When using the [AUTO SEA] function, make sure to choose the most appropriate image noise suppression level. When using the [AUTO RAIN] function, never set the suppression level too high canceling out all image noises from the rain or snow at close range. Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited. When using the [AUTO RAIN] function, make sure to choose the most appropriate image noise suppression level.
- vii -
CAUTION When setting a guard zone, make sure to properly adjust gain, sea-surface reflection suppression level, and rain/snow reflection suppression level so that the optimal target images are always on the radar screen. The guard zone alarm will not be activated for targets undetected by the radar, and it may result in accidents such as collisions. The simulation function is used exclusively for deciding whether or not ATA/ARPA is properly operating. Therefore, never use this function unless you wish to check ATA/ARPA operations. Note especially that, if this function is used during actual navigation, simulated targets are displayed and may become confused with other actual targets. Therefore, never use this function during actual navigation. Optimal values have been set for VD LEVEL and CONSTANT; therefore, never change their values unless absolutely necessary. Failure to comply may result in accidents that would lower ARPA performance. Make sure to shut off the main power before replacing parts. Failure to comply may result in electrocution or equipment failure. When replacing magnetrons, make sure to shut off the main power and let the equipment stand for more than 5 minutes to discharge the high-voltage circuit. Failure to comply may result in electrocution.
- viii -
CAUTION Make sure to take off your watch when your hand must get close to the magnetron. Failure to comply may result in damage to the watch since the magnetron is a strong magnet. Make sure that two or more staff member work together when replacing the LCD. If only one person attempts to replace the LCD, he/she may drop it and become injured. Do not directly touch the inverter circuit of the LCD display with a bare hand since high voltage temporarily remains in the circuit even after the main power is shut off. Failure to comply may result in electrocution. Any adjustments must be made by specialized service personnel. Incorrect settings may result in unstable operation. Do not make any adjustments during navigation. Failure to comply may result in adverse effects on the radar function which may lead to accidents or equipment failure. Any adjustments must be made by specialized service personnel. Failure to comply may result in accidents or equipment failure. Do not make any adjustments during navigation. Failure to comply may result in adverse effects on the radar function which may lead to accidents or equipment failure.
- ix -
CAUTION Do not change the quantization level settings unless absolutely necessary. If set at an inappropriate value, the acquisition or tracking function of ARPA deteriorates, and this may lead to accidents.

The main functions include:
sensitivity adjustment sea clutter and rain/snow clutter suppression interference reflector bearing and range measurement using a cursor, fixed/variable range markers, and electronic bearing own track display NAV line and marker displays TM (True Motion) presentation self-diagnostic facilities radar performance monitoring (Performance Monitor) ARPA functions (manual/automatic, target acquisition and tracking, vector and trail displays and alarm displays) (option) simple plotter functions (marker and line display, destination/route setting) (option) 4-unit switchover (Inter switch) function (option) 1 - 1 1.2 FEATURES 1 Realization of Large, Easy-to-see Screen with High Resolution The 18.1-inch color LCD with high resolution of 1280 1024 pixels can display radar images of 250 mm or more in diameter. Even short-range targets can also be displayed as high-resolution images. Target Detection by Latest Signal Processing Technology The system employs the latest digital signal processing technology to eliminate undesired clutter from the radar video signals that are obtained from the receiver with a wide dynamic range, thus improving the target detection. Advanced Technology Based ARPA/ATA Functions (Option) The ARPA target acquisition and tracking performance is enhanced by the use of the fastest DSP and tracking algorithm. So stable operation in target tracking under clutter is ensured. Acquisition and tracking of 100 targets for ARPA, 30 targets for ATA. Hazardous conditions are represented by shapes and colors of symbols as well as sounds. Trial maneuvering functions provided. (ARPA) Trails of up to 20 target ships can be stored with a maximum of 1,500 points for each of them, and displayed distinguished by using seven different colors. Overlay of Radar Images, Coastlines, and Own Ship's Track As well as operator-created NAV lines, the data of coastlines, objects such as buoys, and own ship's tracks/ARPA trails, which is stored on the memory card can be superimpose-displayed with radar images and radar trails in all display modes including the head-up mode. Use of the optional plotter function enables the creation/display of marks and lines and the settings of waypoints/courses. Easy Operation with GUI All the radar functions can be easily controlled by simply using the trackball and two switches to operate the buttons shown on the radar display. 1 - 2 Improved Day/Night Mode Two types of background colors are available in each Day/Night mode (total 4 background colors). Each background color can be reproduced to be suited for the users operating environment by simple key operation. The radar echoes and a variety of graphics can also be represented in different colors, ensuring easy-to-see displays. Compact Design and Low Power Consumption Since an LCD has been implemented as the display device, the weight of the display is greatly reduced and the power consumption is lowered in comparison with the conventional radar equipment. Self-diagnostic Program Incorporated The Self-diagnostic program always monitors all the functions of the system. If any function deteriorates, an alarm message will appear on the radar display and an alarm sounds at the same time. Even when the system is operating, the functionality test can be carried out. (except on some functions) Performance Monitor (Option) The radar performance (transmitted output power and receiving sensitivity) can appear on the radar display.
* The PM unit (NJU-63/64) is needed separately. Easy Interswitch Operation (Option) If an interswitch unit (option) is connected, up to four JMA-5300 radars can be switched over by performing simple operation.
* An interswitch (NQA-3141-4) is needed separately.

