提出了一种Ｖ形阵列，它可以分解为两个一致位移子阵列．由子阵列信息可以形成混合波达方向矩阵．在无需谱峰搜索的条件下，对混合方向矩阵进行特征分解，可以获得信号的混合方向矢量和方向元素．因此可以估计出信号的二维波达方向．本文方法不仅保持波达方向矩阵方法的优点，而且在一定程度上可以分辨来自于同一方位角或同一高低角的信号． A V-shaped array is proposed, which can be decomposed into two uniform displacement sub-arrays. The sub-array information can form a mixed DOA matrix. Under the condition of no peak search, the mixed directional matrix is ​​decomposed to get the mixed direction vector and directional element of the signal. Therefore, the two-dimensional wave direction of the signal can be estimated. The proposed method not only preserves the advantages of the DOA matrix method, but also can distinguish the signals from the same azimuth or the same elevation from each other to a certain extent.
