Method for retrieving local near-surface material information

摘要

The invention concerns a method for retrieving local near-surface material information. According to the invention, the method comprises 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.