* Button 1 on the radar display on page 2-7 is also available to switch the range. 315 3.4.4 Tune 3.4 BASIC OPERATIONS This system tunes the transmitting frequency and receiving frequency under automatic control, so it does not need any tuning by hand 3.4.5 Control Sensitivity [GAIN/PL]
Procedures 1 Control noise on the radar display by turning the [GAIN/PL] control until targets can be easily observed. Turning [GAIN/PL] control clockwise increases sensitivity. Turning [GAIN/PL] control counterclockwise decreases sensitivity. Turning the [GAIN/PL] control clockwise increases receiving sensitivity and extends the radar observation range. If the sensitivity is too high, the receiver noise increases reducing the contrast between the targets and the background video. As a result, the targets become obscure on the radar display. To observe densely crowded targets or short-range targets, turn the [GAIN/PL] control counterclockwise to reduce the sensitivity so that the targets are easy to observe. However, be careful not to overlook important small targets. 3 316 3.4.6 Suppress Sea Clutter [AUTO-SEA]
Caution When using the [AUTO SEA] function, never set the suppression level too high canceling out all image noises from the sea surface at close range. Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited. When using the [AUTO SEA] function, make sure to choose the most appropriate image noise suppression level. Procedures 1 Control the sea clutter returns on the radar display by turning the
[AUTO-SEA] control until targets can be easily observed. Turning [AUTO-SEA] control clockwise suppresses sea clutter returns. Turning [AUTO-SEA] control counterclockwise intensifies sea clutter returns. The sea clutter suppression function suppresses sea clutter returns by decreasing the receiving sensitivity on a short range. Turning the [AUTO-SEA] control clockwise heightens the effect of sea clutter suppression. However, be careful that excessive suppression causes low signal-strength targets such as buoys and boats to disappear from the radar display. Before sea clutter returns can be suppressed in accordance with their intensity, the automatic sea clutter suppression mode must be selected by pressing the [AUTO-SEA] control. Use this automatic mode when sea clutter returns vary in direction. To change back to the manual mode, press the [AUTO-SEA] control again. Note: The AUTO SEA (automatic sea clutter suppression) mode and the AUTO RAIN (automatic rain/snow clutter suppression) mode cannot be used at the same time. Using AUTO SEA (automatic sea clutter suppression function) Procedures 1 Press the [AUTO-SEA] control. AUTO SEA is selected, and SEA AUTO is indicated at the lower left of the radar display. If AUTO SEA is selected, rotating the AUTO RAIN control and AUTO SEA control can make fine adjustments manually. 317 3.4 BASIC OPERATIONS Note: When AUTO SEA is selected, AUTO RAIN is switched to the manual mode. AUTO SEA and AUTO RAIN cannot be selected at the same time. Cancellation 1 Press the [AUTO-SEA] control. AUTO SEA is deselected, SEA AUTO at the lower left of the radar display changes to SEA MAN , and AUTO SEA is cancelled.
* Button 14 on the radar display on page 2-7 is also available to switch AUTO/MANUAL. 3 318 3.4.7 Suppress Rain/Snow Clutter [AUTO-RAIN]
Caution When using the [AUTO RAIN] function, never set the suppression level too high canceling out all image noises from the rain or snow at the close range. Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited. When using the [AUTO RAIN] function, make sure to choose the most appropriate image noise suppression level. Procedures 1 Control the rain/snow clutter returns on the radar display by turning the
[AUTO-RAIN] control until targets can be easily observed. Turning [AUTO-RAIN] control clockwise suppresses rain/snow clutter returns. Turning [AUTO-RAIN] control counterclockwise intensifies rain/snow clutter returns. When the [AUTO-RAIN] control is turned clockwise, the rain/snow clutter suppression function suppresses rain/snow clutter returns and gets targets hidden by rain/snow clutter returns to appear on the radar display. However, be careful that excessive suppression may cause small targets to be overlooked. Since the rain/snow clutter suppression function also has the effect of suppressing sea clutter, the suppression efficiency improves when the
[AUTO-RAIN] control is used with the [AUTO-SEA] control. In general, turn the
[AUTO-RAIN] control fully to the left. Before rain/snow clutter returns can be suppressed in accordance with their intensity, the automatic rain/snow clutter suppression mode must be selected by pressing the
[AUTO-RAIN] control. To change back to the manual mode, press the [AUTO-RAIN] control again. Note: The AUTO SEA (automatic sea clutter suppression) mode and the AUTO RAIN (automatic rain/snow clutter suppression) mode cannot be used at the same time. Using AUTO RAIN (automatic rain/snow clutter suppression function):
Procedures 1 Press the [AUTO-RAIN] control. AUTO RAIN is selected, and RAIN AUTO is indicated at the lower left of the radar display. Rotating the AUTO RAIN control and AUTO SEA control can make fine adjustments manually. 319 3.4 BASIC OPERATIONS Note: When AUTO RAIN is selected, AUTO SEA is switched to the manual mode. AUTO SEA and AUTO RAIN cannot be selected at the same time. Cancellation 1 Press the [AUTO-RAIN] control. AUTO RAIN is deselected, RAIN AUTO at the lower left of the radar display changes to RAIN MAN , and AUTO RAIN is cancelled.

If the currently indicated bar is extremely shorter than when initially checked, the transmitter system needs to be inspected by the service engineer. 392 d n o i t a u n e t t A e v i t a l e R Check Procedure Read the value A of the current bar length. Referring to the Calibration Curve I, obtain the relative attenuation d (B) for the initial bar length B shown on the INFORMATION LABEL. Referring to the Calibration Curve I, obtain the relative attenuation d (A) for the value A. The result of d (A) - d (B) indicates the current attenuation of transmitted power compared with the initially specified value. When d (A) - d (B) indicates attenuation of 10 dB or more (due to the end of magnetrons life), the transmitter system needs to be inspected by the service engineer. Calibration Curve I Date and time of initial setting Initial bar length Maximum range of PM pattern Measuring accuracy Current Bar Length l Figure 1 393 3.9 OPERATE PERFORMANCE MONITOR
(Example) When the initial bar length B = 8 and the current bar length A = 6, the relative attenuation is obtained as d (B) = 3.5 dB and d (A) = 7 dB according to the Calibration Curve I. Thus, d
(A) - d (B) = 3.5 dB. This proves that the current attenuation of transmitted power is about 3.5 dB.

3 COAST:
Use this mode to monitor a relatively short range, for example, bays and coasts where many boats and ships are running. (Importance is attached to resolution.) DEEPSEA: Use this mode to monitor a relatively long range, for example, the open sea.
(Importance is attached to long-range sensitivity.) FISHNET: Use this mode to detect small targets such as fishnets of round haul netters hidden by sea clutter returns. (Importance is attached to sea clutter suppression, and sensitivity to moving targets lowers.) Use this mode when many rain/snow clutter returns or sea clutter returns are detected in stormy weather. (Importance is attached to rain/snow clutter and sea clutter suppression, and sensitivity slightly lowers.) Use this mode when only a few rain/snow clutter returns or sea clutter returns are detected. Use this mode when sea clutter is not strong but rain/snow clutter is strong.
(Importance is attached to rain/snow clutter suppression, and sensitivity slightly lowers.) Use this mode to detect tens of seabirds at low altitude during coastal navigation or hundreds of seabirds at high altitude during ocean navigation. Use this mode to detect small targets at relatively long distance in the open sea. Use this mode to detect small targets like radio buoys in areas outside the sea clutter area. (This mode displays targets of which detection probability is low.)

[Page 1] [5] Auto SEA/RAIN (Auto STC/FTC) Detects unwanted waves such as rain/snow clutter and sea clutter and automatically suppresses them. When the sea state or weather changes, this function automatically performs suppression processing in accordance with the situation. unwanted waves. Suppression processing is not full automatic, and requires the operator to control the afterimages of To control the afterimage of sea clutter, use the [SEA] control. To control the afterimage of rain/snow clutter, use the [RAIN] control. In areas where the density of unwanted waves is low, unwanted waves may remain being judged as targets. Thus, use the automatic clutter suppression mode together with the video process mode. Characteristics of the automatic clutter suppression function:
OFF:
Disables the automatic clutter suppression function. Select OFF when rain/snow clutter and sea clutter are not strong or when the ship is in a bay. AUTO SEA: Automatically detects the strength of sea clutter, and performs the most suitable sea clutter suppression processing. Even when the strength of sea clutter varies depending on the wind direction, AUTO SEA performs the most suitable suppression processing. Land like islands can be displayed naturally. Since rain clouds outside sea clutter areas are recognized as land, there is no effect of suppressing rain/snow clutter. AUTO RAIN: Along with AUTO SEA, AUTO RAIN automatically detects the strength of rain/snow clutter, and performs the most suitable rain/snow clutter suppression processing. When rain clouds are scattered about, AUTO RAIN performs rain/snow clutter suppression processing for only the rain-cloud areas. Since land is recognized as rain clouds, land videos become obscure.

