距离迁移成像算法在超宽带SAR成像中的应用

Application of RMA to UWB SAR Imaging

超宽带SAR是一种新体制雷达 ,在成像处理方面有特殊要求。本文详细介绍了距离迁移算法 ,对其每一个处理流程进行了详尽的分析 ,并进行了计算机仿真 。

Low-frequency, ultra-wideband/widebeam (UWB/WB) SAR imaging faces inherent challenge which is not presented in conventional SAR system operating at higher frequencies. Range migration algorithm (RMA) suitable for UWB SAR imaging is discussed in detail with theoretical analyzing and computer emulation. RMAs validity is confirmed by experiment result.
