中文摘要：
利用简缩极化SAR模式下得到的散射向量对极化方向角的估计进行了推导。通过对圆极化形式的分析，将其用于简缩极化模式下的散射向量，利用简缩极化散射数据得到极化方向角的估计值。同时采用实测数据进行实验验证该方法，探讨了简缩极化模式下极化方向角估计的可行性和应用价值。
英文摘要：
In recent years, the research of compact polarimetric （CP） modes has caught attention . By using the full polarimetric （FP） mode, the existence of orientation angle （OA） induced by terrain slope will lead to the difficulty in post-processing, such as terrain targets classification and identification. In the paper, the OA estimation is derived and analyzed by using the scattering vectors of CP SAR modes. Recurring to the circular polarimetry, the OA can be evaluated from the CP SAR data. And the experimental results based on measured data sets have been shown to improve the estimation methods, while analyzing the practicability of the estimation under CP modes and its value in engineering application.
