A device is provided for use in a proximity-type fuze which includes a rectangular wave generator, the output of which is differentiated to provide pulses for exciting an antenna, which pulses are at the same time used to bias one or more diodes to conduction for passing signals reflected by a target to a sawtooth wave generator whose sawtooth output has its magnitude and period controlled by the differentiated pulses, the sawtooth output having its magnitude controlled by the signals reflected from the target and particularly the time relationship of the latter relative to the period of the rectangular wave.
