ABSTRACT:
An electronic proximity fuse of the FM radar type having a detonating circuit with two inputs. One input is derived from a signal representing the amount by which the frequency of the received signal differs from the frequency of the transmitted signal at the instant of reception averaged over the frequency-modulation period. The second input is derived from a signal proportional to the amount of the frequency fluctuations of the frequency deviation about the averaged amount.
