FIELD: optics.
SUBSTANCE: invention relates to recognition of information patterns and can be used in laser location systems for recognition of signals reflected from optoelectronic equipment (OEE). Method of recognition of location optical signals, based on radiation of laser location signal, reception of reflected laser signal, differs by dividing the received reflected laser signal into two identical streams, measuring the spatial coherence radius of the first laser stream and the radius of the formed image of the second laser flux, the values of which are compared to each other, and by their equality optical-electronic facility is recognized as object of reflection of laser location signal.
EFFECT: technical result consists in improvement of efficiency of recognition of signals reflected from OEE.
