Abstract

This paper addresses the problem of estimating the shape parameters of seismic wavefields in linear array for the separation of waves by exploiting the diversity of the polarization state and propagation velocity between wavefields. We propose a method based on the shiftinvariance properties of multiple wavefields impinging on a uniform linear array of sensors to separate different waves, by jointly estimating the velocity and polarization parameters. Furthermore, the surface waves are removed using a spatial filter specifically designed to exploit velocity and polarization of different waves. We introduce a model for wideband polarized signals received by an array of three-components sensors used as a framework for implementing the proposed algorithms. Examples on simulated and experimental data illustrate the applicability of the proposed methods.
