Abstract : A high altitude pulse doppler ordnance fuze which includes a plate pulsed oscillator having an integrated loop antenna. A modulator coupled to the plate pulses the oscillator to provide main and secondary pulses. The main pulse produced in the oscillator is radiated to a target and the echo therefrom interacts with the secondary pulse produced in the oscillator to provide grid current variation indicative of doppler signal. Gate circuitry, including a differentiating circuit, monostable multivibrators, and a reset network, is responsive to the modulator output to gate a detector to detect the grid current variation and, therefore, obtain doppler information upon interaction of the echo and secondary pulse signals.
