| 摘 要： | 本文在导出ＳＡＲ图像成像方程式的基础上提出了ＳＡＲ立体定位的原理和方法，并从理论上分析了影响ＳＡＲ立体定位的主要因素。实验结果表明，本文提出的立体定位方法是正确的，影响定位精度的主要因素是交会角的大小与距离向量测误差，其与理论分析模型一致。

| Abstract: | A Stereopair positioning algorithm based on "Equivalent Line Central Projection" is presented for SAR Images in this paper. Then the accuracy potential is analyzed. The theoritical error models and the experimental results show that the main factors affecting the accuracy are radargrammetric configurations and the measured errors in range direction. |
