本文提出了一种简单的极化角度补偿方法，使得利用四极SAR数据准确检测变形/倾斜建筑物成为可能。期望通过对进行常规方位角补偿(OAC)后的相干矩阵应用新的补偿，可以减少在建筑物倾斜侧壁和地平面之间产生的不希望看到的大的表面散射贡献。结合提出的补偿量和特征值/特征向量分析得到的角度α̅，β̅，可以构造简单有效的人造目标检测算法，适用于变形/倾斜建筑物的识别。
This paper proposes a simple polarimetric angle compensation to make accurate detection of deformed/inclined buildings possible by using quad-pol SAR data. It is expected that by applying the new compensation to the coherency matrix after doing conventional orientation angle compensation (OAC), undesired large surface scattering contribution generated between the inclined sidewall of the building and ground plane may be reduced. Cooperating with the pro-posed compensation and the angles α̅, β̅ obtained by the eigenvalue/eigenvector analysis, we can construct simple and efficient man-made objects detection (MOD) algorithm appropriate for identification of the deformed/inclined buildings.
