Abstract With the development of SAR processing techniques, high image precision and high real time rate become an important index, especially on military field. This paper presents a medium granularity parallel processing algorithm for SAR imaging. In this parallel processing algorithm, every processing stage is done in parallel, and the degree of parallelism is task-level. It is fit for the parallel computer with good communication capacity. The experiments on DAWN1NG3000 show this parallel processing algorithm can get good results on real time rate and processing efficiency.
