Abstract

For the spaceborne synthetic aperture radar (SAR), it is difficult to obtain high resolution and wide width at the same time. This paper proposes a novel imaging system based on tandem SAR satellites, where one obtains coarse resolution and wide swath by the scanning mode, and the other obtains the undersampled echo from the same swath. The high resolution is achieved by associating the tandem SARs' echo and using the minimum-energy-based algorithm. Finally, a high-resolution wide-swath SAR system is designed, and its imaging performance is verified by simulated data and real airborne SAR data.

摘要

对于星载合成孔径雷达（SAR）而言，要同时获得高分辨率和宽测绘带是很困难的。本文提出了一种基于串联SAR卫星的新型成像系统，其中一颗卫星通过扫描模式获得粗分辨率和宽测绘带，另一颗卫星获取来自同一测绘带的欠采样回波。通过关联串联SAR的回波并使用基于最小能量的算法来实现高分辨率。最后，设计了一种高分辨率宽测绘带SAR系统，并通过模拟数据和实际机载SAR数据验证了其成像性能。
