……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.
The SART position can be displayed on the radar video by setting the radar as follows:
q
Radar range scale : 6 NM or 12 NM
w
Sea clutter control : Minimum (Most counterclockwise)
e
AUTO SEA function : OFF
r
TUNE control : No tuning (to weaken clutter echoes)
t
Interference rejector (IR) : OFF
y
PROCESS : OFF
●
When the radar is set as in
q
to
y
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.
