WARNING HIGH VOLTAGE There is no danger in handling the external controls of the Radar while the Radar is in operation. However, in the Radars interior are high voltages which are fatally dangerous to anyone carelessly handling interior components. Be absolutely sure that the Radar power switch or the Radar system is switched OFF before performing repair work or maintenance. Furthermore, even when the Radar power switch or the Radar system is turned OFF, a high voltage remains in certain parts of the Radar circuits. In particular, be careful of the magnetron heater circuit, cathode- ray tube anode circuit, etc. Before touching any part of the voltage sections, use a length of wire with one end fully grounded or an insulated screwdriver to ground all high voltage sections in order to discharge the residual charges and ensure that no charges remain. In any case, the most dangerous thing to do is to touch any part of the high voltage sections without making sure that the Radar power switch or the Radar system must be switched OFF. WARNING Exercise care when approaching a rotating antenna. Be Edition July 2015 1-5 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual sure to turn OFF the Radar power switch or the Radar system before performing maintenance or inspection of the antenna.

Its accuracy can be affected by many factors such as equipment defect, environmental conditions, or improper operation. It is the users responsibility to exercise common prudence and navigational judgment at all times. The sensitivity controls describe all adjustments to find the best video performance. The video performance depends from the current weather conditions, Radar sensitivity adjustments, magnetron performance, pedestal and array conditions and transfer line conditions (coax cable and wave guide). Radar in Slave mode:

If the Radar is working in slave mode the sensitivity controls AUTO Tune and Pulse width selection are not possible. 2.3.1.1 Gain and Clutter Processing The Radar uses a digital video processing technique called Scan to Scan integration or field processing. This process requires 3 complete antenna rotations or scans of the antenna in order to build up or decay detected targets. To the operator, this means that when a target is first detected, it appears dim. If, on the next scan, it is still present at the same location, it appears at medium brightness and on the third scan, it appears at full brightness. As long as the target is present, it will appear at full brightness. If the target fades in and out, then it will remain on the screen, dropping from full brightness to medium and back to full brightness. If the target is lost altogether, then it will take three scans before it completely disappears. It is essential to understand that this 3 scan integration is crucial for operation of the Gain, Sea and Rain clutter controls, because if an adjustment is made to any of these controls, it requires 3 complete scans to properly observe the results of the adjustment. The same applies if a Radar target is used as a tuning indicator when manually tuning the Radar. 4265.DOC020102 2-40 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 2.3.1.2 Tune MANual TUNE The tune function uses the trackball to control tuning of the receiver frequency to match that of the transmitter. Recommendation before using the tuning control. To improve a good target reception and a minimal clutter effect we advise to switch the pulse width selection to medium pulse (M2) or to long pulse (LP). Operator controls Task For a preliminary manual setting:

Switch first to manual tune by clicking on the AUTO soft button. Use the trackball to place the cursor on the TUNE slider then press the left trackball button. Rotate the trackball for maximum deflection of the slider. As this setting must be averaged over a complete antenna revolution, a peak detector is included for operator convenience. The tip of the tuning bar remains at the peak signal detected during one complete revolution of the antenna. Bear in mind the fact that the transmitter frequency will drift for the first thirty (30) minutes of operation from a cold start due to inherent magnetron characteristics. As a result of this, the receiver tuning will change during this time and a final tuning adjustment should be made after approximately thirty (30) minutes of operation. The tuning should also be checked at every four hours thereafter. Edition July 2015 2-41 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual AUTO TUNE (only available in Master mode) When auto tuning is activated, manual tuning is not available. The slider symbol is hidden. With automatic receiver adjustment, the tendency indicator adjusts itself to the maximum value. If the magnetron is at the end of its service life and the transmission spectrum has become abnormal, select manual tuning. 2.3.1.3 Gain The GAIN control adjusts the sensitivity of the Radar video. If properly adjusted, the GAIN control results in noise appearing as a light speckle at the dim level. This light speckle setting results in maximum detectability of targets against background noise. If GAIN is set too low, weak or distant targets could be missed. Excessive gain increases background noise and could make target detection more difficult. A gain slider is provided to indicate the GAIN control setting. Once the GAIN control has been set, it will automatically maintain the same setting for all ranges. It is not necessary to readjust whenever a new range scale is selected. However, it should be adjusted to optimize the Radar video as clutter (sea and/or rain) conditions change. The gain control function is active over its entire rotation range. Operator controls Task Use the trackball to place the cursor on the GAIN slider then press the left trackball button. Rotate the trackball to adjust the optimal GAIN value. 4265.DOC020102 2-42 Edition July 2015 2.3.1.4 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Sea The Sea control is used to suppress Radar returns which are the result of Radar signals reflected from waves. This effect is commonly known as sea clutter. The effects of sea clutter are greater (more reflected energy) at close range and vary with wave height and wind. It should also be noted that sea clutter is reduced on the leeward side of the ship as the retreating wave fronts do not provide as many Radar returns as oncoming waves. Small targets (buoys, etc.) often return nearly the same energy as do the waves and can, therefore, be lost in the clutter. However, since sea clutter is random in nature, the gain and clutter processing circuitry together with the SEA control allow the operator to reduce the sea returns to a light background speckle at low brightness level while maintaining targets in the sea clutter at full brightness. The effect of the Sea control is greatest at short range. Its effect reduces progressively as the range increases. At a range determined by the height of the Radar antenna above the water (and other factors), the effect of the SEA control ceases altogether. This is typically about 8- 10 NM. The ideal sea control setting will reduce sea returns to a light speckle. Scan- to-

