ABSTRACT:
A fuze for accurately sensing the distance to a target irrespective of the resence of a medium intermediate of the fuze and the target. The fuze includes a source of radiation which is transmitted to the target and a detector which detects the backscatter from the target and intervening media. The detector output is amplified in an amplifier connected thereto and filtered in a filter connected to the amplifier to provide an output signal which is threshold detected in a threshold device connected to the amplifier. The threshold detected signal is applied to a firing circuit to provide a signal responsive to a predetermined distance above the target.
