A circuit for compensating for frequency modulation on a radar signal is disclosed. The disclosed circuit includes an adaptive narrow band filter in the feedback path of a phase-locked detector, such filter having a bandwidth which is narrower than the frequency range of the signal being compensated, and means for detecting the amplitude of such signal. The invention herein described was made in the course of, or under a contract or subcontract thereunder, with the Department of Defense.
What is claimed is: 1. In a semiactive missile guidance system wherein a frequency modulated continuous wave signal illuminates a guided missile to provide a reference signal at such missile and also illuminates a target to provide an echo signal directed to such missile, the reference signal and the echo signal being processed in the guided missile to derive guidance signals for such missile, an arrangement for compensating for the frequency modulation on the echo signal, such arrangement comprising: (a) first means for detecting the frequency modulati...
