一种适用于双天线InSAR系统的成像定位算法

内容简介：针对机载双天线InSAR系统实用化测图问题,提出一种将目标定位至数据获取几何的成像算法.该算法可以高效结合自配准处理.相对于将目标定位至零多普勒几何的传统算法,该算法优势在于减少了后续干涉处理过程三维定位的计算量,且成像算法效率与传统算法一致.该算法尤其适用于实用化机载双天线InSAR系统.

Abstract：In this paper,we presented an algorithm which can locate targets in data acquiring geometry and realize self-registration.The algorithm has an advantage over traditional algorithm which locates targets in zero doppler geometry.It can decrease computational burden of three-dimension geolocation and is as efficient as traditional algorithm.The algorithm is suitable for airborne dual-antenna InSAR system.
