| Abstract: | For the estimation of two-dimensional(2-D) directions of plane wave arrival,the Y-shaped array is shown to have some evident advantages over other popular geometries.In this paper, a new direction of arrival(DOA) estimation method is proposed for Y shaped array. With the utilization of array geometry characteristics and spatio-temporal processing, this method provides a low variance estimate even if the signal-to-noise ratio(SNR) is quite low. |
