ABSTRACT:
A proximity detector device comprises a lens placed at the front of the missile, two circular infrared detectors of different radii centered on the optical axis of the lens and disposed in its focal plane. An electronic circuit is connected to the detectors for delivering a proximity signal when the time slot separating two pulses emitted by the two detectors is less than a predetermined threshold. The explosion of the missile is controlled by the proximity pulse.
