摘要
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．
This paper presents a V shaped array composed of two identical translation subarrays carrying the information by which the Mixed DOA Matrix can be formed. Eigendecomposing the Mixed DOA Matrix, 2 D direction of arrival of signals can be estimated. This method not only holds the advantages of the DOAM method but also to some extent resolves the signals coming from the same azimuth or elevation.
