摘　　要：针对电磁矢量传感器阵列,提出了一种基于矢量平滑的相关源MVDR波束成形算法(VS-MVDR)。分析了基于矢量平滑的MVDR波束成形的解相干原理,并推导出了在单相关干扰源情况下VS-MVDR波束成形器的输出信干噪比,该算法适应用于任意的阵列结构且在多径传播的环境中具有更好的性能。仿真实验验证了算法的有效性。The MVDR beamforming algorithm for correlated signal with vector smoothing was proposed based on elec-tromagnetic vector sensor array. First, the decorrelafion principle of MVDR beamforming with vector smoothing was analyzed, and the output SINR of VS-MVDR beamforming in the presence of a single correlated interference was derived. The proposed algorithm is suitable for arbitrary array structures and has better performance in multipath propaga-tion. Simulation results are shown to verify the efficacy of the proposed algorithm.
