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.

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, comprising a wideband switchable video amplifier connected to receive pulse inputs from a receiving means, a blanking control means, and a pulse counter, said video amplifier serving to supply an amplified version of said inputs to said pulse counter, said video amplifier also being connected to receive signals from said blanking control means, which signals from latter means do not interfere with the passage through said video amplifier of pulses representative of a target that will fall within the lethality range of the associated warhead, said video amplifier, however, receiving blanking signals from said blanking control means that serve to prevent pulses reflected from a target outside such lethality range from reaching said pulse counter, such that the warhead will not be detonated in latter instance.
