Parallel Implementation of SAR Imaging on DAWNING3000

摘要

With the development of SAR processing techniques, high image precision and high real time rate have becoming an important index, especially on military filed. This paper presents a medium grained 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 DAWNING3000 shows this parallel processing algorithm can get good result on real time rate and processing efficiency.
