Abstract

PURPOSE:To correct the direction of an antenna beam under the state where the antenna is used, by correcting an energizing phase on a basis of the energizing phase of the antenna element and information for a desired direction of the antenna beam. CONSTITUTION:A laser beam is irradiated to light modulators 71-7n from a laser beam source 9 by a light deflector 11, and incident lights are modulated by energizing signals of antenna elements 61-6n. These modulated lights are returned to the light deflector 11 and are demodulated successively by a light demodulator 12, and the phase difference between demodulated lights and a reference phase signal from a distributor 2 is detected. Energizing phases of antenna elements 61-6n are obtained on a basis of this detection value and the output of a range finder 14 which detects the position of antenna elements. Further, a desired direction of the antenna beam is detected by a direction sensor 15, and the phase shift quantity of a phase shifter 4 is corrected on a basis of energizing phases of antennas 61-6n and the desired direction by an operation control device 16.
