BEAM DIRECTION ADJUSTMENT METHOD AND APPARATUS, AND ANTENNA SYSTEM

WIPO Patent Application WO/2021/098493

A1

Disclosed by the present application is a beam direction adjustment method, applied to an antenna system comprising a microwave antenna and a radome, said radome comprising a liquid crystal array consisting of M×N liquid crystal cells, said method comprising: obtaining the azimuth angle and/or pitch angle of the microwave antenna; according to the azimuth angle and/or pitch angle, determining a target scan angle of the microwave antenna; determining a first bias voltage value of the liquid crystal array according to the target scan angle; setting the voltage of the liquid crystal array as a first bias voltage value. Also provided by the embodiments of the present application is a corresponding device. In the technical solution of the present application, if the microwave antenna is detected to have deviated to a certain angle, the transmission phase of the liquid crystal cell can be changed by means of adjusting the liquid crystal bias voltage of the liquid crystal array in the radome, thus achieving a corresponding phase distribution such that the beam of the microwave antenna scans said angle, achieving automatic tracking and alignment.
