Abstract
A radar seeker employing a 4-element antenna and amplitude or phase comparison target location. The azimuth (C and D) and elevation (A and B) elements share two channels alternately by means of cycling switches (S1, S2). Sum (31) and difference (29) signals are derived from the two channels and then the difference channel is re-distributed (S4) to dedicated azimuth and elevation channels. The shared channels (G, H) are interchanged cyclically (S3) so that mismatches between them are cancelled out.
