3.4.1 Interference Rejection (IR)
Interference by other radars is rejected.
Procedures 1 Left-click the IR combobox located at the lower left of the radar
display.
2 Select the interference rejection modes to set from the list.
The interference rejection modes are switched.
Rejection levels of the interference rejecter
IR Off : Interference rejecter off
IR Low : Interference rejection level - low
IR Medium : Interference rejection level - moderate
IR High : Interference rejection level - high
When a high interference rejection level is selected, the radar’s ability of detecting small
targets such as buoys and small boats lowers.
In general, IR Low should be selected.
z When viewing a radar beacon or SART signal, select
IR OFF (Interference Rejector OFF) because IR
processing suppresses the video.
