Signal processing function

Description

Section

Interference rejector

Suppress interference transmitted by other
radars. Interference received simultaneously from
many radars can be difficult to reduce.

1.25

Echo stretch

Enlarge target echoes, especially small echoes.
Suppress interference, sea clutter and rain clutter
before using echo stretch, to prevent the
enlargement of unwanted echoes.

1.26

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. Requires
position and speed data.

1.27

Noise rejector

Suppress white noise and increase the S/N ratio
to improve picture clarity.

1.28

Wiper

Suppress unwanted echoes that appear after the
sweep completes a scan (within one second).
