  • Publication number: 20210126362
    Abstract: One example method includes transmitting a test signal through the transmit channel n, where the test signal is radiated by a service antenna element n corresponding to the transmit channel n and is received by a calibration antenna element in the phased array antenna. N coupling signals received by N calibration antenna elements coupled to the service antenna element n can then be obtained. Delay weighting can then be performed on the N coupling signals based on relative positions of the service antenna element n and each of the N calibration antenna elements to obtain N calibration signals. The N calibration signals can then be combined into the calibration signal corresponding to the transmit channel n. Calibration signals corresponding to all transmit channels in the phased array antenna can then be obtained. At least one of amplitudes or phases of the transmit channels can then be compensated for.
