摘要/Abstract

摘要： 利用均匀线阵,本文提出了一种有效的相关噪声下宽带相干信号DOA估计算法.首先,在各个频率点,利用空间差分技术消除色噪声分量,并通过平方操作构造新矩阵;然后,通过聚焦操作得到通用的协方差矩阵;最后,通过使用传播算法估计得到宽带相干信号的DOA.算法能够分辨的相干组中相干信号的个数可以是奇数或是偶数.仿真结果验证了算法的有效性和性能.

Abstract: In this paper,we propose an efficient direction of arrival estimation method for wideband coherent signals in the presence of correlated noise with uniform linear array.Firstly,the component of correlated noise is eliminated by using the spatial differencing technique and then a new matrix is constructed by performing the squaring operation at each frequency bin.Afterwards,a universal covariance matrix is obtained by performing a focusing operation.Finally,the coherent signals are resolved by applying the propagator method.The signal number in a coherent group resolved by the proposed method can be even or odd.Simulation results demonstrate the effectiveness and performance of the proposed method.

Key words: wideband coherent signal, direction-of-arrival estimation, uniform linear array, spatially correlated noise, propagator method
