ABSTRACT:
An opto-electronic antenna system includes a plurality of transmitting/receiving antennas disposed over a prescribed geometrical surface such as a sphere. To the antennas are optically coupled transmitter/receiver units such as photo-detectors or laser transmitters. The antenna units are scanned electronically according to their position on the geometrical surface by supplying to the individual units, signals differing in phase in accordance with the position of the antenna with which the units are associated both in the vertical and horizontal directions. An evaluation circuit is associated with each unit for determining the azimuth and elevation directions of received radiation. The antennas are constructed of a multitude of lenses having a hexagonal shape.