[Page 5] [1] Gain Offset Corrects sensitivity while the function mode is called. Since the displayed noise level varies depending on the combination of the video process mode and the interference rejection level, sensitivity needs fine adjustment for always obtaining the highest level. The sensitivity correction function saves the correction value set by the sensitivity control in each function mode, so it can obtain the highest sensitivity without the sensitivity control being operated when the function mode is changed. To set high sensitivity, set a value on the + side. To set low sensitivity, set a value on the - side. When the radar interference rejection level is increased, the noise level is lowered. Thus, set a sensitivity correction value to the + side. When the video process mode 3SCAN CORR, 4SCAN CORR, or 5SCAN CORR is used, the noise level is lowered. Thus, set a sensitivity correction value to the + side. When the video process mode REMAIN or PEAK HOLD is used, noise is hard to disappear. Thus, set a sensitivity correction value to the - side. 3

[I] Resolution between adjacent targets and swapping during automatic tracking Depending on the particular distance and echo size, resolution between adjacent targets during automatic tracking usually ranges somewhere between 0.03 to 0.05 nm. If multiple targets approach each other, resolution will become about 0.03 nm and this may cause the system to regard them as one target and thus to swap them or lose part of them. Such swapping or less of targets may also occur if the picture of the target being tracked is affected by rain/snow clutter returns or sea clutter returns or moves very close to land.
[II] Intensity of echoes and the tracking function The intensity of echoes and the tracking function have a correlationship, and thus the target will be lost if no echoes are detected during six scans in succession. If a lost target exists, therefore, radar gain must be increased to support detection of the target. If, however, radar gain is increased too significantly, sea clutter returns or other noise may be erroneously detected and tracked as a target, and resultingly, a false alarm may be issued.
[III] Adverse effects of error sources on automatic tracking To execute accurate tracking, it becomes necessary first to appropriately adjust the [GAIN], [SEA] and [RAIN] controls of the radar so that the target to be acquired and tracked id clearly displayed on the radar display. Inappropriate settings of these controls reduce the reliability/accuracy of automatic tracking. 51 5.1 PREPARATION This section explains the features of EPA/ATA/ARPA and AIS functions, and the initial setting for using each function. The four plotting functions below are available with this radar equipment. An optional device is necessary for using each of the ATA, ARPA, and AIS functions. EPA (Electronic Plotting Aid) function The EPA function calculates the course and speed of a target from the positions of the target that have been entered manually at specified intervals. The EPA function is available when the ATA and ARPA options are not installed. ATA (Automatic Tracking Aid) function The ATA function calculates the course and speed of a target by automatically tracking the targets move. The ATA function enables automatic acquisition of targets by using the guard zone function. The ATA function is available when the ATA option is installed.
(This function cannot be used with the ARPA option.) 5 ARPA (Automatic Radar Plotting Aid) function The ARPA function calculates the course and speed of a target by automatically tracking the targets move. The ARPA function enables automatic acquisition of targets by using the guard zone function. The ARPA function also enables the simulation of the maneuvering method for avoiding collision by using the trial maneuvering function. The ARPA function is available when the ARPA option is installed. The ARPA function provides higher-level functions than the ATA function.
(This function cannot be used with the ATA option.) AIS (Automatic Identification System) function The AIS function shows the targets information on the radar display, using other ships information sent out from the AIS unit. The AIS function is available when the optional AIS interface is installed. 52 Attention l The menu display is changed to ATA or ARPA according to option provided in this radar equipment. Where the ARPA option is provided, the ARPA Setting is displayed in the menu. Also where the ATA option is provided, the ATA Setting is displayed in the menu. This manual basically displays using ATA. 53 5.1 PREPARATION 5.1.1 Collision Avoidance Problems of Collision Avoidance in Navigation Marine collision avoidance is one of the problems that have been recognized from of old. Now, it will be described briefly who the collision avoidance is positioned among the navigational aid problems. The navigation pattern of all mobile craft constitutes a system with some closed loops regardless of the media through which the mobile craft travels, whether air, water, the boundary between air and water, or space. This pattern consists of two closed loops in principle, one of which is a collision with another mobile craft and the other is a loop of finding a right and safe way to reach a predeterminate destination. Fig. 5-1 shows the conceptual diagram of navigation pattern by MR. E.W. Anderson. The closed loop of collision avoidance is shown on the left side and the closed loop of finding a right course on the right side. 5 Fig. 5-1 Navigation Pattern Marine Accidents and Collisions Among marine accidents, collision accidents have been highlighted as the tonnages and speeds of ships become higher along with the increase in traffic at sea. If a tanker carrying dangerous articles such as crude oil collides with any other vessel, then not only the vessels involved with the accident but other vessels in the vicinity, port facilities, inhabitants in the coastal area as well as marine resources may also suffer immeasurable damages and troubles. Collision accidents have a high percentage of the marine accidents that have occurred in recent years. To cope with these problems, any effective measures are needed and some equipment to achieve collision avoidance requirements have been developed at rapid strides. 54 Basic Concept of Collision Avoidance There are two aspects in collision avoidance: collision prediction and avoidance. Collision prediction is to predict that two or more vessels will happen to occupy the same point at the same time, while collision avoidance is to maneuver vessels not to occupy the same point at the same time. In practical operation of vessels, a spot of collision has to be deemed to be a single point but a closed zone. This closed zone is conceptually defined as a CPA (Closest Point of Approach). In collision prediction, the time to be taken until a ship reaches the CPA is defined as a TCPA (Time to CPA). Fig. 5-2 shows a diagram caked Collision Triangle. Fig. 5-2 Collision Triangle Relative Vector and True Vector From two points of view, collision prediction and avoidance, it is necessary to obtain the relative vector of other ship for prediction and the true vector of other ship for collision avoidance in order to grasp other ships aspect. The relationship between the relative vector and true vector is shown in Fig. 5-3 Both rough CPA and TCPA can be obtained easily from the relative speed vector of other ship. This method has an advantage that the risks of collision with all other ships within the radar range can be seen at a glance. On the other hand, the course and speed of other ship can easily be obtained from its true speed vector, enabling other ships aspect to be seen at a glance. Thus, the aspects of other ships (transverse, outsail, parallel run, reverse run, etc. ) as described in the Act of Prevention of Collision at Sea can be readily grasped. If there is a risk of collision with other ship, the operator can determine which rule to be applied and how to operate own ship. 55 5.1 PREPARATION 5 Fig. 5-3 Relative Vector and True vector Radar and Collision Avoidance Radar is still playing an important roll for collision prevention and positioning. A plotter is used to further enhance the radar functionality. The plotter is capable of plotting other positions of other ships in 3 to 6 minute intervals to monitor their movement. The plots of other ships represent their tracks relative to own ship, and it is shown whether there is a risk of collision, namely CPA and TCPA can be obtained. This method using a plotter is fairly effective, but the number of target ship, which are manually plotted, is limited and it takes several minutes to measure those. 56 5.1.2 Definitions of Symbols Types and Definitions of EPA, ATA, and ARPA Symbols Vector/Symbol Definition Remarks Safe target Alarm characters (CPA/TCPA) appear and an alarm sounds. The vector and symbol blinks with red lamp. When numeric data is displayed, the target symbol is changed into .

