Furuno 1734C manual Racon Radar Beacon, General procedure for detecting Sart response

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.

2.26.3 Racon (Radar Beacon)

A racon is a radar transponder which emits a characteristic signal when triggered by a ship’s radar (usually only the 3 centimeter band). The signal may be emitted on the same frequency as that of the triggering radar, in which case it is superimposed on the ship's radar display automatically.

The racon signal appears on the PPI as a radial line originating at a point just beyond the position of the radar beacon or as a Morse code signal (see figure below) displayed radially from just beyond the beacon.
