| 摘 要： | 滑动SAR是一种新颖的SAR成像模式,它通过控制辐照区在地面移动的速度来增加方位向相干累积的时间,从而提高SAR方位向的分辨率.该文从成像机理、回波方程、分辨率、天线扫描以及测绘带宽等方面对滑动聚束SAR进行了详细分析,并且给出了滑动聚束SAR的波数域成像算法.通过对条带SAR,聚束SAR,滑动聚束SAR的比较,可以看出条带SAR和聚束SAR都是滑动聚束SAR的一种特例.

| Abstract: | Sliding spotlight SAR is a novel mode of SAR imaging, which can improve azimuth resolution by controlling the speed of antenna footprint to increase coherent accumulation time. This paper analyzes the sliding-spotlight mode at the aspects of imaging principle, echo model, resolution, antenna operational mode, swath width, etc. And it presents the “wavenumber domain” algorithm of sliding-spotlight SAR. Compared with stripmap and spotlight SAR imaging, both stripmap and spotlight are special forms of sliding-spotlight mode. |
