Abstract

An electro-optical IFF system easily integrable into existing laser systems uses a laser to illuminate a potential target platform. The potential target, if friendly, has apparatus for returning to the illuminating platform a return beam which has the same signature but is delayed with respect to the illuminating beam by a predetermined time interval. If the illuminating platform sees a return beam with the same signature in the proper time frame, an indication is generated that the target is friendly. A friendly target platform contains apparatus for comparing the signature of the illuminating beam to a stored reference signature, and for providing a friendly-illumination indication and activating the return beam only if the signatures match.
