| 摘 要： | 介绍了一种新的非相干分布源的2D-DOA与角度扩展估计方法。该方法根据非相干分布源协方差矩阵的结构特点,将协方差分离成两个分别由相位信息和幅度信息重建的矩阵。从相位信息中利用传统的点源方法即可估计得到2D-DOA;从幅度信息中借助特殊阵列结构设计,即可实现角度扩展的估计,从而实现非相干分布源的2D-DOA与角度扩展分离估计。计算机仿真验证了算法的性能。

| Abstract: | According to the structure covariance matrix,the covariance matrix can be separated into two matrices rebuilt by phase information and amplitude information,respectively.The 2D-DOA could be estimated from the rebuilt phase information matrix by using traditional methods.Based on specially array geometry designation,the angular spread could be estimated by substituting the estimated DOA into the amplitude information vector.Thus such separation realizes separable estimations of 2D-DOA and angular spread for ... |
