<p>of the disclosure. A proximity fuze (74) of adjustable maximum range, configured to detect target pulses reflected only from a target within the lethality range of an associated warhead (76). The invention comprises a wideband switchable video amplifier (30) connected to receive target pulses detected by a detector (28), and serving to supply therefrom an amplified version of the pulses to a pulse counter (54). The wideband switchable video amplifier (30) is connected to receive signals from a gate generator (40), which signals do not interfere with the passage through the video amplifier (30) of pulses representative or a target that will fall within the lethality range of the associated warhead (76). However, the gate generator (40) provides blanking signals to the video amplifier (30) that serve to prevent pulses reflected from a target outside such lethality range from reaching the pulse counter (54), and therefore preventing inappropriate detonation of the warhead (76). Quite advantageously, the novel fuze concept is usable with electro-optical devices or with radar. Fig. 1.</p> |
