ABSTRACT:
1. An electronic ordnance fuze responsive only to a signal of increasing litude applied for at least a predetermined minimum time, said fuze comprising: means for radiating radiofrequency energy, receiving a portion of said radiofrequency energy after reflection from a target, and mixing the radiated and reflected energy to obtain a Doppler-frequency alternating current signal of increasing amplitude as the fuze approaches the target; means for amplifying said alternating current signal; rectifier and filter means for obtaining from the amplified alternating current signal a first unipotential signal proportional to its envelope; differentiator means connected to said rectifier and filter means for obtaining a second unipotential signal which is proportional to the rate of change of said first unipotential signal; limiter means connected to said differentiator means for limiting the amplitude of the output of said second unipotential signal; and an integrator and trigger circuit to which said second unipotential signal is fed, said circuit producing a pulse which initiates detonation when said second unipotential signal has at least a predetermined minimum amplitude for at least a predetermined minimum time.
