Abstract

The receiver comprises a plane photoelectric detector with a number of detector elements connected with receiving circuits which deliver elevation and lateral deviation coordinates of target image w.r.t. two rectangular coordinate axes passing through the tracking plane centre. An optical pulse generator (1) generates the radiation. An optical receiver (3, 4) has a filter in the emission spectrum band, and detectors (5-8) are placed symmetrically on both sides of the coordinate axes (X, Y). The detector includes four identical quadrant elements. An amplifier with a variable gain (23) receives input signals from each quadrant, three of the signals passing through delay elements (20, 21, 22).
