ABSTRACT:
An antijam device for use in radar and missile guidance systems which tra a doppler-shifted CW target echo by means of an automatic frequency control loop. Means are placed between the doppler filter and error detector portion of the automatic frequency loop to suppress the interference signal and generate an output signal which is essentially identical in frequency and amplitude to the target doppler signal which is tracked instead of the jamming signal.
