3D positioning assessment for stereo configuration conditions of airborne SAR images in mountainous area

This paper analyzed the parameters, which influenced 3D positioning according practical imaging conditions of high-resolution airborne SAR system. And, by constructing a common airborne SAR stereo configuration model, it analyzed the relations of various stereo configuration factors, including stereo intersection angle, baseline length, image area overlapping ratio, trajectory intersection angle, terrain height and so on. And then, through the corresponding parameter values under the stereo configuration conditions to evaluate the final influence on the three dimensions positioning of ground objects. The test data are come from IECAS, 1m-resolution, covered the mountainous area of ZiGong (SiChuan Province), Western of China. The corresponding results of this experiment about assessment analysis were presented, which will be to be helpful to guide to design flight courses or airborne SAR system design for future applications.
