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.
The SART position can be displayed on the radar video by setting the radar as follows:

Attention
When the radar is set as in ‡@ to ‡E above to detect the SART signal, the 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 monitoring targets around own ship, checking on own ship's position
and avoidance of stranding.
After end of detecting the SART signal, it is necessary to readjust the radar for
normal navigation.
