Noise Rejection - Simrad R2009 User Manual

Noise rejection

The Noise Rejection control sets the amount of noise filtering applied by the radar. Target
sensitivity is increased at longer ranges when this control is set to Low or High, but does
cause some loss of target discrimination.
Target boost
The target boost control increases pulse length or reduces radar bandwidth to make targets
appear larger in range and increase radar sensitivity.
Target expansion
Target expansion increases the length of targets in range, making them easier to see.
Target separation
The Target separation control allows you to control the target discrimination of the radar
(separation between objects is more prominent).
Fast scan
Sets the speed of the radar antenna rotation (from 20 RPM in standard mode to 36 RPM in
Fast scan mode). This option gives faster target updates.
