The spaceborne multi-angle SAR can perform multi-azimuth observation of the same scene with different obliquity orbits, and the target can be located by the multi-angle SAR images with the radargrammetry method. The positioning accuracy of target is affected by the system error and coregistration error. In this paper, the target location accuracy of multi-angle SAR is quantitatively analyzed. The stereo radargrammetry location accuracy of single orbit and multi-orbit images with different azimuth angles is analysed with simulated experimental data.
