<p>A missile is provided with a proximity fuze arranged to transmit a signal and to receive echoes for activating an explosive charge when an object is within range. A signal processing device located between the receiver of the fuze and the charge is responsive to signals from the receiver and to a blocking signal of predetermined duration, and operates to transmit a control signal for initiating explosion of the charge only if the blocking signal has terminated and a predetermined time interval has elapsed, preceding occurrence of a receiver output signal, during which interval no output signal was produced by the receiver.</p> |
