Jamming of radar guided missile receivers are extremely difficult as the frequency lock and the servo lock requires no deviations in the repeater waveform of the jammer and its frequency. Broadband repeat jamming of such missile radar receiver is illustrated in this paper for effective deception in the presence of FM CW (Continuous Wave) interference signal. The modulation index of the FM jammer required for breaking the frequency lock of the monopulse receiver is determined and its variation with radar echo signal amplitude is presented.