* The setting method is the same as the method of a guard zone. For the creation method of sector alarm, refer to 3-67P and Chapter 3.5.20 for the creation method of sector alarm. 512 5.2 EPA OPERATION This section explains how to use the EPA function. The EPA function is available when the ATA and ARPA options are not installed. The EPA function stores/displays vectors as the courses and speeds of target ships. The data of up to 10 target ships (plot/ID numbers 0-9) can be specified. The EPA function calculates CPA/TCPA, and issues an alarm. The data of plotted target ships is erased from memory when the power is turned off. The EPA function does not display any past plot data.
* The same setting procedure for ATA/ARPA applies to the following settings. See the ATA/ARPA setting procedure. 1. Vector Time 2. Past Position 3. CPA Limit 4. TCPA Limit 5. CPA Ring Vectors are displayed when a target is plotted twice. A course and speed are calculated from the two plotting positions, and the plotted target moves in the course at the speed. The plot can be modified. The plot number (target ID number) is not displayed while Display ID Number is set to OFF. 5.2.1 Plotting Targets Procedures to [9]. 1 Move the cross cursor mark onto the target on the radar display, and press the [ACQ] key to start the first plotting. 2 Enter the plot number (target ID number), pressing the numeric key(s) [0]
3 Press [ENT] to finish the first plotting. The acquisition symbol and plot number will be displayed at the plotting position. 4 When 30 seconds to 15 minutes has passed after the first acquisition, move the cross cursor mark onto the current target position, and take steps 1 to 3 to perform the second plotting. When finishing the second plotting, the system clears the symbol and plot number that were displayed at the end of the first plotting, and displays the symbol (vector) and plot number at the second plotting position. The plotted target (symbol and plot/ID number) moves in a specified course at a specified speed. The course and speed are calculated from the two plotting positions. At this time, the CPA and TCPA at positions where the plotted target moves are calculated, and an alarm is issued when the plotted target goes into the guard zone. 513 5.2 EPA OPERATION 5.2.2 Modifying Plotted Target Data The system modifies specified plotted target data. It clears the specified data, and displays the plotted target immediately before it moves to the clear position until re-acquiring a target. Procedures 1 Press the [ACQ] key. 2 Enter the plot number (target ID number) for modification, pressing the numeric key(s) [0] to [9]. 3 Press the [CLR] key. The previously updated status will be displayed. M is also displayed beside the mark, indicating that modification is in progress. 4 Move the cross cursor mark to the modification position to re-acquire a target. At this time, specify the plot number you entered in step 2.
([ACQ], [0]-[9], [ENT]) 5 5.2.3 Canceling Plotted Target Data The system cancels the display of specified plotted target data. Once plotted target data is canceled, it cannot be restored any more. Procedures 1 Press the [ACQ] key. 2 Enter the plot number for cancellation, pressing the numeric key(s) [0] to
[9]. 3 Press the [TGT CNCL] key. The plotted target data of the specified plot number will be canceled. Canceling all plotted targets Procedures 1 Hold down the [TGT CNCL] key for 5 seconds or more.

EXIT ON ON 5 Note: When this function turns off and CPA/TCPA alarm occurs, alarm does not sound. Take care for maneuvering the ship. 516 5.3 ATA/ARPA OPERATION This section explains how to use the ATA and ARPA functions. Each function is available only when the ATA or ARPA option is installed. The functions automatically track a target, and store/display vectors as the course and speed. They calculate CPA and TCPA, and issue an alarm. The basic operations of ATA and ARPA are the same, but available functions are different. The ATA function can track up to 30 ships; the ARPA function can track up to 100 ships. Both functions set a guard zone for automatic acquisition. The ARPA function permits the use of the trial maneuvering function (TRIAL). (The ATA does not.) When the power is turned off or the transmit/standby mode is activated, tracking data is erased from memory. 5.3.1 Acquiring Target Target acquisition can be performed on two modes, AUTO and MANUAL, and both modes can be used at the same time. Automatic Acquisition [AUTO]
Attention l If untracked targets intrude into the guard zone in the conditions that maximum number of targets is under tracking, the targets acquired automatically will be cancelled in the order of lower levels of danger. 1 Press the [GZ ALARM] key. Automatic acquisition will be started. The mark and target ID number are put to an acquired target, and they move together with the target. The vectors are displayed within one minute. 2 Press the [GZ ALARM] key again. Automatic acquisition will be turned off, and the guard zone disappears from the radar display. However, automatically acquired ships are continuously tracked. For the guard zone to be called by using the [GZ ALARM] key, refer to Section 5.1.6 Setting Automatic Acquisition Key Assignment.
* The guard zone can be called by using buttons and shown in the radar display on page 2-7. 49 50 517 Procedures 5.3 ATA/ARPA OPERATION Manual Acquisition [MANUAL]
Attention l If more targets are acquired manually in the condition that the maximum number of targets are under tracking, the targets under tracking will be cancelled in the order of lower level of danger in order to track the manually acquired targets. 5 1 Move the cross cursor mark onto the target to be acquired, and press the
[ACQ] key. The target will be acquired. The initial acquisition mark and target ID number are put to the acquired target, and the vectors are displayed within one minute. Target manually captured. The initial capture symbol is displayed. Target that has intruded the zone for 1 min. The capture symbol and vector are displayed. When using only the manual acquisition mode alone, press the [GZ ALARM] key to turn off the automatic acquisition mode. Procedures Use of Automatic and Manual Acquisition Modes [ACQ AUTO] / [ACQ MANUAL]
Use the manual acquisition mode while the automatic acquisition mode is on. Manually acquire the target to which particular attention should be paid, and get the other targets automatically acquired. If a new target appears exceeding the maximum number of targets, the manually acquired target is displayed even in the background until it gets out of the display. However, automatically acquired targets are canceled starting far distance from own ship. 518 5.3.2 Canceling Unwanted Targets Unwanted targets can be canceled one by one in the following cases:
Tracking is no longer necessary for targets with which vectors/symbols are displayed after being acquired and tracked. The number of vectors on the radar display needs to be reduced for easy observation. When targets are to be re-acquired from the beginning, all the current vectors can also be canceled. Canceling targets one by one Procedures 1 Move the cross cursor mark onto the target to be canceled. 2 Press the [TGT CNCL] key. The targets vectors and symbols will disappear, and only the radar video remains. Canceling all targets collectively Procedures 1 Hold down the [TGT CNCL] key. The vectors and symbols of all the targets will disappear, and only the radar videos remain. Note: When all the targets have been canceled, the system stops tracking them. Thus, you need to re-acquire targets in manual or automatic acquisition mode. Do not cancel all the targets unless otherwise required. 519 5.3 ATA/ARPA OPERATION 5.3.3 Displaying Target ID No. (Target Number Display) A target ID number is a value displayed beside the acquisition symbol when a target is acquired. ID numbers are assigned to targets in acquisition order. When the ATA function is used, ID numbers 1 to 30 are automatically assigned. When the ARPA function is used, ID numbers 1 to 100 are automatically assigned. Each target is identified by the assigned ID number until it is lost or its acquisition is canceled. Procedures 1 Press [ATA MENU] key. 2 Press [1] key. The ATA Setting menu will appear. 3 Press [9] key. The Target Number Display is switched ON or OFF. ON: Displays target ID numbers. OFF: Hides target ID numbers. ARPA TRACK: Displays target ID number with ARPA track. If there are many tracking targets and their symbol display is confusing, set Target Number Display to OFF to view the radar display easily. ATA Setting 1. Vector Time 2. Past Position 3.

