Abstract

Based on the MUSIC and ESPRIT techniques and using the signal temporal information

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.Simulation results show that the proposed method is effective.
