Proximity responsive apparatus capable of being used, for example, as a fuzing device for a bomb includes means for generating and emitting pulses of energy which conform to a predetermined time varying waveform. Reflected energy is sampled at two or more spaced instants in time, and the sampling instants are chosen in accordance with the required range of operation of the apparatus and also the shape of said waveform. The samples are compared and the result of the comparison is a signal used to control the fuzing of the bomb.
