A MUSIC likeDOA estimation methodforsignals
YongjunZhaoandZhigang Wang JinWang · 2008
Anewkindofnoise subspace baseddirection-of- arrival (DOA)estimation methodisproposed. Unlike theMUSIC algorithm ,thenovelMUSIClikemethodusesignal subspace estimated byMulti-Stage WienerFilter (MSWF)instead ofarray steering vectors fororthogonality test. Simulation showsthatthe proposedmethodoffersimprovements in precision and resolution performance forsignals withlowSNR,compared to MUSICandESPRITalgorithms.
