Based on Evans spatial smoothing preprocessing scheme, a new approach aalled two-direction spatial smoothing preprocessing method is presented. It is proved that the decor-relation, the effective aperture and the maximum number of distinguishable coherent signals (when array size is given) of the new method are better than those of the Evans method. Simulation results give a comparison between the eigenvector spectrums produced by the two methods.
