Abstract:
An antenna array calibration method and apparatus are provided. The method includes: when first target antennas in an antenna array transmit signals, and second target antennas in the antenna array receive the signals, calculating calibration compensation values of transmit channels in the first target antennas and calibration compensation values of receive channels in the second target antennas; and when the second target antennas transmit signals, and the first target antennas receive the signals, calculating calibration compensation values of transmit channels in the second target antennas and calibration compensation values of receive channels in the first target antennas.
