Abstract: Using three uniform linear arrays (ULAs), a high-resolution DOA matrix method is proposed for the two-dimensional (2-D) direction-of-arrival (DOA) estimation of multipath narrow-band coherent sources impinging on the far field of an antenna array. With the same eigenvector of the DOA matrix used to estimate the 2-D DOA, the method can automatically implement the pairing of estimated parameters and solve the angle overlapping problem of incident beams. The mean square error (MSE) of the 2-D DOA estimation is discussed. By simulations using Matlab software, the theoretical and experimental MSE curves are compared in relation to CRB, and the results show the proposed method has very high resolution with smaller error and it is applicable to multipath environment.
