[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation.
[0015] figure 1 It is a basic flowchart of the adaptive polarization measurement principle of the technical solution of the present invention. As shown in the figure, the present invention includes four processing steps. The orthogonal dual-mode horn dual-polarization antenna receives the radar signal, performs amplification, filtering, frequency mixing and intermediate frequency processing through two channels, and then feeds polarization parameters and differential self- Adapt to the measurement module, and finally measure the polarization parameters of the radar signal by observing whether the adaptive tracking condition of zero value or minimum value is satisfied. The following are the detailed steps of the technical solution of the present invention.
[0016] In the first step, the dual-polarized antenna receives the radar electromagn...
