摘要
With the resolution of SAR developing continually, it is found that in the process of image processing, using equivalent squint range model would bring large phase error. So using traditional CS algorithm for processing will encounter difficulties. In order to solve this problem because of unsuitable slant range model, this paper introduces the fourth-order slant range model to replace the original model, and conducts a study on CS algorithm based on the fourth-order slant range model. This paper introduces the theoretical formulation and simulation results of the new algorithm. This algorithm can perform well for both low-resolution space-borne SAR and high-resolution space-borne SAR.
