2. RADAR OPERATION 2.19 Echo Stretch Normally, the reflected echoes from long range targets appear on the display as weaker and smaller blips even though they are compensated by the radar’s internal circuitry. The echo stretch function magnifies these small blips in all ranges. Two types of echo stretch are available: ES LOW which stretches echoes in bearing direction and ES HIGH which stretches them in both range and bearing directions.
2. RADAR OPERATION 2.20 Echo Averaging The echo average feature, which requires a Model 1800/1900 series network radar, effectively suppresses sea clutter. Echoes received from stable targets such as ships appear on the screen at almost the same position during every rotation of the antenna. On the other hand, unstable echoes such as sea clutter appear at random positions. To distinguish real target echoes from sea clutter, echo average performs scan-to-scan correlation.
2. RADAR OPERATION 2.21 Outputting TLL Data Target position data can be output to units of the network and shown on their plotter screen with the TTL mark ( X ). This function requires position and heading data. 1. Operate the trackball to place the cursor on the target whose position you wish to output. 2. If not displayed, press the [HIDE/SHOW] key to display the radar soft keys. 3. Press the TARGET soft key. 12/LP 3nm H-UP 319.
2. RADAR OPERATION 2.22 Guard Alarm The guard alarm allows the operator to set the desired range and bearing for a guard zone. When ships, islands, landmasses, etc. violate the guard zone, an audio alarm sounds and the offending target blinks to call the operator’s attention. CAUTION • The alarm should not be relied upon as the sole means for detecting possible collision situations.
2. RADAR OPERATION The equipment then searches for targets inside the guard zone to determine guard alarm type. If a target is found inside the guard zone, the guard zone type becomes an “Outward guard alarm,” and any target exiting the guard zone will trigger the audio alarm. If no target is found, the guard zone type becomes an “Inward guard alarm,” and any targets entering the guard zone will trigger the audio alarm. The guard alarm type is shown as G1(G2) IN or G1(G2) OUT.
2. RADAR OPERATION 2.23 Watchman 2.23.1 How watchman works The watchman function periodically transmits radar pulses for one minute to check for targets in a guard zone. If a target is found in the zone, watchman is cancelled, the audio alarm sounds and the radar continues transmitting. If no target is found the radar goes into standby for the number of minutes specified on the RADAR DISPLAY SETUP menu.
2. RADAR OPERATION 2.24 Suppressing Second-trace Echoes In certain situations, echoes from very distance targets may appear as false echoes (second-trace echoes) on the screen. This occurs when the return echo is received one transmission cycle later, or after a next radar pulse has been transmitted.

2. RADAR OPERATION 2.26.5 Setting vector attributes (ARP) What is a vector? A vector is a line extending from a tracked target which shows estimated speed and course of the target. The vector tip shows an estimated position of the target after the selected vector time elapses. It can be useful to extend the vector length (time) in order to evaluate the risk of collision with any target.
2. RADAR OPERATION 2.26.6 Displaying past position (ARP) This ARP can display time-spaced dots (maximum ten dots) marking the past positions of any targets being tracked. You can evaluate a target’s actions by the spacing between dots. Below are examples of dot spacing and target movement.