(Refer to Example of Display in page 2-1. ) Display of Vectors Attention l When a target or own ship changes a course, or when a target is acquired, its vector may not reach a given level of accuracy until three minutes or more has passed after such course change or target acquisition. Even if three minutes or more has passed, the vector may include an error depending upon the tracking conditions. A vector to represent a targets predicted position can presented in the True vector or Relative vector mode. In each mode, a vector length can be freely changed for a time interval of 1 to 60 minutes. The True and Relative vector can be switched by using buttons 47 shown in the radar display on page 2-7.
[I] Vector Mode Selection True Vector Mode In the true vector mode, the direction of a target vector indicates the true course of the target and its vector length is proportional to its speed. In this mode, own ships vector is displayed as shown below. In this mode, the movements of other ships around own ship can be accurately and easily monitored. However, no CPA RING can appear in this mode. HL Own Ships Vector True Vector 521 The relative vector is not displayed 5.3 ATA/ARPA OPERATION Relative Vector Mode In displaying the relative vector of a target, press the [VECT R/T] key to select the Relative Vector mode. The relative vector does not represent the true motion of the target, but its relative relation with own ship. This means that a target with its relative vector directed to own ship (passing through the CPA LIMIT ring) will be a dangerous target. In the Relative Vector mode, it can be seen at a glance where the CPA LIMIT of the dangerous target is. HL 5 The true vector is not displayed CPA ring Relative Vector Therefore, the TRUE/REL mode shall optionally be used for the purpose of observation: the TRUE vector mode for grasping the true aspect of a target, and the REL vector mode for grasping a targets closest point of approach (CPA) 522
[II] Vector Length: VECTOR TIME The vector length of a target is proportional to its speed, and the vector time can be switched in a range of 1 to 60 minutes by used for ten-key. The diagram below illustrates a vector length of a target for six minutes, and the tip of the vector represents the targets position expected to reach six minutes later. HL Refer to Section 5.1.4 Setting Vectors for how to change the vector time. Current Position Future Predicted Position

Dangerous target alarm:
Guard zone entry alarm:
Lost target alarm:
System function alarm:
Gyro set alarm:
CPA/TCPA GZ LOST ARPA (DATA) SET GYRO Dangerous Target Alarm CAUTION Since these alarms may include some errors depending on the target tracking conditions, the navigation officer himself should make the final decision for ship operations such as collision avoidance. Making the final navigation decision based only on the alarm may cause accidents such as collisions. 5 In the ARPA system, targets are categorized into two types: tracked targets and dangerous targets. The grade of danger can easily be recognized on the display at a glance. So the officer can easily decide which target he should pay attention to. The types of target and alarm are shown below. Dangerous Target Alarm Status Symbol on display Alarm characters Alarm sound Tracking target OFF
(OFF) Dangerous target TCP/TCPA Beep sound (pee-poh) Acknowledgeable Conditions CPA>CPA LIMIT 0>TCPA TCPA>TCPA LIMIT CPACPA LIMIT, 0TCPATCPA LIMIT CPA LIMIT and TCPA LIMIT: The Setting Values 530 Guard Zone Alarm CAUTION In setting a guard zone, it is necessary to adjust the gain, sea clutter suppression and rain/snow clutter suppression to ensure that target echoes are displayed in the optimum conditions. No guard zone alarms will be issued for targets undetected by the radar, and this may cause accidents such as collisions. The guard zone functions are to set a zone at an arbitrary range and to deliver an alarm if any target intrudes within this zone. For the method of setting a guard zone, refer to page 3-60, section 3.5.19 Set Guard Zones. HL Guard Zone Guard Zone Alarm Status Symbol on display Alarm characters Alarm sound Conditions Target entering the guard zone GZ Beep sound (pipipi) Acknowledgeable An alarm sound is generated while a target has entered into the range of 0.5 NM between the outer and the inner ring. 531 5.3 ATA/ARPA OPERATION Lost Target Alarm Attention l If the gain, sea clutter suppression, rain/snow clutter suppression are not adjusted adequately, the lost target alarm may be easily generated. So such adjustments should be mad carefully. When it is impossible to continue tracking any acquired and tracked target, the LOST target alarm will be generated. The typical causes for alarm generation are shown below, but not limited to the following:
The target echo is very weak. The target is shadowed by a shore or a large ship and its echo is not received. The target echo is blurred by sea clutter returns. 5 HL Lost Target Lost Target Alarm Status Symbol on display Alarm characters Alarm sound Conditions Lost target LOST Beep sound (pee) Acknowledgeable The alarm will sound once when a lost target symbol is displayed. 532 System Function Alarm When an abnormal state of an input signal or a trouble in the processing circuitry occurs, an character or alarm is generated. When an alarm occurs against any ARPA function, ARPA (DATA) will appear in the WARNING display area, but no indication is made in the ARPA information display. This status means that there is any operational trouble in the ARPA system. Please, contact the service depot or the manufactures. System Function Alarm Alarm characters Alarm sound Conditions ARPA(DATA) Beep sound (pipipi) An alarm sound is generated when an ARPA circuit error occurs. Gyro Set Alarm The North Stabilizing Kit (NSK) in this system receives signals from a gyro. Even if the power is turned off, the system will follow up the gyro. However, the system stops the follow-up operation when the power of the master gyro is turned off or when any trouble occurs to the line. When the power of the master gyro is recovered, the SET GYRO alarm will be generated. If this alarm occurs, set the gyro. Gyro Set Alarm Alarm characters Alarm sound Conditions SET GYRO Beep sound (pipipi) The signals from the gyro are stopped, but the gyro is recovered. 533 5.3 ATA/ARPA OPERATION 5.3.7 Trial Maneuvering (Trial) Attention l Trial maneuvering is to simulate own ships course Attention: Trial maneuvering can be done only when the ARPA option is installed. Trial maneuvering is and speed in the conditions that the course and speed of a target ship are unchanged as they are. As the situation is different from any actual ship maneuvering, set values with large margins to CPA Limit and TCPA Limit. unavailable if the ATA option is installed. The trial maneuvering is the function of simulating own ships course and speed for collision avoidance when a dangerous target appears. When manually entering own ships course and speed against the data of the acquired target, it is checked whether the situation is dangerous or not. The ranges of course and speed to be entered manually:
Course: 360 (in 0.1 intervals)........................................................................... [EBL] control Velocity: 0 to 100 knots (in 0.1 knot steps)........................................................... [VRM] control 5 534 Trial Maneuvering in the True Vector Mode In the True Vector mode, calculations are performed according to the values set by Trial Speed and Trial Course, and the result is displayed as a bold-line that represents the change of own ships vector as shown in the figure below (an example of the course changed to the right). In this figure, the dangerous target forward right becomes safe as a result of simulation. The target data display field indicates the current CPA LIMIT and TCPA LIMIT values regardless of the result of simulation. Dangerous target HL NORMAL Own ship Change of symbol as a result of trial maneuver TRIAL HL Change in course Own ship T Trial Speed (vector time) 535 5.3 ATA/ARPA OPERATION Trial Maneuvering in the Relative Vector Mode The result of Trial maneuvering in the Relative Vector mode is shown by a change in target vector. In the figure below (in the same conditions as in the True Vector mode in the previous page), it is seen that the acquired target is a dangerous one because its vector is crossing the CPA RING. Dangerous target NORMAL HL Own ship CPA RING Change of symbol as a result of Trial maneuver TRIAL HL Change in course 5 Own ship T CPA RING The above figure shows that the relative vector of the target has changed as shown in the figure as a result of simulation (course and speed), so that the targets symbol is changed into , a safe target. The data display field indicates the current values of CPA LIMIT and TCPA LIMIT, not those as the result of simulation, same as in the True Vector mode. The course change of own ship is displayed as a dotted-lime. 536 Executing the TRIAL Function Procedures Exit 1 Press [ATA MENU] key. 2 Press [1] key. 3 Press [6] key.

