摘要
随着SAR成像技术的不断发展,对SAR图像的成像精度和实时率的要求也愈来愈高,尤其是军事领域,高实时率是SAR成像系统的一个关键指标。该文提出了一种基于CS成像算法的中粒度SAR并行成像算法,该算法中每一个处理步骤均能并行完成,是一种任务级的并行,适合于具有较高通信性能的并行处理系统。在曙光3000上的实验证明,该算法具有较高的实时率和并行效率。
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 DAWNING3000 show this parallel processing algorithm can get good results on real time rate and processing efficiency.
