| 摘 要： | 首先推广了现有极化定标模型。在此基础上，评估了极化通道幅相不平衡、天线串扰、法拉第旋转、指向误差角、干扰和系统环境噪声对点目标全极化散射测量的影响，并考虑科学研究和应用需求对上述参数的约束条件，从而得到对极化合成孔径雷达系统设计和极化定标有参考价值的结论。

| Abstract: | This paper generalizes the normal polarimetric calibration model, and evaluates effects on full polarization scattering measurement of a point target from amplitude and phase inbalance of polar channels, crosstalk of antenna, Faraday rotation, target orientation error, interference and noise from system and environment. And some valuable conclusions for design of polarimetric synthetic aperture radar and polarimetric calibration are achieved from constraints of scientific research and application requirements. |

| Keywords: | polarimetric synthetic aperture radar point target scattering measurement polarimetric calibration |