scan integration will keep the sea returns at a low brightness level, while targets in the sea clutter will be shown at full brightness. The sea clutter control should be adjusted in small increments, with pauses to observe 3 scans for the results. In heavy sea clutter, some clutter peaks may come through at brighter levels, especially rollers, so an average setting should be chosen. It is important to note that if the Sea Clutter control is adjusted to completely remove all clutter, then some targets may not be detected. The Radar uses gyro and speed information as part of the clutter removal process. It is therefore highly recommended that you use gyro stabilization and ensure that the manual speed or speed log input is accurate. In heavy wind driven seas where more sea clutter appears on the windward side of the ship, a slight amount of FTC can balance the clutter (chapter 2.3.1.7) before adjusting the SEA control. If too much SEA is applied during periods of light clutter, then a band of noise could appear on the edges of the sea clutter. Edition July 2015 2-43 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Operator controls Task Use the trackball to place the cursor on the SEA slider then press the left trackball button. Rotate the trackball to adjust the optimal SEA clutter value. 2.3.1.5 Rain Rate The function of the RAIN control is to enable the operator to suppress Radar returns which are the result of Radar signals reflected from rain drops. This effect is commonly known as rain clutter. As with sea clutter, the rain clutter tends to mask small targets (or large targets if the rain is intense). When heavy rain is falling in the vicinity of the operators ship (up to 6- 10 NM) and the resulting rain clutter is obscuring nearby targets, then the rain rate slider should be used. Advance the rain rate control slightly and observe the results (wait 3 scans). The ultimate goal is to reduce the nearby rain clutter until it is a very light speckle at the dim level. This setting will reduce the rain returns and will have little effect on strong constant target video returns. Weaker targets (usually appear where rain returns are less intense) may be suppressed along with the rain. Most of these weaker targets can be restored by making a FTC adjustment

(chapter 2.3.1.7). Operator controls Task Use the trackball to place the cursor on the RAIN slider then press the left trackball button. Rotate the trackball to adjust the optimal RAIN clutter value 4265.DOC020102 2-44 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 2.3.1.6 Automatic Clutter Reduction When AUTO is activated FTC are hidden. This AUTO mode describes a control algorithm, which uses the evaluation of echoes to calculate statistical average values for SEA and RAIN. These average values are used for optimization of the Radar video. Adjust the GAIN slider to control the sensitivity of the Radar. Operator controls Task Switch over to AUTOmatic clutter reduction. Use the trackball to place the cursor on the GAIN slider then press the left trackball button. Rotate the trackball to adjust the sensitivity of the Radar. Use of AUTO simplifies Radar video optimization. However, depending on the weather conditions misinterpretations are possible. The algorithms for Automatic Sea Clutter suppression

