摘要
本文提出了一种以空间增益随机变化的方法来去掉相关信源之间的相关性 ,以获得对相关信源的DOA的估计 .该算法隔裂了天线阵元的损失数与相关信源数的直接关系 ,减少了天线阵元的开支 ,并且具有算法简单 ,运算量小的特点 .理论分析与计算机仿真表明该算法切实可行、有效并且易于实现 .
A method to eliminate the correlation of signal sources is proposed,which can help to estimate the signal sources' DOA through randomly changing the spatial gain.The expense of receivers are separated from the number of the correlative sources in this algorithm which greatly reduces the expense of receivers.The load of calculation is also light.Theoretical analyses and computer simulation verify that the method is practical,effective and easily achieved.
