Deformation analysis of SAR image geometry correction based on diving model

This paper concentrates on the error analysis of SAR image geometry correction based on the diving model. In the geometry correction, a number of key parameters measured by the inertial navigation system must have some inevitable errors, and that will introduce some errors to the image pixels´ coordinates. The errors between the image pixels, especially the error caused by height error will cause the image deformation, and these errors are analyzed in this paper. Finally, the correctness of the deformation error analysis is verified by simulation results.