(AUTO) have been developed based on data recorded on several sea trials. As this functionality has been optimized applying it to these scenarios sea states and environmental conditions might be encountered where these anti- clutter algorithms do not result in a Radar video presentation satisfying the expectations of the user. If you find yourself in a situation where the Radar presentation does not correspond to the information you receive from other equipment or your own observations it is highly recommended to switch to manual sea clutter suppression to achieve the optimum presentation of the sea area. It will be highly appreciated if you will inform Raytheon Anschuetz in case of such an experience so that appropriate measures could be taken to improve the automatic sea clutter suppression function. Edition July 2015 2-45 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 2.3.1.7 Filtering Rain Clouds FTC FTC is responsible for differentiation or removing the mean clutter level of rain clouds. Adjusting the FTC will also reduce the land echoes and thin out larger targets in range. Operator controls Task Step 1 Select FTC Advance the FTC control slowly (remember the 3 scans) until only the leading edges of the rain clutter are visible. As the FTC is increased, weaker returns will reappear. Stronger returns will begin to reduce in the visible area. Too much FTC will shorten or delete RACON responses. Step 2 For fine adjustment use the RAIN slider The best setting will be a balance between restoration of weaker returns and adequate size of the stronger returns. Noising effect by maximum GAIN control With FTC ON a false noise ring may be displayed. This effect can be compensating by reducing the GAIN control. 4265.DOC020102 2-46 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 2.3.1.8 Search and Rescue Transponder SART ON/OFF The SART functionality is only working for X-band. Operator controls Task The SART ON/OFF does not activate the ships SART facility. It changes receiver bandwidth to improve SART detection by this Radar. Information about the SART transponder The purpose of the SART is to trigger a secondary alarm when search and rescue units are searching for a life raft/lifeboat in distress. The SART will help the units to pinpoint exactly where the distressed boats are located in a large area. This is done with the help of the Radar on the search ship or helicopter. When the SART is interrogated (hit) by a Radar signal, it will immediately start to transmit a number of sweeps covering the complete maritime 3 cm Radars. These sweeps are detected on the Radar screen and used to navigate directly towards the distressed life raft. The maximum detectable distance to a ship will normally be about 10 NM or approximately 30 NM to a helicopter, depending on the helicopters altitude. The transponder will not give any alarms further away than this. How is this situation displayed on the Radar?

This situation appears automatically on the Radar video. The echo display on the Radar video depends on the distance of the transponder from your own ship and can be interpreted as follows.

If there is no pulse width toggle field, this indicates that it is not available for the range currently being used. Operator controls Task Selecting this toggle field allows the pulse length to be switched e.g. from short pulse to medium pulse and vice versa to optimize target discrimination with respect to the selected range. Use of a longer pulse improves target reception but, at the same time, increases clutter returns. When using longer pulses it may be difficult to differentiate very close targets. When a shorter pulse is used, reception of some weaker targets will decrease, but clutter will also decrease, resulting in better target detection. The available pulse width selections for the Radar displays and the Radar MTRs are illustrated in Table 2-7.

MAPS are normally produced for the Radar video in use. For example, they can be saved under the name of a sea area which corresponds to the Radar video in use. If the ship enters this sea area again, the associated map can be loaded. A map is formed by adding true mark symbols, navigational lines, route lines and index lines to the PPI at points selected by the operator or at areas of interest. The symbols can be used to mark navigation channels, safety zones, buoys or other points of interest. Valid position information is required to create maps. Position information is transferred from a position receiver

(e.g. GPS) to the Radar as of data telegram. The MAP MENU cannot be called up without valid position information. A map can be made up of any combination of 100 TRUE MARKS, 250 NAV/ROUTE LINES and 50 INDEX LINES. When a map is created, it is placed in temporary storage. It can then be saved in permanent storage. Each map can be assigned with a label made up of 8 alpha numeric characters. Operator controls Task After pressing the soft button the MAIN MAP MENU appears in the functions display.

This function allows the potential collision point (PCP) or the closest point of approach (CPA) for acquired targets to be indicated by a circular symbol at the PPI. Acquired targets can be displayed with relative or true vectors. TRUE allows the PCPs for all acquired targets to be displayed at the PPI. RELATIVE allows the CPAs for all acquired targets to be displayed on the PPI. Both types of display support prompt assessment of close range situations. Vector mode TRUE - Potential Collision Points (PCP) -

Potential collision points (PCP) provide a rapid overview of current and potential collision danger. Assessment:

There is a current collision danger if a PCP lies on your own ships head up line. There is a potential collision danger if your own ship changes its current course such that a PCP that did not previously lie on the ships head up line will now lie on that line. Potential collision points are calculated after target acquisition. Every target is normally marked with one PCP, which appears as a small circle. Under certain circumstances, it is possible that a target is marked by 2 PCPs. In such a situation, both PCPs are applicable and must be taken into account when viewing the Radar image. PCPs do not take into account the dimensions of the own ship or the target. Target acquisition must first be carried out. 4265.DOC020102 2-132 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Operator controls Task Step 1 Switch over to TM(T) (recommended).

If the fixed target is lost the Radar generates a LOST REFERENCE TARGET alarm. Own ships speed values cannot be evaluated. The Radar can support this by accepting one echo that the user knows is geostationary. After 2 minutes, the Radar accuracy calculates the ships ground velocity until the track is lost or new echoes chosen. Accuracy of the calculated ground speed depends on the selected target and the environmental conditions and may deviate from the real speed of the target. Please monitor the value carefully. Collision avoidance data (relative speed, CPA/TCPA, BCR/BCT) of AIS targets cannot be calculated with a reference target speed.

