PALSAR L波段SAR受法拉第旋转的影响。本文首先简要介绍了PALSAR系统，并将Freeman方法应用于PALSAR定标。除非在国外测量通道不平衡，否则必须为每个待校准的场景部署参考点目标。为了实际应用，本文研究了对称目标在极化PALSAR数据校正和验证中的应用
PALSAR L-band SAR is affected by Faraday rotation. In this study, PALSAR system is briefly described, and Freeman's method is considered for the calibration of PALSAR. Unless channel imbalances are measured abroad, a reference point target has to be deployed for each scene to be calibrated. For practical reasons, the use of symmetric targets is investigated for calibration and validation of polarimetric PALSAR data
