2.3.1.8 Search and Rescue Transponder SART ON/OFF
The SART functionality is only working for X-band.
Operator controls
Task
The SART ON/OFF does not activate the ship’s
SART facility. It changes receiver bandwidth to
improve SART detection by this Radar.
Information about the SART transponder
The purpose of the SART is to trigger a secondary alarm when search and
rescue units are searching for a life raft/lifeboat in distress. The SART will help
the units to pinpoint exactly where the distressed boats are located in a large
area. This is done with the help of the Radar on the search ship or helicopter.
When the SART is interrogated (hit) by a Radar signal, it will immediately start
to transmit a number of sweeps covering the complete maritime 3 cm Radars.
These sweeps are detected on the Radar screen and used to navigate directly
towards the distressed life raft. The maximum detectable distance to a ship will
normally be about 10 NM or approximately 30 NM to a helicopter, depending on
the helicopter’s altitude. The transponder will not give any alarms further away
than this.
How is this situation displayed on the Radar?
This situation appears automatically on the Radar video. The echo display on
the Radar video depends on the distance of the transponder from your own
ship and can be interpreted as follows.
