摘要

The system of identification friend - enemy protected against intrusion and discriminating comprises: & br / - on the one hand, a station interrogator having a device for the designation "optronic" (1), of an interrogator (2) having an emitter emitting in the direction of an object which is designated by a pulsed laser beam coded and directional, and an optical detector which detects a laser beam coming from the designated object if it is coupled, & br / - and the other hand, on an object which is alloyed a transponder (3), in order to respond to actively an interrogation beam received by a pulsed laser beam coded and directed in the direction of the interrogator. & br / the optical detector of the interrogator comprises a plurality of elementary detectors independent to cover a field of reception thetac, but each having a field of the elementary thetad, in a multiple of the total field thetac, determining the capacity for discrimination of the system.
