| 摘 要： | ;针对任意平面阵列,提出了一种基于辅助阵元的二维波这方向估计算法.首先利用附加的一个辅助阵元及信号的空、时域信息,构造时空旋转矩阵实现对仰角的分离估计,再利用得到的仰角信息通过一维搜索获取方位角.与传统基于子空间的二维波达方向估计算法相比,该方法不需要进行二维谱峰搜索与参数配对,对阵元的幅相误差具有较强的鲁棒性,并具有...

| Abstract: | Based on auxiliary sensor,a 2-D DOA estimation algorithm is proposed for arbitrary planar array.By adding an auxiliary sensor and exploiting information of source in space-time domain,the space-time rotational matrix is formed to estimate elevation in advance.Thereby,the azimuth can be obtained by 1D search using the information of estimated elevation.Compared with the traditional 2-D DOA algorithm based on subspace,the algorithm does not require 2D searching and pair matching.It has high angular resolving ... |