2. RADAR OPERATION 2.27 Interpreting the Radar Display 2.27.1 General Minimum and maximum ranges Minimum range The minimum range is defined by the shortest distance at which, using a scale of 1.5 or 0.75 nm, a target having an echoing area of 10 m2 is still shown separate from the point representing the antenna position. It is mainly dependent on the pulselength, antenna height, and signal processing such as main bang suppression and digital quantization.
2. RADAR OPERATION Radar resolution There are two important factors in radar resolution (discrimination): bearing resolution and range resolution. Bearing resolution Bearing resolution is the ability of the radar to display the echoes received from two targets, which are at the same range and close together, as separate targets. Bearing resolution is directly proportional to the antenna length, and inversely proportional to the radar's wavelength.
2. RADAR OPERATION 2.27.2 False echoes Occasionally echo signals appear on the screen at positions where there is no target or disappear even if there are targets. False target situations may be recognized, however, if you understand why they are displayed. Typical false echoes are shown below. Multiple echoes Multiple echoes occur when a transmitted pulse returns from a solid object like a large ship, bridge, or breakwater.
2. RADAR OPERATION Virtual image A relatively large target close to your ship may show at two positions on the screen. One of them is the true echo directly reflected by the target and the other is a false echo which is caused by the mirror effect of a large object on or close to your ship as shown in the figure below. If your ship comes close to a large metal bridge, for example, such a false echo may temporarily be seen on the screen.
2. RADAR OPERATION 2.27.3 SART (Search and Rescue Transponder) A Search and Rescue Transponder (SART) may be triggered by any X-Band (3 cm) radar within a range of approximately 8 nm. Each radar pulse received causes it to transmit a response which is swept repetitively across the complete radar frequency band. When interrogated, it first sweeps rapidly (0.4 µs) through the band before beginning a relatively slow sweep (7.5 µs) through the band back to the starting frequency.
2. RADAR OPERATION General procedure for detecting SART response 1. Use the range scale of 6 or 12 nm as the spacing between the SART responses is about 0.6 nm (1125 m) to distinguish the SART. 2. Turn off the automatic clutter suppression (if applicable). 3. Turn off the Interference Rejector.
2. RADAR OPERATION A/C SEA control For optimum range SART detection, this control should be set to the minimum. Care should be exercised as wanted target in sea clutter may be obscured. Note also that in clutter conditions the first few dots of the SART response may not be detectable, irrespective of the setting of the anti-clutter sea control. In this case, the position of the SART may be estimated by measuring 9.5 nm from the furthest dot back towards own ship.

4. VIDEO SOUNDER OPERATION Dual-frequency display The dual-frequency display provides both LF and HF pictures. This display is useful for comparing the same picture with two different sounding frequencies. 0.0 LF HF Dual-frequency display LF picture The sounder uses ultrasonic pulses to detect bottom conditions. The lower the frequency of the pulse, the wider the detection area. Therefore, the low frequency is useful for general detection and judging bottom condition.
4. VIDEO SOUNDER OPERATION Marker-zoom display plus normal sounder display Bottom-zoom display The bottom-zoom display expands bottom and bottom fish echoes by the zoom range selected on the SOUNDER RANGE SETUP menu (see paragraph 5.9.3), and is useful for determining bottom hardness. A bottom displayed with a short echo tail usually means it is a soft, sandy bottom. A long echo tail means a hard bottom.
4. VIDEO SOUNDER OPERATION Bottom-lock display The bottom-lock display provides a compressed normal picture on the right half of the screen and a 10 or 20 feet (3 or 6 meter) wide layer in contact with the bottom is expanded onto the left half of the screen. This mode is useful for discriminating bottom fish from the bottom echo. You may select the bottom lock range from the SOUNDER RANGE SETUP menu. For details, see paragraph 5.9.3.
4. VIDEO SOUNDER OPERATION Bottom discrimination display The bottom discrimination mode displays the bottom echo to help you determine bottom hardness. A bottom displayed with a short echo tail usually means it is a soft, sandy bottom. A long echo tail means a hard bottom. Bottom discrimination display A-scope display (display only) The A-scope display, available in all modes, shows echoes at each transmission with amplitudes and tone proportional to their intensities, on the right 1/10 of the screen.

It works as follows: • The range changes automatically to locate the bottom on the lower half of the screen.
4. VIDEO SOUNDER OPERATION 4.4 Manual Sounder Operation Manual operation is useful for observing fish schools and bottom using a fixed gain setting. The gain, range and range shift functions used together give you the means to select the depth you can see on the screen. The basic range can be thought of as providing a “window” into the water column and range shifting as moving the “window” to the desired depth. 4.4.1 Selecting the manual mode 1. 2. 3. 4. 4.4.