Edition July 2015 2-161 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 2.5.5 Association Settings The target association combines the information of targets which are close together to one single target. Target association is performed between ARPA and AIS targets as well as ARPA targets tracked at different workstations. Targets are associated, if the position, speed, and course of the targets are within the pre-defined association limits. The Radar supports several association profiles for navigation under different conditions (see SYNAPSIS SYSTEM MANUAL (Document No. 4279 chapter 4.1)). By switching on the Radar function TGT ASSOC ON, both AIS and Target information of acquired targets are associated if the association criteria are fulfilled. The ASSOCIATION SETTINGS menu is organized by factory predefined profiles. 2.5.5.1 Target Type Hierarchy The priority selection TARGET TYPE HIERARCHY allows the operator to decide which source is used to calculate collision avoidance data. If AIS is selected and a combined target contains AIS data, the combined target is displayed with position, speed, and course from AIS. If Radar X Band is selected and the combined target contains data from an X-Band ARPA tracker, position, speed, and course from this ARPA tracker is used. Depending on the priority (MODIFY button) selected, the target info display switches over accordingly; AIS or Target. After pressing the AIS soft button AIS targets (sleeping/activated) appear on the PPI if there are AIS targets in the area. The area in which the AIS information is displayed depends on the used AIS FILTer RNG. Sleeping targets are displayed smaller than the activated targets. Sleeping targets can be switched over to activated targets per cursor function or per ACTIVATION RANGE. 4265.DOC020102 2-162 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Operator controls Task Edition July 2015 Step 1 Select the AIS soft button.

The possible tracking zone of all acquired targets can be 0,25 to 20 NM. The operator can define acquisition zones. As soon as a target enters such a zone, it is plotted and tracked by the Radar. If a sleeping AIS target enters an acquisition zone, the target is activated. Despite all the advantages of automatic target acquisition, it may be found:

Certain targets cannot be acquired due to the current weather conditions. Targets cannot be acquired due to the set acquisition zone. Targets cannot be acquired due to their size and material. The target information is displayed when striking the TGT INFO soft key. ARPA ZONES in a INS System. An ARPA ZONE created on a MFC console displays in continuous line and yellow color (active ARPA ZONE). Targets arriving this ARPA ZONE will be acquired on this MFC console. The same ARPA ZONE displays on the other MFC in yellow color and dashed lines (passive ARPA ZONE).

The target is automatically acquired and tracked. The ACQUISITION ZONE is considered to be an essential aid and information source for assessing the situation. The decision as to whether a short-

range situation will develop from this information must be made by the navigator himself!

If an acquired target enters this GUARD ZONE, the Radar outputs a Guard Zone Alarm. The GUARD ZONE and related target acquisition are only intended to draw the Radar user attention to a target. The decision as to whether a short- range situation will develop from this information must be made by the navigator himself!

If the user wants to exclude certain areas from automatic acquisition, he can create an EXCLUSION ZONE. In this zone, all Radar returns (video) will be ignored. Within the exclusion zone, no targets are acquired and displayed on the Radar video. The master and navigator are responsible for assessing and considering any possible collision situations that could result from this. 4265.DOC020102 2-168 Edition July 2015 2.6.1.1 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Select ACQUISITION Zone Shape The sequence of operations below can be used to select the acquisition zone form SECTOR.

This function can only be realized via ECDIS in connection with the CMAP Chart Data (vector charts). ECDIS procedure ECDIS allows the operator to send objects (e.g. Depth contour or Buoys) to selected Radars and displays them on the PPI. The interface between Radar and ECDIS is serial and designed according to NMEA 0183. Radar procedure The Radar Function SENC allows the user to adjust (Radar Fix) the object positions of objects transferred between ECDIS and Radar. Transferred lines and objects can be individually switched on and off by the Radar user. Cursor The Radar cursor appears in the ECDIS chart as a second cursor in GREEN color. The ECDIS cursor appears on the Radar PPI as a second cursor in ORANGE color. A route planned on an ECDIS is based on the electronic chart vector format being used on the ECDIS PC. This chart presentation is based on a MERCATOR projection. If a route is created on an ECDIS and send to the Radar, the route will be displayed on the Radar PPI. If the distance between two waypoints is too long the track leg should be drawn as a Great Circle. As the route on the Radar is displayed as a Rhumb line it deviates from the Great Circle presentation. To keep the deviation as small as possible the distance between two waypoints should be maximum 40 nautical miles to approximate it to a series of Rhumb Line tracks.

