Calibration balancing method of phased array radar antenna transmitting and receiving channel

The invention discloses a calibration and balancing method for a receiving and transmitting channel of a phased array radar antenna, the calibration and balancing method is based on a phased array radar system, and the calibration and balancing method comprises the following steps: step 1, carrying out radar and horn erection; 2, calculating the phase difference of each receiving and transmitting channel relative to the reference channel by using a radar processor; and step 3, controlling the obtained plurality of phase differences to be phase shift values corresponding to the receiving and transmitting channels through a wave control module of the antenna unit, and verifying whether the phase differences of the receiving and transmitting channels and the reference channel after phase shift are balanced or not. According to the phased array radar correcting and balancing method, an additional testing system does not need to be purchased and built, correcting and balancing processing of all receiving/transmitt
