    1.14 Adjusting the Sensitivity The GAIN control adjusts the sensitivity of the receiver. It works in precisely the same manner as the volume control of a broadcast receiver, amplifying the signals received. The proper setting is such that the back- ground noise is just visible on the screen.

  • Page 27: Suppressing Precipitation Clutter, Interference Rejector

    1.16 Suppressing Precipitation Clutter The vertical beamwidth of the scanner is de- signed to see surface targets even when the ship is rolling. However, by this design the unit will also detect rain clutter (rain, snow, or hail) in the same manner as normal tar- gets.

  • Page 28: Measuring The Range, Measuring Bearing

    1.18 Measuring the Range Measuring range by the fixed range rings Use the fixed range rings to obtain a rough estimate of the range to a target. They are concentric solid circles about own ship, or the sweep origin. The number of rings is auto- matically determined by the selected range scale and their interval is displayed at the upper-left position of the screen.

    1.27 Parallel Index Lines Parallel index lines are useful for keeping a constant distance between own ship and a coastline or a partner ship when navigating. The orientation of the index lines is controlled with the EBL rotary control and the intervals between the lines adjusted with the VRM ro- tary control (provided that No.2 VRM is ac- tive).

  • Page 40: Zoom, Markers

    1.29 Zoom The zoom function is useful for enlarging an area of interest as large as twice the normal viewing. This performs the range scale re- duction to a half and the offset at the same time. Zoom can be used on ranges other than 0.125, 72, 96, 120 nm.

  • Page 50: Peformance Monitor

    1.49 Peformance Monitor The performance monitor (PM-30 for FR-1710/1725, PM-50 for 1760DS) provides an effec- tive means of general performance check of a radar installation. It works like a transponder. Installed in the proximity of the radar antenna, it is triggered by part of the transmitted micro- wave energy and sends back a coded signal to the antenna for display on the radar 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.

  • Page 54: General Remarks On Receiving Sart, Showing Sart Marks On The Radar Display

    When the range to the SART is reduced to about 1 nm, the radar display may show also the 12 responses generated during the fast sweeps. These additional dot responses, which also are equally spaced by 0.64 nm, will be interspersed with the original line of 12 dots.

  • Page 55: Racon (radar Beacon)

    Radar side lobes As the SART is approached, side lobes from the radar scanner may show the SART re- sponses as a series of arcs or concentric rings. These can be removed by the use of the anti-clutter sea control although it may be operationally useful to observe the side lobes as they may be easier to detect in clut- ter conditions and also they will confirm that...