As shown in the table below, the time until target data is deleted varies depending on the class of receive data and the target status.
[SOLAS ship] (Class A) Target Status Time until data deletion Vessel below 3 knots and it is now at anchor or on the berth Vessel of 3 knots or more and it is now at anchor or on the berth Vessel of 0 to 14 knots Vessel of 0 to 14 knots and it is now changing the course Vessel of 14 to 23 knots Vessel of 14 to 23 knots and it is now changing the course Vessel of 23 knots or more Vessel of 23 knots or more and it is now changing the course 18 min 60 sec 60 sec 60 sec 36 sec 36 sec 12 sec 12 sec 5
[Non-SOLAS ship] (Class B) Target Status Time until data deletion Vessel below 2 knots Vessel of 2 to 14 knots Vessel of 14 to 23 knots Vessel of 23 knots or more 18 min 180 sec 90 sec 30 sec Reference:
When a dangerous target ship is lost, a lost alarm is issued and the symbol changes to a lost symbol. The system calculates the current position from the last-received data and continues displaying the symbol for a maximum of one minute. If the system cannot receive any data within one minute or the ALARM ACK switch is pressed, the symbol is cleared. When a safe target ship is lost, the system does not issue a lost alarm, display a lost symbol, or calculate the current position. 566 5.4.11 Displaying AIS Symbols Maximum number of targets and the display priority Attention l When the system receives the data of the 51-th target A radar of the JMA-5300 series displays AIS symbols for a maximum of 50 targets. When 51 AIS targets or more exist, they are displayed according to the following priority:
ship, it displays AIS MAX TARGET at the right lower of the radar display, and issues audible alarm (beep sound of pipi). 1. Target for which numeric data is displayed 2. Target displayed by the AIS target search function 3. arget in the AIS filter 4. Target whose CPA/TCPA is the set value or less. 5. Targets other than the above, which are outside the AIS filter
(Target for which a dangerous ship alarm has been issued)
(Targets closer to the own ship in the filter have higher priority.)
(Targets closer to the own ship in the filter have higher priority.) Displaying the vectors of AIS symbols Attention l If a vector is not displayed even when the AIS symbol is activated, probable causes are as follows:
1. COG/SOG from the GPS has not been entered. 2. The selected speed sensor is malfunctioning. The vector of an AIS symbol is to be displayed as a vector over water or over ground, depending on the speed sensor setting and current offset setting. The type of the currently displayed vector is confirmed in the own ships information display area at the upper right of the radar display. When GND is displayed to the right of OS STAB: Vector over ground When SEA is displayed to the right of OS STAB: Vector over water When the vector of an AIS symbol is displayed as a vector over water, the system has converted the AIS symbols vector over ground to the vector over water according to the data received from the AIS and the own ships information. 567 5.4 AIS OPERATION 5.4.12 AIS Alarm Display Alarm messages for the AIS system:

