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 rescug 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

Attention
a
When the
radar
is set as
in
O
to
@
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 walch
in
order
to
avoid
any
collision
or siranding.
lf two
or
more
sets of
radar
equipment
are
installed
on
own
ship,
use
one set of 9
GHz
band radar
for delection
of the SART
signal
and operate
others
as
normal
radars
f,or
monitoring trargets 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.
