Page 11: Principle Of Operation
1. PRINCIPLE OF OPERATION 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 War 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... - Page 12 Own ship (radar) (A) Bird's eye view of situation Targets Own ship in center (B) Radar picture of (A) Figure 1-1 How radar works Heading marker Range and bearing of a target, relative to own ship, are readable on the PPI.

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 Transmitting After the power is turned on and the magne- tron has warmed up, STBY (Stand-By) ap-... -
Page 15: Selecting The Range
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. -
Page 16: Adjusting The A/C Rain Control (Reducing Rain Clutter)
Adjusting the A/C SEA control The proper setting of theA/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 . -
Page 17: Erasing The Heading Marker, North Marker
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. To view the target, you can temporarily erase the heading marker and north marker by pressing and holding down the [GAIN (HM OFF)] control. -
Page 18: Measuring The Bearing
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. -

Page 29: False Echoes
Occasionally false echoes appear on the screen at positions where there is no target. In some cases the ef f ects can be reduced or eliminated. The operator should familiarize himself or herself with the appearance and effects of these false echoes, so as not to confuse them with echoes from legitimate contacts. -
Page 30: Indirect Echoes
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. -

4.5 SART (Search and Rescue Transponder) A Search and Rescue Transponder (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. - Page 32 This page is intentionally left blank.
