Operator Manual Raytheon Marine GmbHGermanyRNSC 18RADAR2−25 3748DOC020102Edition: 14.JAN.20052.3.1 Sensitivity controls2.3.1.1 Gain and clutter processingThe NSC uses a digital video processing technique called Scan to Scanintegration or field processing. This process requires 3 complete antennarotations 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 mediumbrightness and on the third scan, it appears at full brightness. As long as thetarget is present, it will appear at full brightness. If the target fades in and out, then it will remain on the screen, dropping from fullbrightness to medium and back to full brightness. If the target is lost altogether, then it will take three scans before it completelydisappears.Understanding this 3 scan integration is crucial for operation of the Gain, Seaand Rain clutter controls, because if an adjustment is made to any of thesecontrols, it requires 3 complete scans to properly observe the results of theadjustment. The same applies if a radar target is used as a tuning indicator whenmanually tuning the radar.2.3.1.2 TUNEMANual TUNEThe tune function uses the trackball to control tuning of the receiver frequency tomatch that of the transmitter. The tuning should be adjusted on the medium orlong range scales (6 NM or higher) that show radar returns. For a preliminary manual setting: Use the trackball to place the cursor on the TUNE slider then press the Lefttrackball button. Rotate the trackball for maximum deflection of the slider. As this setting must be averaged over a complete antenna revolution, a peakdetector is included for operator convenience.
Operator Manual2−263748DOC020102 Edition: 14.JAN.2005The tip of the tuning bar (yellow color) remains at the peak signal detectedduring one complete revolution of the antenna.NOTEBear 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 magnetroncharacteristics. As a result of this, the receiver tuning will change during thistime and a final tuning adjustment should be made after approximately thirty(30) minutes of operation. The tuning should also be checked at four−hourlyintervals thereafter.AUTO TUNE (only available in Master mode) When auto tuning is activated, manual tuning is not available. The slider symbolis hidden and the tuning bar color changes to yellow.Auto tune is only available if the NSC radar is working in Master mode.NOTEWith automatic receiver adjustment, the tendency indicator adjusts itself tothe maximum value.−If the magnetron is at the end of its service life and the transmission spectrum has become abnormal, select manual tuning.
Step 1Step 2 Step 1Operator Manual Raytheon Marine GmbHGermanyRNSC 18RADAR2−27 3748DOC020102Edition: 14.JAN.20052.3.1.3 GAINThe 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 againstbackground noise. If GAIN is set too low, weak or distant targets could bemissed. Excessive gain increases background noise and could make targetdetection more difficult. A gain slider is provided to indicate the GAIN controlsetting. Once the GAIN control has been set, it will automatically maintain the samesetting for all ranges. It is not necessary to readjust whenever a new range scaleis 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.2.3.1.4 SEAStep 1Select MANual modeStep 2The Sea control is used to suppress radar returns which are the result of radarsignals reflected from waves. This effect is commonly known as sea clutter.The effects of sea clutter are greater (more reflected energy) at close range andvary with wave height and wind.It should also be noted that sea clutter is reduced on the leeward side of the shipas the retreating wave fronts do not provide as many radar returns as oncomingwaves.Small targets (buoys etc.) often return nearly the same energy as do the wavesand can therefore be lost in the clutter. However, since sea clutter is random innature, the gain and clutter processing circuitry together with the SEA controlallow the operator to reduce the sea returns to a light background speckle at lowbrightness level while maintaining targets in the sea clutter at full brightness.
Operator Manual2−283748DOC020102 Edition: 14.JAN.2005The effect of the Sea control is at its greatest at short range. Its effect reducesprogressively as the range increases. At a range determined by the height of theradar antenna above the water (and other factors), the effect of the SEAcontrol ceases altogether. This is typically about 8−10nm.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 toobserve 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 notethat if the Sea Clutter control is adjusted to completely remove all clutter, thensome targets may not be detected.NOTEThe NSC uses gyro and speed information as part of the clutter removalprocess. It is therefore highly recommended that you use gyro stabilizationand ensure that the manual speed or speed log input is accurate.In heavy wind driven seas where more sea clutter appears on the windward sideof the ship, a slight amount of FTC can balance the clutter (see chapter 2.3.1.6)Then adjust the SEA control to reduce sea clutter. If too much SEA is appliedduring periods of light clutter, then a band of noise could appear on the edges ofthe sea clutter.

