Long-distance waveform radar polarization calibration method based on common strong point target

The invention provides a long-distance waveform radar polarization calibration method based on a common strong point target. The long-distance waveform radar polarization calibration method can be used for performing polarization calibration on a long-distance waveform of a fully-polarized radar. According to the method, firstly, an experimental scheme is designed by combining the characteristics of a multi-waveform radar, and a passive polarization calibration method for a common strong point target based on a different-waveform common measurement area is provided. Compared with an existing polarization calibration algorithm, the method aims at the problem that a radar long-distance waveform external field experiment is difficult to carry out, and calibration of the long-distance waveform is achieved through the short-distance waveform easy to calibrate. 本发明提供了一种基于公共强点目标的远距波形雷达极化校准方法，可用于对全极化雷达的远距波形进行极化校准。本发明首先结合多波形雷达的特点设计实验方案，并提出了一种基于不同波形公共测量区域的公共强点目标的无源极化校准方法。相对于已有的极化校准算法，本方法针对雷达远距波形外场实验难以开展的问题，通过易校准的近距波形实现
