Abstract 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.
