摘要

在双平行线阵的基础上

提出了一种可在多径环境下估计二维波达方向的新算法.算法充分利用了信号在空间和时间上的特性

能估计的来波方向最多可达到(2

M-1)(M-1)(M

为天线阵元对数)

估计过程中不需要角度搜索和参数配对过程

而且能根据不同的用户对相干来波实现分组.仿真试验结果证明了这种方法的有效性.

Abstract

Based on two parallel linear arrays

a new algorithm of 2-D direction finding under multipath environment is proposed which can estimate (2

M-1)(M-1)(M

is the pair number of the arrays) directions at most

by sufficiently utilizing the temporal and spatial features of the signal

without the need of searching and parameter matching.In addition

this method can group the DOAs according to different users.Simulation results are provided which prove the validity.
