平飞斜视模式下双站SAR成像算法比较

Comparison of Bistatic SAR Imaging Algorithms With Parallel Flight Squint Mode

为了改善机载双站SAR平飞斜视模式下的图像聚焦精度,对SRCRD算法和ECS算法进行了研究,分别给出了实现流程,并进行了计算机仿真.结果表明在平飞斜视模式下ECS算法性能明显优于SRCRD算法.

For the purpose of improving the image focusing accuracy in parallel flight squint mode of airborne bistatic synthetic aperture radar （SAR）, both SRCRD algorithm and ECS algorithm were studied. Simulations were carded out after presenting flowcharts of the two algorithms. The upshots of simulations make it clear that the performance of ECS algorithm is apparently better than that of SRCRD algorithm in parallel flight squint mode.
