摘　　要：提出了冲击噪声环境下双基地MIMO雷达多目标角度估计方法。基于传统的双基地MIMO雷达模型,推导了冲击噪声环境下双基地MIMO雷达模型,再将其转化为稀疏重构的问题,推导了冲击噪声环境下基于稀疏表示的双基地MIMO雷达模型,最后运用稀疏度自适应匹配追踪(Sparsity Adaptive Matching Pursuit,SAMP)算法求解模型。算法的优点有:不需要信号源个数作为先验信息,只需单快拍即可实现信号重构,能处理相干信号源,无需参数配对。仿真结果验证了算法的有效性。A new method of muhi-target localization for bistatic Multiple- Input Multiple-Output （MIMO） radar system in the Symmetric a-Stable （SαS） impulsive noise environments is presented. Based on the traditional bistatic MIMO radar model,the bistatic MIMO radar in the SaS impulsive noise environments model is given. Moreover,in order to use Sparsity Adaptive Matching Pursuit （SAMP）,the bistatic MIMO radar in theimpulsive noise environments based on the sparse representation model is given. The advantage of proposed method is that it doesn＇t need to know the number of signals,it only needs single estimated with simulation. snapshot,it works on coherent signals automatically. The effectiveness of the well,the transmit and receive angles can be proposed method is verified with the computer
