Phased array antenna calibration method, device, computer equipment and storage medium

Abstract

The invention relates to a phased array antenna calibration method, a device, computer equipment and a storage medium. The phased array antenna calibration method comprises the steps that: when a calibration horn antenna is located at a first calibration position, symmetric plane phase difference zero correction is conducted on all receiving channels and all transmitting channels of equipment to be detected, wherein the first calibration position is a position where a pitch angle of a transceiving surface of the calibration horn antenna and a pitch angle of the transceiving surface of the equipment to be detected are 0 degree; and when the calibration horn antenna is located at a second correction position, azimuth pitch phase difference zeroing correction is carried out on each receivingchannel and each transmitting channel of the equipment to be detected, wherein the second correction position is a position where the pitch angle of the transceiving surface of the calibration horn antenna and the pitch angle of the transceiving surface of the equipment to be detected are alpha, and alpha is greater than or equal to 0 degree and less than or equal to 90 degrees. By adopting the phased array antenna calibration method, multi-channel transceiving one-time correction can be realized, and the correction accuracy is not reduced.

Description

technical field [0001] The present application relates to the field of phased array calibration technology, in particular to a phased array antenna calibration method, device, computer equipment and storage medium. Background technique [0002] With the development of antenna technology, phased array antenna technology has emerged. Phased array antenna refers to an antenna that changes the shape of the pattern by controlling the feeding phase of the radiating elements in the array antenna. The calibration of the phased array antenna directly affects whether the phased array antenna can work normally, so the calibration of the phased array antenna is particularly important. [0003] In the traditional technology, when calibrating and testing the phased array antenna, the power meter is generally used to make auxiliary statistics on the receiving channel of the signal, and to perform auxiliary correction error on the receiving channel of the signal, so as to realize the calibr...
