Note:

z Wait for about 2 seconds before turning on the power again. z Immediately after the radar is installed, at start of the system after it has not been used for a long time, or after the magnetron is replaced, preheat the equipment in the standby state for 20 to 30 minutes before setting it into the transmit state. z If the preheating time is short, the magnetron causes sparks, resulting in its unstable oscillation. Start transmission on a short-pulse range and change the range to the longer pulse ranges in turn. If the transmission is unstable in the meantime, immediately place the system back into the standby state and maintain it in the standby state for 5 to 10 minutes before restarting the operation. Repeat these steps until the operation is stabilized. Power On 1 Press the [STBY] key on the display unit to turn on the display unit.

The display unit is turned on, and the preheating time screen is displayed.

When the preheating time is over, the preheating time screen disappears. 2-4 Chapter 2 OPERATIONS 2.3 POWER ON/OFF Starting transmission 1 Press the [TX/PRF] key.

WARNING When conducting maintenance work, make sure to turn off the power and unplug the power connector J1 of the display unit 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. 2-5 2 L A U N A M N O T C U R T S N I I Chapter 2 OPERATIONS 2.4 SENSITIVITY ADJUSTMENT 2.4 SENSITIVITY ADJUSTMENT Sensitivity can be adjusted. Adjust the noise on the display unit to achieve better observation state. CAUTION If sensitivity is set too high, unnecessary signals such as noises in the receiver and false echoes increase to lower target visibility. At the same time, if sensitivity is set too low, detection of targets such as ships and dangerous objects may be hindered. Therefore, sensitivity must always be set to an optimal level. Noise Adjustment 1 Turn the [GAIN] control.

Turn the [GAIN] control clockwise to increase sensitivity. Turn the [GAIN] control counterclockwise to decrease sensitivity. The sensitivity adjustment screen appears when turning the [GAIN] control. Sensitivity can be adjusted between 0 and 100.

When turning the [GAIN] control, the gain control indication is stretched or shrunk.

2-6 Chapter 2 OPERATIONS 2.4 SENSITIVITY ADJUSTMENT z [GAIN] Control Turning the [GAIN] 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] control counterclockwise to reduce the sensitivity so that the targets are easy to observe. However, be careful not to overlook important small targets. Switching to Manual/Automatic Mode 1 Hold down the [GAIN] control.

The sensitivity can be switched between manual and automatic modes. The mode is indicated as shown below. 2 L A U N A M N O T C U R T S N I I

2-38 Chapter 2 OPERATIONS 2.7 SOFT KEY OPERATION Setting AIS Symbol Display For details of displaying/hiding of the AIS symbols, see Section "2.7.16 SETTING SYMBOL ". 2.7.7 TT OPERATIONS The target tracking function calculates the course and speed of a target by automatically tracking the target's move. Note:

z There are the following limitations on use of the target acquisition and target tracking functions.

[I] Resolution between adjacent targets and swapping during automatic target tracking Depending on the particular distance and echo size, resolution between adjacent targets during automatic target tracking usually ranges somewhere between 0.03 to 0.05 NM. If multiple targets approach each other, resolution will become about 0.05 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 target 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 seven 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. To execute accurate tracking, it becomes necessary 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 adjustments reduce the reliability / accuracy of automatic tracking. 2-39 2 L A U N A M N O T C U R T S N I I Chapter 2 OPERATIONS 2.7 SOFT KEY OPERATION 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. Use the target tracking function (TT) 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 target tracking function (TT) information may cause accidents. The target tracking function (TT) information such as vector, target numerical data, and alarms may contain some errors.

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. 2.15-1 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. Fig. 2.15-1 Navigation Pattern

2-120 Chapter 2 OPERATIONS 2.15 SETTING TT/AIS 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. 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. 2.15-2 shows a diagram called "Collision Triangle". Fig. 2.15-2 Collision Triangle

2-121 2 L A U N A M N O T C U R T S N I I Chapter 2 OPERATIONS 2.15 SETTING TT/AIS 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 ship's aspect. The relationship between the relative vector and true vector is shown in Fig. 2.15-3. Furthermore, the meanings of both vectors are described. 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 ship's 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. Fig. 2.15-3 Relative Vector and True Vector Target ship true vector N O Vo CPA N VT T A R VO: Own ship's speed O: Own ship's course VT: Other ship's true speed T: Target ship's true course VR: Target ship's relative speed R: Target ship's relative course A: Aspect VR Relative vector Own ship 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. 2-122 Chapter 2 OPERATIONS 2.15 SETTING TT/AIS 2.15.2 PREPARATION Initializes Tracking Target and AIS Function
