The SART is a Search and Rescue Transponder that provides location
information to search radars operating in the X-band (9.2 - 9.5 GHz).
Once activated the SART detects the radar signal of the search craft and
sends a series of response pulses to the search radar of the search craft
that causes a series of 12 equally spaced arcs to appear on the radar
display (See Figure 1). The arcs indicate the direction to the SART
location. The rescue craft follows the direction shown and proceeds to
the SART.
To achieve the maximum useful range the SART must be mounted at
least 3.3 feet (1 M) above sea level and the rescue craft antenna must be
50 feet (15 m) above sea level. Increasing the height of the SART
antenna will increase the range. For example, lashing the SART to the
top of a pole or an oar in the survival craft will increase the height and
thus the range.
The International Maritime Organization (IMO) requires all vessels of
more than 300 GRT to carry at least one SART and vessels 500 GRT and
over must carry at least two SARTs.
