摘　　要：与双站条带SAR相比,双站聚束SAR只要有足够的聚束时间,理论上就可以达到理想的方位分辨率,不受收、发天线波束宽度和天线尺寸大小的影响.文中主要研究双站聚束SAR方位分辨特性、波束压缩比等,并给出了相关数学解和仿真结果.Compared to bistatic strip synthetic aperture radar （SAR）, given enough observation time, bistatic spotlight SAR can achieve ideal azimuth resolution, which isn＇t affected by both beam width and antenna size of transmitter and receiver. The performance of azimuth resolution and beam compression ratio （BCR） etc. of the bistatic spotlight SAR are studied in detail in this paper. Analytical solutions are obtained, the results of computer simulation are presented.
