Abstract: Marked degree of drift can occur on the quiescent output of capacitance fuze detectors with variations in temperature. Beginning with the stabilization of the oscillator's amplitude and expansion of the operational region of the detection stage, a few methods for. the suppression of drift in the quiescent output are proposed. Circuits for their realization are given, and the principles of selection of the major parameters are discussed. A kind of new detector is provided. It possesses not only the high detection efficiency of an active detector, but also a wide operation region of a passive detector.
