| Abstract: | Based on the MUSIC and ESPRIT techniques and using the signal temporal informati on,a new method with high precision is presented for simultaneous estimation of frequency and direction of arrival (DOA) of spatial coherent signal sources over a wide frequency band. By means of forming a so called smoothed DOA matrix,the estimated parameters of frequencies and DOAs are paired automatically.Simulatio n results show that the proposed method is effective. |
