| 摘 要： | 星载SAR的大距离徙动对成像算法构成了严重挑战,本文基于FIR滤波,结合RD算法加以优化,提出了一种适应大距离徙动的并行快视成像的实现方法。运用并行处理,在8CPU内存共享的SGI服务器上实现了分辨率降低8倍的快视成像。仿真实验表明,本文方法基本可以达到准实时成像的要求。

| Abstract: | Large range migration is a severe challenge to imaging algorithm of spaceborne SAR. Based on design of FIR filter and RD algorithm, a realization for quick look imaing of large range migration is proposed. It realized quick look imaging of decrease resolution 8 times with parallel process on memory shared 8 CPU SGI server. According to simulation experiment, this quick look imaging with prarllel process can reach the requirement of real time or near real time. |