In this case a Chart appears as chart underlay on the PPI. For this Radar/ECDIS System the complete Chart handling (license, installation and updates) has to be done at the ECDIS. An accurate position sensor is required to make sure that the chart underlay and Radar images agree with each other. Depending on the range of the Radar and the scale of chart underlay being used, GPS is usually suitable for mid- to long- ranges, while DGPS is suitable for close ranges and large- scale display (e.g. > 1:10.000). In general, the more accurate and reliable the position fixing system, the more accurate and reliable is the combined Radar and chart underlay. It has to be realized that for the position obtained from the Radar image to be in precise agreement with the GPS, the chart data must be referenced to WGS 84. This is a requirement for ECDIS. RNC charts are prohibited to use with Chart Radar. 4265.DOC020102 2-206 Edition July 2015 2.8.1 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Chart After pressing the CHART soft button the chart appears as a chart underlay on the PPI. In this case the Radar function SENC will be blocked. The chart scaling effect is combined with the range scale effect.

The trial manoeuvre scenario takes place in real time. The trial manoeuvre can be used for all ship categories. When the trial manoeuvre function is on, a large letter T flashes at the bottom of the PPI. This is to remind the operator that the current Radar video and plotting data is not the true navigational situation. The user can return to normal Radar operation by clicking on TRIAL again. When changing course or testing a proposed course, the trial heading is indicated in white and by a dashed line originating from own ship. The trial radius is indicated as a thicker white line originating from own ship. Use realistic DELAY and RADIUS values which describe to own ships dynamic characteristics in the trial functionality in terms of turning performance and rate of change of velocity. If True vectors are selected, your own ships vector will reflect any set and drift inputs (course made good). Target data (SPD, CSE, ID, CPA, TCPA) that is being plotted is still shown in the actual TRIAL MANOEUVRE readout. The best trial manoeuvre information is provided by using relative motion and sea stabilization (water tracking). During a trial manoeuvre, there are no restrictions on the operation for the Radar user interface. Edition July 2015 2-213 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Sea Scout and ARPA Trial Manoeuvre Using the Sea Scout (chapter 2.10) function it is possible and helpful to use the ARPA Trial Manoeuvre as a second function. The operator can see the No- Go Areas and find the gap between these areas per trial manoeuver. Alarms and warnings during the trial manoeuvre:

Real alarms The ARPA tracking system continues running in the background. If there is a real close range situation (target enters the CPA/TCPA zone limits), an automatic alarm is generated. The target symbol flashes and a corresponding alert text message appear in the alarm display. Temporary alarms If a close range situation occurs during the trial manoeuvre, the target symbols flash. Operator controls Task Step 1 Open the TRIAL function. Step 2 Switch the SYM status to ON. All symbols (EBLs, VRMs, PILs, ARPA zones, MAPs) are shown on the PPI. Step 3 Switch the vector display into REL mode. 4265.DOC020102 2-214 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Operator controls Task Step 4 Press the INACTIVE button for changing to the ACTIVE situation.

Using the trackball the desired parameter value changes. Follow the display changes. Press the left trackball button again, the process stops. The readouts show acquired targets (ID no.) with their CPA/TCPA values. The readouts are classified in TRIAL DATA and ACTUAL DATA. The TRIAL DATA readout displays the possible close range situation during the TRIAL manoeuvre in combination with the acquired targets (ID no.). The ACTUAL DATA readout displays the actual situation in combination with the acquired targets (ID no.). Step 5 Press the CNTDWN button for starting the countdown. The DELAY time counts down in second steps (DELAY time 00.00). The possible close range situation has to be completed by a relevant manoeuvre before the DELAY time is executed. Exit the TRIAL MANOEUVRE by pressing the EXIT button. Result:

When a trial manoeuvre is added, the trial course (CSE) identifies the new heading and is able to show potential collision points. Trial speed (SPD) changes the potential collision points and the higher the selected speed the more PCPs will be in the vicinity of the tracked ships. A trial manoeuvre and PCPs are a way to view the advantages of a change in speed. The time changes (DELAY) allow the operator to check the trial course history in the future situation. The countdown (CNTDWN) allows the operator to observe the possible close range situation in real time.

