摘　　要：SAR成像具有数据率高、数据量大、算法复杂、处理实时性较难保证的特点。目前随着大容量、高速并行计算机技术的迅速发展,成像雷达信号处理实时性问题的研究获得了很大的发展。介绍了一种基于ADSP-TS201实时信号处理系统的体系结构和SAR实时成像算法流程,最后通过试验论证了该方法的正确性。SAR imaging has the characteristics of high data rate,huge dada ,complex arithmetic and difficulty of real- time processing. At present,with the rapid development of technology of the bulky and high speed parallel computer,the study of the problem of SAR real - time signal processing makes a great progress. The system structure of the real - time signal proces- sor and the algorithm flow of SAR real -time imaging based on ADSP -TS201 are introduced in the paper. Finally,correctness of the method is proved experimentally.
