General remarks on receiving SART

SART range errors
When the SART is at a range greater than approximately 1 nm, the first dot is dis-
played at 0.64 nm beyond the true position of the SART. When the range closes so
that the fast sweep responses are seen also, the first range echoes are displayed at
150 m beyond the true position.
Range scale
When you find the SART position, do as follows:
1. Use the RANGE key to set the range scale to 6 nm or 12 nm.
2. Turn off [Int Rejector].
SART display
To display only the SART echo clearly on the radar screen, reduce the tuning on man-
ual mode. The normal radar echoes get weak, however, the SART echoes remain.
Your ship comes close to the SART, the arc for the SART display becomes larger.
Most of the radar screen becomes fuzzy. Adjust the sea clutter and gain to display the
necessary screen.
