1.16 Interference Rejector
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. “IR” and the rejection level indicator
“L,” “M” or “H” appear at the top right corner
when the interference rejector circuit is on.
Appearance of interference
Turn off the interference rejector when no
interference exists, to avoid missing small
targets.
