Ground state calibration method for broadband wide-scanning active phased-array antenna

The invention discloses a broadband wide-scanning active phased-array antenna ground state calibration method, which is characterized in that ground state calibration of a phased-array antenna is a very important link in a phased-array antenna development process, and the performance of the phased-array antenna is directly influenced by the antenna calibration. The method comprises the following steps: acquiring ground state data of each TR component of the antenna; performing all-state data acquisition on each delay component of the antenna; data processing and algorithm implementation; and a phased-array antenna design with relatively good ground state calibration is obtained. The invention discloses a ground state calibration method based on a delay error, and the method enables the amplitude-phase compensation of a TR assembly to be matched with the delay compensation of a delay amplification assembly, thereby improving the broadband performance of a phased-array antenna. 本发明公开了一种宽带宽扫有源相控阵天线基态校准方法，相控阵天线的基
