Affection of polarimetric orientation angle for yamaguchi model decomposition
极化方位角对Yamaguchi参数分解的影响

Based on the polarimetric orientation angle estimation,we discuss the decomposition error caused by the azimuth slope. We analyze the azimuth slope effects on the Yamaguchi model,and use the polarimetric SAR azimuth estimation to reduce the terrain effect. Finally,we apply this approach to a full polarimetric AIRSAR image of San Francisco from 1992. The experiments show that the polarimetric orientation angle composition could improve the precision of the Yamaguchi model.