For this purpose, the operator has to observe the radar displays after fully understanding the advantages and disadvantages that the radar has. For better interpretation of radar display, it is important to gain more experiences by operating the radar equipment in fair weathers and comparing the target ships watched with the naked eyes and their echoes on the radar display. The radar is mainly used to monitor the courses of own ship and other ships in open seas, to check buoys and other nautical marks when entering a port, to measure own ships position in the coastal waters relative to the bearings and ranges of the shore or islands using a chart, and to monitor the position and movement of a heavy rain if it appears on the radar display. Various types of radar display will be explained below. 61 6.1 RADAR WAVE WITH THE HORIZON Radar beam radiation has the nature of propagating nearly along the curved surface of the earth. The propagation varies with the property of the air layer through which the radar beam propagates. In the normal propagation, the distance (D) of the radar wave to the horizon is approximately 10% longer than the distance to the optical horizon. The distance (D) is given by the following formula:
D=2.23(
h1 +
h2
)(nm) h1: Height (m) of radar scanner above sea level h2: Height (m) of a target above sea level Figure 6.1 is a diagram for determining the maximum detection range of a target that is limited by the curve of the earth surface in the normal propagation. Radar Earth 6 Targets 62 D (nm) Height of Radar Scanner Detective Range Figure 6.1 Height of Target When the height of own ships scanner is 10 m for instance,
(a) A target that can be detected at the radar range of 64 nm on the radar display is required to have a height of 660 m or more. If the height of a target is 10 m, the radar range has to be approx. 15 nm. However, the maximum radar range at which a target can be detected on the radar display depends upon the size of the target and the weather conditions, that is, the radar range may increase or decrease depending upon those conditions.
(b) 63 6.2 STRENGTH OF REFLECTION FROM THE TARGET The signal intensity reflected from a target depends not only on the height and size of the target but also on its material and shape. The echo intensity from a higher and larger target is not always higher in general. In particular, the echo from a coast line is affected by the geographic conditions of the coast. If the coast has a very gentle slop, the echo from a mountain of the inland appears on the radar display. Therefore, the distance to the coast line should be measured carefully. Mountain displayed on the radar display Sea shore line not displayed on the radar display. Figure 6.2 6 64 6.3 SEA CLUTTERS When the sea surface ruffles, bright echo returns spread around the center of the radar display. The higher the waves are, the echo returns are larger. Swirling currents may appear as a smooth line like a coastal line. 65 6.4 FALSE ECHOES The radar observer may be embarrassed with some echoes that do not exist actually. These false echoes appear by the following causes that are well known:
[I] Shadow When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction of the funnel or mast cannot appear on the radar display because the radar beam is reflected on the funnel or mast. Whether there are some false echoes due to shadows can be checked monitoring the sea clutter returns, in which there may be a part of weak or no returns. Such shadows appear always in the same directions, which the operator should have in mind in radar operation.
[II] Side Lobe Effect A broken-line circular arc may appear at the same range as the main lobe of the radar beam on the radar display. This type of false echo can easily be discriminated when a target echo appears isolated. (See Figure 6.3) 6 Figure 6.3
[III] False Echo by Secondary Reflection When a target exists near own ship, two echoes from the single target may appear on the radar display. One of those echoes is the direct echo return from the target and the other is the secondary reflection return from a mast or funnel that stands in the same direction as shown in Figure 6.4. Actual target False echo from funnel Direct microwave Radar scanner Funnel Secondary reflection of microwave Figure 6.4 66
[IV] False Echo by Multiple Reflection When there is a large structure or ship with a high vertical surface near own ship as shown in Figure 6.5, multiple refection returns may appear on the radar display. These echoes appear in the same intervals, of which the nearest echo is the true echo of the target.
[V] Abnormal Propagation Figure 6.5 The maximum radar detection range depends upon the height of the scanner and the height of a target as described in the section of The Horizon for Radar Beam Radiation. If a so-called duct occurs on the sea surface due to a certain weather condition, however, the radar beam may propagate to a abnormally long distance, at which a target may be detected by the radar. For instance, assuming that the radar range is 6 NM (on the repetition frequency of 1100 Hz), the first pulse is reflected from a target at about 76 NM or more and received during the next pulse repetition time. In this case, a false echo appears at a position that is about 76 NM shorter than the actual distance. If the false echo appears at 5 NM on the radar display, the true distance of the target is 5+76=81 NM. On the radar range scale of 1.5 NM (on the repetition frequency of 1900 Hz), a false echo may appear at a position that is about 43 NM shorter than the actual distance. This type of false echo can be discriminated by changing over the range scale (the repetition frequency), because the distance of the target changes accordingly. 67 6.4 FALSE ECHOES
[VI] Radar Interference When another radar equipment using the same frequency band as that on own ship is near own ship, a radar interference pattern may appear on the radar display. This interference pattern consists of a number of spots which appear in various forms. In many cases, these spots do not always appear at the same places, so that they can be discriminated from the target echoes. (See Figure 6.6) Figure 6.6 If radar equipment causing an interference pattern and this radar are of the same model, their transmitting repetition frequency is nearly the same. As a result, interference patterns may be displayed concentrically. In this case, the interference patterns cannot be eliminated by using only the interference reflector function, so press [TX/PRF] several times to fine-tune the transmitting repetition frequency. An interference suppressing effect can be heightened by applying a different transmitting repetition frequency to the interference pattern source radar and this radar. 6 68 6.5 DISPLAY OF RADAR TRANSPONDER
(SART) The SART (Search and rescue Radar Transponder) is a survival device authorized by the GMDSS (Global Maritime Distress and Safety System), which is used for locating survivors in case that a distress accident occurs at sea. The SART is designed to operate in the 9 GHz frequency band. When receiving the 9 GHz radar signal (interrogating signal) transmitted from the radar equipment on a rescue ship or search aircraft, the SART transmit a series of response signals to inform the distress position to the rescue and search party.

