单快拍虚拟阵列Toeplitz矩阵重构的相干信源DOA估计
Coherent signal source DOA estimation based on single snapshot virtual array Toeplitz matrix reconstruction
摘要
Abstract
Aiming at the DOA estimation of the coherent signal source,a decoherent algorithm based on single snapshot vir-tual array Toeplitz(SSVT)matrix reconstruction is proposed. The method uses the single snapshot data received by the array ele-ment to construct the bidirectional virtual submatrix. The Toeplitz matrix reconstruction is performed for the mean value of the co-variance matrix of the virtual submatrix to estimate the DOA of the coherent signal source. It is unnecessary for the method to conduct the multiple snapshots,and can estimate the DOA of the coherent signal source on the basis of ensuring the array aper-ture and work array element. The simulation results show that the algorithm can reduce the computation,and distinguish the M-1 coherent signal sources in the case of low SNR.关键词
