The paper proposed a new scheme for parallel implementation of compressive sensing based SAR imaging on GPU with Iterative Shrinkage/Thresholding algorithm. To get a faster recovery speed, we modified the existed IST algorithm structure, and realized the fast implementation on GPU. The experiment result shows that parallel computing capabilities of GPU have a significant speedup in comparison with computing capability of CPU.
