A new approach of 2-D MUSIC algorithm was proposed.Using the eigenvector and the eigenvalue of the co-variance matrix simultaneously

the method was composed of two one-dimension searching and avoided the costly 2-D searching.The pairings of the estimated parameters were automatically determined and the estimation precision was high.It was proved that the algorithm was valid even in the case that one of two parameters was same.Simulation results are presented to demonstrate the performance of the proposed method.
