The depth of the detected target is usually satisfied with the far-field condition, and can be approximately regarded as plane wave propagation. The polarization of the plane wave refers to the time-dependent change of the field vector direction at a given point in space. Generally, the polarization can be classified into linear polarization, circular polarization, and elliptical polarization. Wave polarization is an important characteristic of electromagnetic waves, and waves with different polarization modes have different engineering applications. When the underground medium has anisotropy, plane waves are incident in a linear polarization mode, and reflection echoes of the plane waves can be converted into an elliptical polarization mode. Therefore, information on the physical properties of the underground medium can be obtained by studying the change in the polarization mode of the radar wave.