Edition July 2015 2-233 4265.DOC020102 3 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Theory of Operation This chapter gives additional information about Radar operation and functions. It explains terminology and describes a number of effects which have influence on Radar performance and have to be considered by the operator. A Radar uses a very high frequency radio wave (microwave) which has similar properties to those of light regarding straightness and uniform velocity. The Radar antenna radiates the fan shape fine microwave (fan beam) to the target just as a search light throws the light beam to the target, and the reflected microwave from the target returns to the antenna. The Radar does not use an continuous wave but radiates the wave for a very short period (approx. 10-6 to 10-8 second .... called pulse) to measure the time from when the wave is radiated till the reflected wave returns to the antenna. In addition, with rotation of the antenna at a constant speed, the fan shape radio wave radiated from the antenna scans around 360 - with the antenna at its center - in order to detect the object. 3.1 Radar Plotting Terminology Bearing (AZIMUTH) The horizontal direction of one point from another point, expressed as the angle in the horizontal plane between a reference line and the horizontal projection of the line joining the two points. TRUE Bearing > Reference is true north RELATIVE Bearing > Reference is own ships heading Target Speed TRUE > Actual speed made good by target. RELATIVE > In relation to own ships movement Target Course TRUE > Direction of target movement referenced to true north. RELATIVE > Direction of target movement referenced to own ship bow. Closest Point of Approach (CPA) Edition July 2015 3-1 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual The point at which a target will be closest to own ship Time to Closest Point of Approach (TCPA) The time remaining to CPA, based on current own ship speed. Potential Collision Point (PCP) The point at which a collision would take place if the target vessel maintains present course and speed, and own ship maintains present speed and if own ship were to choose to steer a collision course now. Radar Video presentation Relative Motion (RM) In this mode, the Radar shows the motion of a target relative to the motion of own ship, own ship is fixed on the screen. Targets move on the screen. Relative Motion can be with True Trails RM (T) or Relative Trails RM (R) True Motion (TM) In this mode, the actual or true motion of a target and own ship, i.e. land masses or non- moving targets are fixed on the screen while targets with actual motion and own ship move on the screen (similar to plotting chart). True Motion can be with True Trails TM (T) or Relative Trails TM (R). 4265.DOC020102 3-2 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Figure 3-1 Relative Motion (T) / Relative Motion (R) Edition July 2015 3-3 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Figure 3-2 True Motion (T) / True Motion (R) 4265.DOC020102 3-4 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Vectors Relative Vector Line drawn on screen to indicate calculated relative course and speed of targets.

Edition July 2015 3-5 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.2 3.2.1 Radar Pattern Interpretation The Radar displays a chart- like picture (PPI) on TFT under normal conditions. Under certain conditions, however, various false echoes are generated, and small targets are hidden by rain, snow or sea waves. To correctly interpret tar-

gets and patterns which appear on the TFT requires considerable experience. Compare patterns that appear on the Radar image to the actual topography to acquire experience as far as possible. Range The detectable range depends on the antenna height and height of targets. Sometimes, however, the Radar detectable range is longer due to refraction of the wave beam according to weather conditions. The radio wave is obstructed by mountains and hills, forming a shadow behind these objects. H1 D = 2 ( H1 + H2) H2 D[Nm]

H[m]

Figure 3-3 Detectable Range Examples:

A big ship with 25 m antenna high can detect a 4 m high small ship in up to 14 NM distance. A big ship with 25 m antenna high can detect a 25 m high ship in up to 20 NM. A big ship with 25 m antenna height can detect a 100 m high coast in up to 30 NM. 4265.DOC020102 3-6 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Sea Clutter, Rain Clutter The Radar wave is reflected by waves, clouds, rain and snow. This is displayed as a bright noise which clutters the Radar Video and may hide targets When this happens, adjust GAIN, SEA (sea clutter), RAIN (rain and snow clutter) controls to assist in the detection of targets. Then adjust FTC. Take note that ordinary visible targets cannot be seen in heavy rain and snow

In that unlikely case slowly moving spotters or spirals can be observed on the PPI. The Radar processing removes these interferences automatically if IR ON is activated (Figure 3-5). However that filter can have a negative effect when detecting SARTs. IR OFF IR ON Figure 3-5 Interference selection IR ON / OFF 4265.DOC020102 3-8 Edition July 2015 3.2.1.3 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Side Lobe Effect In short ranges, not only the main lobe of the Radar is reflected by ships nearby but in some cases also the side lobes are reflected. This leads to false echoes, which are all at same distance, but different bearings. Multiple reception effect. If a strong echo reflected from a large object at short range is reflected several times between the object and own ship, false echoes are displayed at positions of 1, 2, 3 or more times the distance of the actual position. A is the actual echo, B and C are false echoes, and D and E are side lobe echoes (Figure 3-6). These echoes can easily be identified because these echoes can be reduced by adjustment of GAIN, SEA controls. Side lobe effects D A E Multiple reception B C A Main lobe Side lobe Side lobe Figure 3-6 Side lobe and multiple reception false echoes Edition July 2015 3-9 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.2.1.4 Second trace false echo The second trace false echo appears when the signal is received at the next pulse repetition period after it was reflected by a high mountain or similar object in long distance. Therefore, the position in which it appears is identified by subtracting distance corresponding to the pulse repetition interval from the actual distance. Assuming the pulse period is 1000 s and the range scale is adjusted tor 12 NM, the pulse reflected from a target 80 NM away returns after 1000 s. Targets lying at a distance of beyond (80 NM + 12 NM=) 92 NM, therefore, can generate second trace false echoes. A target in 83 NM distance may generate an echo on the Radar display at 3 NM

