摘　　要：提出了一种改进单通道接收机波达方向估计的超分辨解决方案。该方法通过对任意阵列实施变换,将实际的传感器阵列扩展成多个具有不同阵列孔径的虚拟阵列,有效地增加了阵元数目,提高了空间谱估计的分辨率,增加了可检测信号源数目以及阵列的解相干能力。通过理论分析和仿真实验验证了该方法的有效性和优良性。A modified single-channel receiver DOA estimation of super-resolution solution was proposed. By transformation of the arbitrary array, the method expanded the actual sensor array into several virtual arrays with different array aperture. This in- creased the number of elements effectively to enhance the spatial spectrum estimation resolution, and thus increased the number of signal sources and enhanced coherent capacity of the arrays. Theoretical analysis and simulation results show the effectiveness and fine sexual of the method.
