1-1 1.1 What is Radar? The term “RADAR” is an acronym meaning Radio Detection And Ranging. Although the basic principles of radar were developed dur- ing World W ar II, echoes as an aid to naviga- tion is not a new development. 1.2 How Ships Determined Position Before Radar Before the invention of radar , when running in fog near a rugged shore[...]

2-2 2.2 T urning the Radar On/Off Press the [POWER] key to turn the radar on or off. The control panel lights and a timer displays the time remaining for warm up of the mag- netron (the device which produces radar pulses), counting down from 1:30 to 0:01. 2.3 T ransmitting After the power is turned on and the magne- tron has warmed up, STBY (Stand-[...]

2-3 Note1: Availability of a particular display item depends on incoming data. Note2: When Range to W aypoint reaches 0.1 nm, the WPT marker jumps to dead ahead even though a difference may exist between heading and BRG to WPT . Note3: When cross track error exceeds 1 nm on either side, the XTE mark starts blinking. 2.5 Selecting the Range The rang[...]

2-4 Adjusting the A/C SEA control The proper setting of the A/C SEA should be such that the clutter is broken up into small dots, and small targets become distinguish- able. If the control is set too low , targets will be hidden in the clutter , while if it is set too high, both sea clutter and targets will disappear from the display . In most case[...]

2-5 2.10 Erasing the Heading Marker , North Marker The heading marker or north marker (avail- able with gyrocompass connection) may oc- casionally mask a target. T o view the target, you can temporarily erase the heading marker and north marker by pressing and holding down the [GAIN (HM OFF)] control. Release the control to re-display the mark- ers[...]

2-6 2.12 Measuring the Bearing There are two ways to measure the bearing to a target: by the cursor , and by the EBL (Electronic Bearing Line). Measuring bearing by cursor Operate the omnipad to bisect the target with the cursor intersection. The bearing to the target appears at the bottom of the display . Measuring bearing by EBL 1.

T rue motion T rue motion displays own ship and mo[...]

3-3 3.5 Suppressing Radar Interference Radar interference may occur when near an- other shipborne radar operating in the same frequency band as your radar .

4-1 4. F ALSE ECHOES 4.2 Side-lobe Echoes Every time the scanner rotates, some radia- tion escapes on each side of the beam— called “side-lobes.” If a target exists where it can be detected by the side-lobes as well as the main-lobe, the side-lobe echoes may be represented on both sides of the true echo at the same range, as shown in Figure 4[...]

4-2 4.3 Indirect Echoes Indirect echoes may be returned from either a passing ship or returned from a reflecting surface on your own ship, for example, a stack. In both cases, the echo will return from a legitimate contact to the scanner by the same indirect path. The echo will appear on the same bearing of the reflected surface, but at the same ra[...]

4-3 4.5 SART (Search and Rescue T ransponder) A Search and Rescue T ransponder (SART) may be triggered by any X-Band (3 cm) ra- dar within a range of approximately 8 n.miles. Each radar pulse received causes it to trans- mit a response which is swept repetitively across the complete radar frequency band. When interrogated, it first sweeps rapidly ([...]
