Abstract

Abstract

A method based on spatial filter preprocessing is presented to enhancethe resolution of the existing spectrum estimation algorithms. The effective signal-to-noise ratio (SNR) and the accuracy of autocorrelation estimation are significantly improved through use of this method. The method is applied to array processing in the signal snapshot case. Simulation results are presented to illustrate the improved performance achieved by the new method as compared with that obtained by the other existing algorithms.
