多姿态角下的目标散射中心关联与成像方法研究

雷达成像是获取目标结构信息的重要手段,本文根据目标散射中心在雷达视线上的投影关系,分析了多姿态观测下的目标散射中心三维成像原理,基于真假散射中心的特性差异,引入复合弹性系数模型实现多姿态角散射中心关联和成像。实验采用仿真数据和暗室测量数据进行成像实验,结果表明算法具有成像稳定、结构清晰等优点。

Scattering Centers Association and Imaging Based on Multi-aspect Measurements

Radar imaging is an important way to obtain the structural information of target.Based on the geometrical projection of scattering center on the line of radar sight,the principle of reconstructing scattering centers'3-D distribution based on multi-aspect measurement is provided in the paper.After analyzing the characteristic differences between the true and false scattering centers,the multiple elastic modules(MEM)is introduced to realize scattering centers association and radar target imaging.The experiments are de- veloped with simulated and measured data,and experimental result shows the robustness and imaging legibility of performed algorithm.
