Device for optical control of a beam-scanning antenna |
摘要 |
Beam-scanning of an antenna by means of microwave phase shifts is achieved by N electrooptical modulators which receive two collinear beams having different frequencies. The modulators define optical paths having different wavelengths. N photodetectors make it possible to receive the beams reflected by the modulators and to control antenna elements during a 2 pi phase excursion.
