In this paper, the frequency spectrum, power specrum and time domain expressions of FM noise jamming, which features wideband and high-efficiency, are presented. In addition the effective noise power of FM noise jamming received by PD fuze antenna and time domain expressions of jamming noise signal output by MMW Random Binary-Phase-Code PD fuze frequency mixer and decoder are discussed. The frequency spectrum and time domain signal are generated in computer and therein the effective noise power of FM noise jamming received by PD fuze antenna are processed and compared with receiver sensitivity to check the fuze power of suppressing FM noise jamming.
