摘要
随着合成孔径雷达 (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。针对目前较流行的SAR成像算法———CS(ChirpScal ing)提出了适合于群集 (cluster)结构的并行机的中粒度并行算法及粗粒度并行算法 。
With the development of SAR processing techniques, high image precision and high real time rate have become an important index, especially on military filed. This paper presents two parallel processing algorithms -- medium grained parallel algorithm and large grained parallel algorithm for SAR imaging based on CS algorithm. The algorithm structure and implementation are analyzed and discussed.
