Abstract: Based on a uniform linear L-typical signal received array and ESPRIT algorithm,a new separable method for estimating two dimensional(2 D) directions of arrival of multiple narrow-band spatial signals simultaneously is proposed in this paper.A paring method of azimuth and elevation of signals is given as well.Since the estimation of azimuth has the same architecture as the estimation of elevation of signals,it can be realized in parallel way.The simulation results on computer confirm its availability.
