Paper Abstract

Higher order statistics heave been shown to be useful in applications where non-Gaussian or colored Gaussian noise is present. In this paper, fourth order cumulant-based MUSIC and matrix pencil-type algorithms were presented for the estimation of specular components in the acoustic backscattered data. Higher order Toeplitz matrices are formed from the sample cumulants and the generalized eigen- structure of these matrices are studied and exploited to develop high resolution estimators. The performance of these methods is examined on several data sets.
