Suppresses interference by other radars.
Interference received simultaneously from multiple
radars may be difficult to reduce.
Enlarges target echoes, especially small echoes.
Suppress interference, sea clutter and rain clutter be-
fore using echo stretch, to prevent enlargement of
unwanted echoes.
The radar samples echoes with each scan.
Targets that show a large change with each scan are
judged as clutter and are reduced to display only
echoes from legitimate targets.
Discriminates clutter from the radar echo, then reduc-
es the clutter automatically.
Reduces white noise then improves the on-screen
S/N ratio by processing the weighted moving aver-
age filter for the received echoes in the range direc-
tion. Use this function with caution. Weak target
echoes may disappear from the screen or the range
resolution may worsen.
