1.4.7 RADAR Setting for SART Detection (X-Band only)
The information needed for reliable detection of SART's is described in IMO Circular 161. The content of
that paper is reproduced on the following pages.
ANNEX
OPERATION OF MARINE RADAR FOR SART DETECTION
WARNING: A SART will only respond to an X-Band (3 cm) radar. It will not be seen on
an S-Band (10 cm) radar.
Introduction
l. A Search and Rescue Transponder (SART) may be triggered by any X-Band (3 cm)
radar within a range of approximately 8 n.miles. Each radar pulse received causes it to
transmit a response which is swept repetitively across the complete radar frequency band.
When interrogated, it first sweeps rapidly (0.4 μsec) through the band before beginning a
relatively slow sweep (7.5 μsec) through the band back to the starting frequency. This
process is repeated for a total of twelve complete cycles. At some point in each sweep, the
SART frequency will match that of the interrogating radar and be within the pass band of
the radar receiver. If the SART is within range, the frequency match during each of the 12
slow sweeps will produce a response on the radar display, thus a line of 12 dots equally
spaced by about 0.64 n.miles will be shown.
2. When the range to the SART is reduced to about 1 n.mile, the radar display may show
also the 12 responses generated during the fast sweeps. These additional dot responses,
which also are equally spaced by 0.64 n.miles, will be interspersed with the original line
of 12 dots. They will appear slightly weaker and smaller than the original dots.
RADAR Range Scale
3. When looking for a SART it is preferable to use either the 6 or 12 n.mile range scale.
This is because the total displayed length of the SART response of 12 (or 24) dots may
extend approximately 9.5 n.miles beyond the position of the SART and it is necessary to
see a number of response dots to distinguish the SART from other responses.
SART Range Errors
4. When responses from only the 12 low frequency sweeps are visible (when the SART
is at a range greater than about 1 n.mile), the position at which the first dot is displayed
may be as much as 0.64 n.mile beyond the true position of the SART. When the range
closes so that the fast sweep responses are seen also, the first of these will be no more than
150 metres beyond the true position.
RADAR Bandwidth
5. This is normally matched to the radar pulse length and is usually switched with the
range scale and the associated pulse length. Narrow bandwidths of 3-5 MHz are used with
long pulses on long range scales and wide bandwidths of 10-25 MHz with short pulses on
short ranges.
6. A radar bandwidth of less than 5 MHz will attenuate the SART signal slightly, so it
is preferable to use a medium bandwidth to ensure optimum detection of the SART. The
RADAR Operating Manual should be consulted about the particular radar parameters and
bandwidth selection.
Note about item 6: The bandwidth of the radar is not less than 5 MHz. Therefore, the setting described here is not necessary
