首发时间:2013-10-04
Abstract:In this paper, a distributed SAR moving targets 3D imaging method based on compressed sensing algorithm is presented. The moving target 3D signal sparse signal model is derived, and then the moving targets 3D signal reconstruction method based basis pursuit is established. In the case of low amount of data, we realize the distributed SAR moving target high-resolution 3D imaging. Finally, the simulation results verify the correctness and validity of the proposed algorithm

基于压缩感知的非均匀空间构型分布式SAR动目标三维成像信号重构研究
摘要:本文主要研究了一种基于压缩感知的分布式SAR动目标三维成像方法。推导了动目标三维稀疏信号模型,并建立了动目标三维信号重构新方法并与传统信号重构方法进行了比较。这种方法解决了成像欠定方程组求解的技术难题,在较低数据量情况下,实现了分布式SAR动目标的三维高分辨成像。最后通过仿真实验验证了本文算法的正确性及有效性。