l When the SART function is set to ON to detect the SART signal, small targets around own ship will disappear from the radar display. So it is necessary to exercise full surveillance over the conditions around own ship by visual watch in order to avoid any collision or stranding. If two or more sets of radar equipment are installed on own ship, use one set of 9 GHz band radar for detection of the SART signal and operate others as normal radars for avoiding collision, monitoring targets around own ship, and checking on own ships position and avoidance of stranding. After end of detecting the START signal, turn the START display off. Then the radar returns normally to the nautical mode. 6 610 SECTION 7 MAINTEMANCE 7.1 Routine Maintenance.................................... 7-1 7.2 Maintenance on Each Unit ........................... 7-2 Scanner Unit NKE-2102/2252/1075A............ 7-2 Display Unit NCD-4510 ................................. 7-8 7.1 ROUTINE MAINTENANCE WARNING Never carry out internal inspection or repair work of the equipment by users. Inspection or repair work by unauthorized personnel may result in fire hazard or electric shock. Ask the nearest branch, business office or a dealer for inspection and repair. Turn off the main power before maintenance work. Otherwise, an electric shock may result. Turn off the main power before cleaning the equipment. Especially, make sure to turn off the indicator if a rectifier is used. Otherwise, equipment failure, or death or serious injury due to electric shock may result, because voltage is outputted from the rectifier even when the radar is not operating. For operating the radar equipment in the good conditions, it is necessary to make the maintenance work as described below. If maintenance is made properly, troubles will reduce. It is recommended to make regular maintenance work. Common points of maintenance for each unit are as follow:
Clean the equipment. Remove the dust, dirt, and sea water rest on the equipment cabinet with a piece of dry cloth. Especially, clean the air vents with a brush for good ventilation. 71 7.2 MAINTENANCE ON EACH UNIT Scanner Unit NKE-2102/2252/1075A WARNING Turn off the main power source before starting maintenance. Otherwise, an electric shock or injury may be caused. Turn off the main power if you need to be near the scanner unit for maintenance or inspection purposes. Direct exposure to electromagnetic waves at close range in death or serious injury. Set the safety switch for stopping the scanner unit to the OFF position. Otherwise, an accidental contact with the rotating scanner unit may cause injury. 7 72 CAUTION Do not put watches, clocks, or magnetic cards close to the modulator unit since this unit holds magnetrons having strong magnetic force. Failure or data destruction of the above devices may result. After finishing the maintenance work, reset the safety switch to the ON position. Precautions in Mounting the Cover When the cover is removed for regular checkup and replacement of parts and refitted after such work, the procedures of fastening bolts shall be taken with the following precautions:
(a) The proper fastening torque of the fitting bolts (M8) is 1176 to 1470 Ncm (120 to 150kgfcm) (which makes the inside water-tight and protects the packings against permanent compressive strain). The packings start producing from the cover at a torque of approximately 1470Ncm (150kgfcm). Do not fasten the bolts with a torque exceeding the specified value. Otherwise, the screws may be broken.
(b) Use an offset wrench of 11 mm 13 mm or a double-ended wrench of 13 mm 17 mm (not longer than
(c) Screw all the bolts by hand first to prevent them playing, then fasten them evenly in order not to cause one-sided fastening. (Fasten the bolts with 25% of the required torque at the first step.) 200 mm).
*: Fasten the bolts in the diagonal order. 73 7.2 Maintenance on each Unit Top View of NKE-2102 Bolt Tightening Procedure of NKE-2102 Cover 7 Side View of NKE-2252 Bolt Tightening Procedure of NKE-2252 Cover 74 Side View of NKE-1075A Bolt Tightening Procedure of NKE-1075A Cover 75 7.2 Maintenance on each Unit Attention l If the radiator front face (radiation plane) is soiled with smoke, salt, dust, paint or birds droppings, wipe it with a piece of soft cloth wetted with alcohol or water and try to keep it clean at all times. Otherwise, radar beam radiation may attenuate or reflect on it, resulting in deterioration of radar performance. l Never use solvents of gasoline, benzine, trichloroethylene and ketone for cleaning. Otherwise, the radiation plane may deteriorate.
(1) Radiator Check up and clean the radiator. 7 76
(2) Rotating section
(a) Supply Oil Seal When there is not a grease nipple, the replenishment of grease oil is unnecessary. Remove the cap on the grease nipple located on the side of the X band radar or on the front of S band radar at which the radiator is supported, and grease with a grease gun. Make the oiling every six months. The oil quantity shall be approximately 100 g, which is as much as the grease comes out of the oil seal. Use the grease of Mobilux 2 of Mobil Oil.
(b) Oiling gears
(c) Mounting legs Apply grease evenly to the tooth surfaces of the main shaft drive gear and the encoder drive gear with a spreader or brush. Oiling in short intervals is more effective to prevent the gears from wear and tear and extend their service life, but oil at least every six months. Use Mobilux2 of Mobile Oil. Check the mounting legs and mounting bolts of the scanner unit case for corrosion at intervals and maintain them to prevent danger. Apply paint to them once a half year because painting is the best measure against corrosion. 77 7.2 Maintenance on each Unit Display Unit NCD-4510 WARNING When cleaning the screen, do not wipe it too strongly with a dry cloth. Also, do not use gasoline or thinner to clean the screen. Otherwise the screen surface may be damaged. Dust accumulated on the screen will reduce clarity and darken the video. For cleaning it, wipe it with a piece of soft cloth (flannel or cotton). Do not wipe it strongly with a piece of dry cloth nor use gasoline or thinner. 7 78 SECTION 8 TROUBLE SHOOTING AND ADJUSTMENT 8.1 Performance Check..........................8-1 8.2 Fault Finding...................................8-21 8.3 Trouble Shooting............................8-22 8.4 Replacement of Major Parts ..........8-27 8.5 Adjustments....................................8-30 8.6 Setting .............................................8-62 8.1 PERFORMANCE CHECK Make operational check on the radar equipment regularly and if any problem is found, investigate it immediately.

In general, the relatively many causes are disconnection in a high-value resistor due to moisture, a defective variable resistor and poor contact of a switch or relay. Some troubles are caused by defective parts, imperfect adjustment (such as tuning adjustment) or insufficient service (such as poor cable contact). It will also be effective to check and readjust these points. Melted fuses are caused by any clear cause. When a fuse is replaced, it is necessary to check the related circuits even if there is no trouble. In checking, note that there is some dispersion in the fusing characteristics. Table 8-12 shows a list of fuses used in the equipment.

Otherwise, an electric shock or trouble may be caused. Before replacing the magnetron, turn off the main power source and wait for 5 minutes or more until the high voltage circuits are discharged. Otherwise, an electric shock may be caused. Take off your wrist watch when bringing your hands close to the magnetron. Otherwise, your watch may be damaged because the magnetron is a strong magnet. Two or more persons shall replace the liquid crystal monitor. If only one person does this work, he may drop the LCD, resulting in injury. Even after the main power source is turned off, some high voltages remain for a while. Do not contact the inverter circuit in the LCD with bare hands. Otherwise, an electric shock may be caused. 827 8.4 Replacement of Major Parts Parts Required for Periodic Replacement Here are parts required for periodic replacement Part name Interval 4000 hours 10000 hours 50000 hours 20000 hours 3 years 1.

Backup battery Replacement of magnetron (V1/V201) Remove the shield cover of the modulator and check that no charge remains in the high-voltage modulator circuit. Then, remove the socket of the magnetron. The magnetron can be demounted by removing the screws fixing it. When mounting a new magnetron, do not touch the magnet with a screwdriver or put it on an iron plate. After replacement, connect the lead wire correctly. Handling of Magnetron under Long-Time Storage The magnetron that has been kept in storage for a long time may cause sparks and operate unstably when its operation is started. Perform the aging in the following procedures:
(1) Warm up the cathode for a longer time than usually. (20 to 30 minutes in the STBY state.)
(2) Start the operation from the short pulse range and shift it gradually to the longer pulse ranges. If the operation becomes unstable during this process, return it to the standby mode immediately. Keep the state for 5 to 10 minutes until the operation is restarted. Replacement of TRHPL (A303)(JMA-5330-12) Remove the 4 screws fixing the TRHPL with receiver and remove the TRHPL. When mounting the TRHPL, take care of the mounting direction and mount it in the arrow direction facing it the receiver front end. Replacement of Diode Limiter (A303)(JMA-5310-6, JMA-5320-7/9/6HS) Remove the 4 screws fixing the receiver. Remove the 4 screws fixing the diode and the limiter, and remove diode limiter. When mounting the diode limiter, take care of the mounting direction and mount it in the arrow direction facing it the receiver front end. Connect the wiring in the same way as before the replacement. 8 828 Replacement of LCD Monitor Attention l When replacing the LCD monitor, which is easily 1 JMA-5310-6, JMA-5320-7/9/6HS, JMA-5330-12 (Display Unit: NCD-4510) broken by a little impact, handle it carefully and do not hit any article against it or put it on a hard article.

If the level deviates from the proper value, the ARPA acquisition and tracking functions will deteriorate. Otherwise, this may cause accidents. The quantization level determines the minimum signal level of the input video to the ARPA target detection circuit. In this test, the value of the quantization level can be set in a range of 1 to 63. If the value is set to a lower level, weak target echoes will be inputted to the ARPA target detection circuit, but much radar noise will also be inputted to the circuit together, and target acquisition and tracking may be disabled. Therefore, it is important to set a value that is 4 or 5 higher than the detected noise level. Procedures Exit 1 Press [9] key while the Adjust Menu is open.
