研究和发展了极化合成孔径雷达数据的地形校正方法。正射校正和振幅校正利用斯托克斯矩阵数据。在幅度归一化之前减去热噪声的Stokes矩阵。方位角斜率校正算法的应用导致与输入数据相比取向角的分布稍微更窄。
Methods for terrain correction of polarimetric SAR data were studied and developed. Ortho-rectification resampling and amplitude correction utilized Stokes matrix data. The Stokes matrix of thermal noise was subtracted before amplitude normalization. Application of an azimuth-slope correction algorithm resulted in slightly narrower distribution of orientation angles compared to input data.