(Figure 3-7). Transmit pulse 1 Transmit pulse 2 Second trace false echo Range scale 12 NM Pulse period 1/pulse repetition frequency with 1000/s approx. 80 NM Range scale 3 NM Echo from transmit pulse 1 Figure 3-7 Second Trace False Echo Effect 4265.DOC020102 3-10 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual It often appears that the radio wave propagation is abnormal (duct effect), when the object is a very large mountain. If the signal reception level, however, is small and the transmitted pulse intervals are slightly changed, then a long cloudy form echo appears as shown in the figure, and can easily be identified. If it is difficult to identify, reduce the receiver gain (GAIN) slightly. In rare cases, the guard ring alarm goes off. In this case, check and observe the video echoes, and reduce the receiver gain, and in case of medium range scale (3, 6, 12 Nm) switch to LONG PULSE or to 24 Nm range scale (Figure 3-9).

This leads to wrong measurements in long distances.

The actual speed and course of own ship and two targets are such that target 1 will eventually collide with own ship, and the target 2 will pass well behind own ship. In TRUE vector mode, tracked targets which are standing still (such as target 3) do not display a vector. Figure 3-10 True Vector Mode Edition July 2015 3-13 1 2 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.3.2 Relative Vector Mode Relative vector mode shows how targets move in relation to own ship. All ships that have relative vectors pointing to my own ship are dangerous targets. Figure 3-11 Relative Vector Mode When the same situation is displayed in RELATIVE vector mode, target 1 is gradually closing with own ship and it is apparent that target 2 indicates no threat as long as neither own ship nor target changed their headings. The stationary target 3 does not move at all. Its relative vector is exactly opposite to own ships vector. 4265.DOC020102 3-14 Edition July 2015 3.4 Synapsis Radar with Nautoscan NX Pedestal Operator Manual Automatic Radar Plotting Aid (ARPA) The purpose of an Automatic Radar Plotting Aid (ARPA) is to interpret Radar information continuously and to display the results so that watch officers may quickly assess and react to potential danger. The performance specification of the International Maritime Organization (IMO) requires the ARPA plotting reliability to be as good as manual plotting techniques. The NSC meets and exceeds these minimum requirements to provide a greater margin of safety. The first requirement of safety is to maintain surveillance of traffic and navigation hazards. The ARPA will plot up to 40 automatically and 40 manually acquired (Plot) targets. For any targets being plotted, the ARPA continuously displays vectors indicating speed and course. Based on preset conditions the ARPA determines if the possibility for collision exists. When a potentially dangerous target is detected, warnings are given and information detailed on the target is displayed. If the watch officer determines that an avoidance maneuver is required, the ARPA trial maneuver mode can assist in the planning. When a maneuver is actually made, the ARPA continuously displays the effect on all plotted targets during and after the course change. Edition July 2015 3-15 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.4.1 3.4.1.1 Sensor Errors The performance of ARPA depends on the quality of the sensor information which is processed. The Radar is the sensor which measures target range and bearing relative to own ship. The gyro compass measures the heading of the own ship relative to north. The speed log measures the motion of own ship relative to the water or bottom. Gyro Compass A precise Gyro Compass heading is an important condition for accurate target tracking and ARPA information. The Radar user should be aware that Gyro Compasses may have errors (speed error and acceleration error). These errors can degrade the accuracy of target results (ARPA INFO). Raytheon Gyro Compasses have automatic error correction and supply true heading to Radars. This may not be the case for other Gyro Compass models. If Gyro Compass heading input is interrupted, the Radar will give alarm. 3.4.1.2 Speed Log A precise speed input from the log is an important condition for accurate target tracking and ARPA INFO. The Radar user should be aware that speed outputs of logs may be temporarily unstable for various reasons. This may degrade the accuracy tracking results (ARPA INFO). If speed input is interrupted, the Radar will give alarm. 3.4.1.3 Plotting Plotting is started by positioning the trackball cursor over the desired target echo. When the soft button is pressed the Radar acquires the target. When a target becomes too weak or too large and is identified by the ARPA as a LOST TARGET, two options are available:

(1) CANCEL Option: As a warning, a flashing symbol marks the last position of the target. The ARPA attempts the target by increasing the window size. It coasts for five scans (antenna rotations) and if the target is not located in the enlarged window, the plot is cancelled. 4265.DOC020102 3-16 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual

