Abstract : An FM doppler fuze system comprising means for combining a periodic wave with white noise, white noise being a random mixture of frequencies possessing a constant power spectral density, means for modulating a carrier frequency with said periodic wave plus noise and transmitting a signal in the direction of a target, means for mixing a portion of said transmitted signal and a return echo signal from a target, and means for passing the band of expected doppler frequencies from the output of said mixer to provide an output operable to actuate the detonation circuit of a fuze.
