NSC 18 RADAR Operator Manual R Raytheon Marine GmbH Germany IMPORTANT NOTICE AND SAFETY INFORMATIONS This Radar is an aid to navigation. Its accuracy can be affected by many factors such as equipment defect, environmental conditions, or improper operation. It is the user’s responsibility to exercise common prudence and navigational judgement at all times.
Operator Manual HIGH VOLTAGE There is absolutely no danger in handling the external controls of the radar while the radar is in operation. In the radar‘s interior, however, are high voltages which are fatally dangerous to anyone careless handling interior components. Be absoluteley sure that the radar power switch is OFF before performing repair work or maintenance . Furthermore, even when the power switch is turned off, a high voltage remains in certain parts of the radar circuits.
NSC 18 RADAR Operator Manual R Raytheon Marine GmbH Germany MICROWAVE RADIATION A short exposure to the microwaves radiated by the radar antenna is harmless. However, avoid prolonged exposure to the microwaves. Never look directly into the wave guide while checking transceiver operation, since microwaves are especially harmful to the eyes. The radiation of microwaves can be checked with a neon tubel . The neon tube will glow in the presence of microwaves. Edition: 14.JAN.

Operator Manual 2.3 DISPLAY OPERATIONS AND INDICATORS This chapter describes the function sections of the NSC display see Figure: 2−14. SHM see chapter 2.3.2.1 Radar video displays, Radar video settings, INFORMATION PANEL, see chapter 2.3.2 see chapter 2.3.3 see chapter 2.3.6 MENU bar, Antenna sensitivity controls, see chapter 2.3.6.6 see chapter 2.3.1. North Marker PPI Radar compass rose with NORTH MARKER Radar video Cursor information in radar video range, see chapter 2.3.
NSC 18 RADAR Operator Manual 2.3.1 Sensitivity controls 2.3.1.1 Gain and clutter processing R Raytheon Marine GmbH Germany The NSC 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.
Operator Manual The tip of the tuning bar (yellow color) remains at the peak signal detected during one complete revolution of the antenna. NOTE 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.
NSC 18 RADAR Operator Manual 2.3.1.3 R Raytheon Marine GmbH Germany 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.
Operator Manual The effect of the Sea control is at its 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 8−10nm. The ideal sea control setting will reduce sea returns to a light speckle.
NSC 18 RADAR Operator Manual 2.3.1.5 Step 2 R Raytheon Marine GmbH Germany RAIN RATE Step 1 Step Step 1 1 Select MANual mode Step 2 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).
Operator Manual 2.3.1.6 Filtering rain clouds FTC Step 1 Step 1 Select MANual mode Step 2 FTC is responsible for differentiation or filtering of rain clouds. 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. The best setting will be a balance between restoration of weaker returns and adequate size of the stronger returns.
NSC 18 RADAR Operator Manual 2.3.1.8 R Raytheon Marine GmbH Germany Search and rescue transponder SART ON/OFF (option) The SART ON/OFF does not activate ownship SART. 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.

Relative trails is the original radar method to view plot history (also with EBL) to quickly see which approach own ship. In Figure: 2−20 the other ships are all heading west (ARPA data). Relative Trails / BCR information is an option for experienced radar operators.
Operator Manual Relative Motion (T) with TRAILS In this case, land masses, buoys, ships at anchor, etc. appear exactly as they are, as stationary objects. Objects in motion, including your own ship, move across the radar video with the correct true speed and course. The trail afterglow displays the track.

The sensor type being used is indicated (e.g. gyro). D Course (CSE) is the true course over ground. The difference between course made good and heading (HDG) is the drift angle commonly referred to as SET. D The speed source defaults to MANUAL when the system is powered up.
Operator Manual AUTO mode Set and drift information is derived from the speed sensor input. If the speed source is lost due to malfunction, the values will be canceled. Select another speed sensor if possible or switch to manual or select Reference Target. MANUAL mode Place the cursor on the toggle field and press and hold the Left button on the trackball. To set MANUAL inputs, use the slider function and the trackball. Release the Left button and press it again.
R NSC 18 RADAR Operator Manual 2.3.6.2 Raytheon Marine GmbH Germany Display and selection of VECTOR and HISTORY TRACK information This information area allows the operator to select TRUE or RELATIVE VECTORS. True vectors show the true course speed of the target and your own ship. Relative vectors show the target’s relative motion compared to your own ship. Your own ship does not have a relative vector.
Operator Manual D PAST POSITION In addition to their symbol, all acquired targets can be given a history track. With the PAST POSITION function switched on, a past position point is set at the target symbol’s position (see Figure: 2−30). The interval between two past positions can be adjusted. Past positions indicate the last completed maneuver of the acquired targets. In absolute (TRUE) view, it is possible to differentiate between changes of course and changes of speed.
NSC 18 RADAR Operator Manual R Raytheon Marine GmbH Germany D TRAILS With this function, all targets located in the acquisition range are given an artificial afterglow (see Figure: 2−31).
