N2 - In all matrix-pencil-based algorithms (the direct matrix pencil algorithm,ESPRIT, Pro-ESPRIT, and the state-space algorithm) the SVD (singular-value decomposition, or eigendecomposition) filtering approach has been used in several ways to reduce the noise effect and to transform a large matrix pencil into a smaller matrix pencil from which the wave directions are extracted. The SVD filtering approach to matrix pencil is presented in a unified way. Another prefiltering approach, which multiplies the large matrix pencil by a weight matrix before the SVD filtering approach is applied, is also presented. The weight matrix is based on the initial estimates, or the a priori knowledge, of the wave directions.
