基于Toeplitz重构的近场相干信号定位
Near-field Coherent Signal Localization Based on Toeplitz Reconstruction
摘要
Abstract
To solve the problem of locating narrowband coherent sound sources in near-field conditions,a near-field coherent MUSIC location method based on Toeplitz reconstruction is proposed.This method projects the covariance matrix of near-field re-ceived signals onto the covariance matrix of a virtual far-field uniform array,reconstructs the projected covariance matrix into a full-rank matrix,and then performs MUSIC-based direction-of-arrival(DOA)estimation.Simulation results demonstrate that the proposed algorithm can locate and separate closely spaced coherent sound sources under near-field conditions,achieve better perfor-mance than spatial smoothing algorithms in high signal-to-noise ratio scenarios without compromising the array aperture.关键词
