Abstract

A proximity fuze of adjustable maximum range, configured to detect target pulses reflected only from a target within the lethality range of the associated warhead. My invention comprises a wideband switchable video amplifier connected to receive target pulses detected by a detector, and serving to supply therefrom an amplified version of the pulses to a pulse counter. The wideband switchable video amplifier is connected to receive signals from a gate generator, which signals do not interfere with the passage through the video amplifier of pulses representative of a target that will fall within the lethality range of the associated warhead. However, the gate generator provides blanking signals to the video amplifier that serve to prevent pulses reflected from a target outside such lethality range from reaching thepulse counter, and therefore preventing inappropriate detonation of the warhead. Quite advantageously, my novel fuze concept is usable with electro-optical devices or with radar.
