摘　　要：在原始Chirp Scaling(CS)算法的基础上,详细推导了改进CS算法,并利用改进CS算法对超宽带合成孔径雷达(UWB SAR)进行成像,将成像结果与原始算法的成像结果比较后,其结果证明该算法突破了原始算法的局限性,能对大处理角的超宽带合成孔径雷达成像。In this paper, an extended Chirp Scaling algorithm is deduced in detail base on original CS algorithm, and the imaging results are received with applying it to UWB SAR. Comparing with the results of original CS algorithm, as a result we can get it that the extended CS algorithm break through the limit of original CS algorithm and is suitable for UWB SAR with big azimuth angle.
