Abstract: To estimate the Direction of Arrival (DOA) of coherent signals accurately and quickly, a new decorrelation method based on spatial smoothing technique and eigen space multiple signal classification (MUSIC) is presented. After spatial smoothing of the coherent signals, the eigen space MUSIC algorithm is applied to estimate the DOA in order to make maximal use of the information of signal and noise subspaces. In addition, the DOA estimation of uncorrelated signals is not affected, as well as the power of signal sources can be estimated effectively, which can improve the probability of success in the estimation of low power signals. The proposed method possesses a better resolving ability and a lower SHR threshold than conventional spatial smoothing technique and modified MUSIC algorithm for DOA estimation of coherent signals. The simulation results demonstrate that the proposed method is effective and robust in DOA estimation.