This effect is commonly known as rain clutter. As with sea clutter, the rain cluttertends to mask small targets (or large targets if the rain is intense). When heavy rain is falling in the vicinity of the operator’s ship (up to 6−10 nm)and the resulting rain clutter is obscuring nearby targets, then the rain rate slidershould 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 speckleat the dim level. This setting will reduce the rain returns and will have little effecton strong constant target video returns. Weaker targets (usually appear whererain returns are less intense) may be suppressed along with the rain. Most of these weaker targets can be restored by making an FTC adjustment (see chapter 2.3.1.6).
Step 1Step 2Step 1Operator Manual2−303748DOC020102 Edition: 14.JAN.20052.3.1.6 Filtering rain clouds FTCStep 1Select MANual modeStep 2FTC is responsible for differentiation or filtering of rain clouds. Advance the FTCcontrol slowly (remember the 3 scans) until only the leading edges of the rain clutterare visible. As the FTC  is increased, weaker returns will reappear. Stronger returnswill begin to reduce in the visible area. The best setting will be a balance betweenrestoration of weaker returns and adequate size of the stronger returns.Use the trackball to place the cursor on the slider then press the upper trackball.Rotate the trackball to increase or decrease the amount of FTC. Adjusting the FTC will also reduce the land echoes and thin out larger targets. With FTC on and in a light sea, it is possible to overcompensate with the SEAcontrol; if so, with FTC ON a false noise ring may be displayed.Too much FTC will shorten or delete RACON responses. 2.3.1.7 CFAR Step 1AUTO When AUTO is activated, the slider symbols for SEA, RAIN and FTC are hiddenand the bar color changes to yellow.This AUTO mode activates the CFAR (Constant Fault Alarm Rate) functionality.CFAR describes a control algorithm, which uses the evaluation of echoes tocalculate statistical average values for SEA, RAIN and FTC.These average values are used for optimization of the radar video. NOTEUse of CFAR simplifies radar video optimization. However, depending onthe weather conditions misinterpretations are possible. In case of doubt, switch to MANUAL compensation for SEA, RAIN andFTC to clarify the situation. RACONs are best seen in MANUAL.

It changes receiverbandwidth to improve SART detection by this radar.Information about the SART transponderThe purpose of the SART is to trigger a secondary alarm when search andrescue units are searching for a life raft/lifeboat in distress. The SART will helpthe units to pinpoint exactly where the distressed boats are located in a largearea. 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 totransmit a number of sweeps covering the complete maritime 3 cm radar band.These sweeps are detected on the radar screen and used to navigate directlytowards the distressed life raft, for details on radar display.The maximum distance to a ship will normally be about 10 NM or approximately 30 nm to a helicopter, depending on the helicopter’s altitude. The transponderwill not give any alarms further away than this.How is this situation displayed on the NSC Radar?This situation appears automatically in the radar video. The echo display in the radar video depends on the distance of the transponderfrom your own ship and can be interpreted as follows. Figure: 2−15 SART transponder < 0.2 NM

If there is no pulse width toggle field,this indicates that it is not available for the range currently being used.Selecting this toggle field allows the pulse length to be switched e.g. from shortpulse to medium pulse and vice versa to optimize target discrimination withrespect to the selected range.NOTEUse of a longer pulse improves target reception but, at the same time,increases clutter returns.When a shorter pulse is used, reception of some weaker targets willdecrease, but clutter will also decrease, resulting in better target detection.The available pulse width selections for the NSC display are illustrated inFigure: 2−18. SHORT pulse = 0.08µsMED1 pulse = 0.3µsMED2  pulse = 0.6µsLONG pulse  = 1.2µs10Kw transceiver6 ft. antennaInformationA longer pulse width means;more power, stronger targets returns but also more disturbances.Long pulses are necessary in high ranges to detect small targets more effectively.Figure: 2−18 NSC pulse width
