| 摘 要： | 星载合成孔径雷达（SAR）是一种工作在微波波段的主动式遥感器,它综合运用合成孔径技术、脉冲压缩技术和数据处理技术,采用较短的天线就能够获得方位和距离两个方向的高分辨率雷达图像。研制星载SAR系统的目的是获得具有一定测绘带宽和一定分辨率的地面目标图像,传统SAR模式不能同时满足高分辨率及较宽测绘带的要求。本文主要研究了多...

| Abstract: | Spaceborne Synthetic Aperture Radar(SAR) is an active sensor dedicated to remote sensing that works at the microwave portion of the electromagnetic spectrum.Among all the performance parameters of spaceborne SAR,resolution and swath width are the most important characteristics.In this dissertation,special problems in spaceborne DPC-MAB SAR imaging are analyzed,and this paper put forward one reconstruction algorithm by interpolation to the periodically nonuniformly sampled echo signals in azimuth. |
