Title:
【発明の名称】電子走査アンテナの光学的制御装置
Document Type and Number:
Japanese Patent JP2754488
Kind Code:
B2
Abstract:
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.
