在深入分析目标极化回波的基础上，针对互易性目标，提出了一种基于交叉极化分量相位对齐的散射矩阵校准方法。
A method of measuring and calibration based on aligning the phase of the cross-polarization of the scattering matrix is proposed.
但是，由于不同极化状态回波信号之间的相关性，极化数据不可避免地产生数据冗余，反而增大了岩性分类的误差。
But meanwhile, the data fusion coming from the coherence of different polarizations in the polarimetric data produces more error for lithological classification.
雷达回波信号中，除幅度、相位和多普勒频移外，还存在第四特征——极化信息。
Besides amplitude, phase and Doppler frequency, polarimetric information is the fourth characteristic in the radar echo.
