Abstract : The patent relates to a FM-CW fuze system and more particularly to a FM-CW fuze system with improved counter counter-measures and low altitude capabilities. This is accomplished by transmitting a noise-like dual modulated signal and comparing the return of this signal first with the undelayed transmitted signal and then with a second modulating source to insure that the signal which activates the firing circuit is in response to a target reflected signal rather than a spurious signal.
