Abstract

Based on L-shape array, a novel method of 2-D DOA estimation by matrix enhancement and matrix pencil (MEMP) is proposed. Firstly, it computes the covariance matrix of output of the two linear arrays and constructs the enhanced matrix by MEMP method and then estimate the 2-D DOA by the ESPRIT method. Using a new algorithm makes the 2-D angles pairing automatically. To avoid the aperture decreasing, using fourth-order cumulant extends the MEMP method, the method increases the valid aperture of the arrays, without spectral peak searching. The effectiveness of the method is demonstrated through some simulation examples
