Circular array antenna real-time calibration method

The invention discloses a circular array antenna real-time calibration method, which comprises the steps of comparing each path of signals to be calibrated in a circular array antenna by using a set calibration reference signal, and determining amplitude-phase data corresponding to each path of signals; performing iterative processing on the amplitude-phase data corresponding to each path of signals for multiple times to obtain radio frequency channel calibration data of the circular array antenna; and performing phase calibration on the radio frequency channel calibration data of the circulararray antenna to realize real-time calibration of the circular array antenna. 本发明公开了一种圆阵天线实时校准方法，包括：利用设置的校准参考信号，对圆阵天线中每路需校准的信号进行比较，确定每路信号相应的幅相数据；通过对所述每路信号相应的幅相数据进行多次迭代处理，得到所述圆阵天线的射频通道校准数据；通过对所述圆阵天线的射频通道校准数据进行相位校准，实现所述圆阵天线的实时校准。
