Summary to detect SART response
1. Use range scale of 6 or 12 nm as the spacing between the SART responses is about
0.6 nm (1125 m) to distinguish the SART.
2. Turn off the A/C AUTO function.
3. Turn off the Interference Rejector.
General remarks on receiving SART
Radar range scale
When looking for a SART it is preferable to use either the 6 or 12 nautical mile range scale.
This is because the total displayed length of the SART response of 12 (or 24) dots may
extend approximately 9.5 nautical miles beyond the position of the SART and it is neces-
sary to see a number of response dots to distinguish the SART from other responses.
SART range errors
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 mush 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
meters beyond the true position.
