DISPLAY OF RADAR TRANSPONDER
(SART)
The SART (Search and rescue Radar Transponder) is a survival device authorized by the
GMDSS (Global Maritime Distress and Safety System), which is used for locating
survivors in case that a distress accident occurs at sea. The SART is designed to operate
in the 9 GHz frequency band. When receiving the 9 GHz radar signal (interrogating
signal) transmitted from the radar equipment on a rescue ship or search aircraft, the
SART transmit a series of response signals to inform the distress position to the rescue
and search party.
Perform the following settings to display SART on the radar screen.
1. Range: 6 NM or 12 NM
2.
[SEA] control: Turning to the minimum position (counterclockwise fully)
3. Automatic sea clutter suppression function: Off
4. Tuning function: Off (for less clutter)
5. IR: Off
6. Processing: Off
Note:

When performing the settings 1 to 6 above to display the SART signal, targets
around own ship will disappear from the radar display. So it is necessary to
exercise full surveillance over the conditions around own ship by visual watch in
order to avoid any collision or stranding.
If two or more sets of radar equipment are installed on own ship, use one set of
9 GHz band radar for detection of the SART signal and operate others as
normal radars for avoiding collision, monitoring targets around own ship, and
checking on own ship's position and avoidance of stranding.
After the detection of SART signal, the radar adjustment is required for general
navigation.
