Interference received simultaneously from multiple
radars may be difficult to reduce. See

Echo stretch Enlarges target echoes, especially small echoes.
Suppress interference, sea clutter and rain clutter be-
fore using echo stretch, to prevent enlargement of
unwanted echoes. See
section 1.23
Echo averaging 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. See
section 1.24
Automatic clutter elimination Discriminates clutter from the radar echo, then reduc-
es the clutter automatically. See
section 1.25
Noise rejector 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. See
