ABSTRACT:
5. A pulse doppler proximity fuze comprising a self-pulsing oscillator for eveloping a series of radio frequency electromagnetic energy impulses, an antenna electrically connected to said oscillator for radiating said impulses into space and for intercepting reflected impulses thereby to effect a variation in the amplitude of said impulses, a pair of detectors electrically connected to the said oscillator circuit for developing an output signal in proportion to the energy of the said reflected signal during the peak amplitude of said impulse, a thyratron firing circuit said detectors having means for detecting spurious signals and target signals but utilizing only the target signals for firing the thyratron firing circuit; and an electroresponsive ignition device electrically coupled to the thyratron firing circuit, said device being ignitable upon actuation of the thyratron firing circuit by said target signal.
