一种稀疏重建的多基地雷达多目标定位算法
A Multi-static Radar Multi-target Localization Algorithm Based on Sparse Reconstruction
摘要
Abstract
It is required to know targets' number in the surveillance space because of low resolution after pulse compression in the projection localization method of multi-static radar multi-target based on range sum measurement. For this problem,a new sparse reconstruction based multi-static radar multi-target pro-jection localization algorithm is proposed. By exploiting the feature that the sparsity of targets is same in different receivers,this algorithm uses the rate of average residual error and the rate of average scatter coef-ficient constructed as the stopping criterion to terminate orthogonal matching pursuit ( OMP ) algorithm a-daptively. Meanwhile,the sparse reconstructed signals and the estimated sparsity of targets are obtained to improve the range resolution and obtain the targets' number. Simulation results verify the mainlobe broade-ning and the sidelobe crosstalk are suppressed by the proposed method and the range resolution is im-proved. In addition,the unknown targets' number is estimated accurately and the unknown targets' loca-tion is extracted by the proposed method in different noise conditions.关键词
