IECAS高分辨率机载合成孔径雷达几何精度试验

The Geometric Accuracy Test of the Airborne High Resolution SAR Developed by IECAS

本文以实际地形图数据，用经典的雷达摄影测量的方法，检验了中国科学院电子学研究所（IECAS）高分辨率机载合成孔径雷达的几何精度。结果表明：该雷达影像在单图像修测（对已有地图进行更新测量）条件下，平面位置精度优于±4m米；在立体图像量测的条件下，空间位置精度优于±20m。

In this paper, geometric accuracy of the airborne high resolution SAR developed by Institute of Electronics, Chinese Academy of Sciences （IECAS） is verified with real terrain map data by using classical radar photogrammetry.The experimental results show that horizontal positional accuracy of single imagery revision is better than ±4m and spatial positional accuracy of stereo images measurement is better than ±20m for the kind of radar imagery
