摘    要:提出了一种基于多窗方法的DOA估计算法,该方法只需要较少的快拍数目,能同时分辨相干信号和互不相关的信号.该方法以多窗函数为基础,将线性回归模型用于空间谱中平面波的检测和估计.计算机仿真结果表明该算法是有效的,甚至在低信噪比条件下仍然适用.然而,最值得注意的是,该算法对于阵列增益和相位误差具有较强的鲁棒性能.

关 键 词:多窗方法  波达角估计  线性回归模型

Abstract:An algorithm based on multi-window method which can achieve the efficient direction finding with a few snapshots in coherent or uncorrelated case was described.The proposed algorithm applies the linear regression model to checking and estimating existing plane waves in the spatial spectrum with multi-window functions.The computer simulation results show that the new method is effective even in low signal-to-noise ratio(SNR) situations.However,the most attractive characteristic of the provided method is that...
Keywords:multi-window method  direction-of-arrival estimation  linear regression model
