11.3.5 Suppressing radar interference
Mutual radar interference may occur in the vicinity of another shipborne radar operating in the
same frequency band (9 GHz). It is seen on the screen as a number of bright spikes either in
irregular patterns or in the form of usually curved spoke-like dotted lines extending from the
center to the edge of the picture. This type of interference can be reduced by activating the
interference rejector circuit.
