Base station antenna common aperture REV amplitude-phase correction method

The invention provides a base station antenna common aperture REV amplitude-phase correction method, which is characterized in that a correction reflecting plate is arranged at an antenna aperture toimprove an antenna coupling relationship, correct reflecting plate wave-transmitting work during normal work, correct reflecting plate semi-wave-transmitting work during correction, change a couplingrelationship between a correction antenna and a base station antenna radiation unit, and increase the coverage area of the correction antenna; and the correction antenna and the base station antenna are integrated in the same aperture, the use requirement of online amplitude and phase correction of the base station antenna is met, and meanwhile, a correction REV method for eliminating the multi-value problem of the REV method is adopted in the correction algorithm to realize online amplitude and phase correction of the base station antenna. The array scale of the base station antenna is partitioned, the subarrays are n