(2) COAST Option: The lost target data is not automatically cancelled but rather is coasted and the flashing LOST TARGET symbol marks the last position of the target. To delete the LOST TARGET symbol, track, and target data, a manual cancel operation must be done. CAUTION If the target gets close to another target, the two targets cannot be discriminated and tracking may resume on these signals. The operator should investigate all ARPA Alarms. If a plot acquisition is attempted on a target close to another plot, the new plot will be refused. To determine accurate ARPA results, a number of past positions have to be recorded. After acquiring a close target, the processor takes about a minute to record enough position data to get a good, accurate speed. More time could be required for targets more than eight miles away. Edition July 2015 For accurate target data, accurate own ships course and speed are required, particularly during course changes. Sensor errors in own ships course and speed will cause equal errors in target data. Manual speed entries can be used, but for best performance an accurate speed log is recommended. A Ground Reference mode is provided to improve speed measurements. A small, fixed, stable target is plotted to give a zero speed reference. Target positions and own ships position may be referred to the Reference Target. The use of a suitable reference target will improve motion stabilization and target data. 3-17 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.4.2 Collision Assessment (Surveillance) Once the true velocities of own ship and targets are established (within one minute of acquisition), it is valid to interpret displayed information for collision assessment. TRUE and RELATIVE VECTORS are available to present target velocities. 3.4.2.1 3.4.2.2 The NSC provides two additional surveillance features to aid in rapid assessment of collisions potential in congested situations. When displaying TRUE VECTORS, the operator may choose to display Potential Collision Points

(PCPs). The appearance of one or more of these symbols, on or near own ships heading line, immediately signals collision potential. When displaying RELATIVE VECTORS, the operator may choose to display all CPAs within the set CPA limit, plus one mile of own ship whose TCPA is less than 30 minutes. The appearance of one or more of these symbols near own ships current position immediately signals collisions potential. Accuracy of Collision Assessment The position of PCP and CPA are the key parameter in collision assessment and of vital importance. Both are calculated from knowledge of present position and velocities of targets and own ship. Displaying of CPAs CPA is the Closest Point of Approach for any target vessel if both the target vessel and own ship maintain course and speed. The calculated CPA will match the actual CPA only if the present course and speed of the target vessel has been maintained long enough for the target velocity filters to settle. The ARPA specification allows up to three minutes for this purpose. The Radar accomplishes this in one minute. Furthermore, if own ships speed-log has no smoothing or delay in its readings, the NSC will produce an accurate CPA even as own ship comes to a new course and/or speed (target not maneuvering). CPA and TCPA are calculated for all targets, once for each revolution of the Radar antenna (approximately two seconds for Raytheon Radars). CPA symbols will be displayed if:

(1) the operator selects the CPA/PCP display button on the collisions assessment menu page and 4265.DOC020102 3-18 Edition July 2015 Synapsis Radar with Nautoscan NX Pedestal Operator Manual

(2) RELATIVE vector mode is selected and

(3) the CPA symbols are located within the bearing scale and

(4) display is stabilized and

(5) symbol display state is ON and

(6) ARPA DATA display state is ON Edition July 2015 3-19 4265.DOC020102 Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.5 Keep the Following Points in Mind when Operating the NAUTOSCAN NX Radar Video The Radar video display area is updated from a memory. The memory is updated as the antenna scans. The Radar picture is signal processed from previous scan of the antenna. This process is called scan-to scan correlation. Three scans are required to integrate a target to full brightness. It should be noted that while in head up, the scan integration process is removed and all targets including clutter are displayed at full brightness. Anti-clutter filter ON/OFF In case of heavy clutter developing on the Radar video, the NSC computer creates a profile of the echo. Within this profile, the received echoes are monitored for a certain period (Scan-to-scan method). Irregular echoes are suppressed on the Radar video. Regular echoes are indicated on the Radar video. If Anti-clutter filter is ON, the following effect can happen:

Fast acquired targets (> 100KN) can be lost. Moved acquired targets can be displayed smaller on the PPI. Sensitivity Controls When the sensitivity controls are used, the operator must wait for three scans to see the final result. The Radar picture will build until targets are displayed at a bright level. Receiver noise and in most cases, clutter, will not be integrated and will appear dim when the controls are properly set. Adjust the controls in small increments. Radar Detectability The processing of three scans of Radar data results in greater Radar detectability. Targets which otherwise would be in noise now stand out clearly. Greater Radar detectability could occasionally cause reflections and other undesired echoes to appear as strong returns. Use the sensitivity controls to achieve a suitable presentation. Best Clutter/Interface Rejection The best clutter/interference rejection will occur when accurate speed

(log) and gyro information is used to stabilize the Radar display. Use the Sea and Rain controls to suppress clutter and leave targets at a bright level. 4265.DOC020102 3-20 Edition July 2015 Synapsis Radar With Nautoscan N Pedestal Operator Manual 4 Index Additional documentations ...................
