Abstract :
A spatial smoothing preprocessing scheme for solving problems encountered in direction-of-arrival estimation of fully correlated signals is analyzed. Simulation results are presented, that illustrate this scheme in comparison with the classical MUSIC technique. Finally, an improved spatial smoothing algorithm, which has the ability to detect more coherent signals, is introduced and its behaviour in comparison to the previous techniques is examined by simulating specific cases.
