Paper Abstract

An efficient direction of arrival estimation method for wideband uncorrelated and coherent signals is proposed with a uniform linear array. Firstly, uncorrelated signals are resolved by applying a test of orthogonality of frequency subspaces method (TOFS). Secondly, at each frequency bin, the contributions of uncorrelated signals and noise are eliminated and a new matrix is formed. Then, forward spatial smoothing technique is performed on the new matrices and coherent signals are resolved with TOFS. The method can resolve more wideband signals than the array elements. Simulation results demonstrate the effectiveness and efficiency of the method.
