Method for retrieving local near-surface material information

摘要

The invention concerns a method for retrieving local near-surface material information including the steps of:-providing a group of receivers comprising at least one buried receiver and at least one surface receiver positioned either at or very near the Earth surface;-recording a seismic wavefield;-estimating a propagator from said recorded seismic wavefield;-inverting said propagator; and-retrieving said near-surface material information.
