摘　　要：论文针对空间平滑算法无法在有限阵元数目下实现多相干信号源的测向等问题,提出一种基于改进的空间平滑算法,仿真结果表明该算法可以降低对DOA估计对阵元数目的要求,并且还适用于非相干、相干和混合信号源等的复杂多信号环境。Aiming at the problem that common spatial smoothing can not conduct direction-finding to multiple coherent signalsources in limited quantity of array element,this paper provides one improved spatial smoothing algorithm. Simulation results indi-cate that the proposed algorithm can decrease the requirement by DOA estimation to array element quantity,and it can be employedin complicated multiple-signal environment consisting of non-coherent signal sources,coherent signal sources and mixed signalsources etc.
