ABSTRACT:
A phase dependent radar guidance system, the receiver (18) of which separates returns into a channel (22) where returns are summed (S) and a further channel (24) where the returns are differenced (jD). The S and jD signals are combined (26) and formed into two further channels as S+jD and s-jD, both of which are passed through AGC controlled amplifiers (28, 30) into a phase angle detector (32) which provides the target (14) angle .beta. to boresight (20). A test signal is applied to the receiver (18) with jD=O, the output value of the phase angle detector (32) for various values of AGC attenuation are stored by a digital processor (34), and the processor (34) modifies measured target phase value with the stored values to correct for AGC amplifier-induced errors.
