Direction-of-arrival estimation of coherent sources for ULA based on the relation between array covariance matrix elements

This paper presents a Direction-Of-Arrival (DOA) estimation method of coherent sources for Uniform Linear Array (ULA) based on the relation between array covariance matrix elements. First we analyze the covariance matrix in array signal processing and formulate the relations between the matrix elements. Then we develop a novel DOA estimation method of coherent sources for ULA based on the analyzed relations. Performance of the proposed method is evaluated through computer simulation.
