Title: Method of acquiring vibroseismic data concerning a zone of the subsoil, and seismic exploration method including such a method

Abstract: The invention concerns a method of acquiring vibroseismic data concerning a zone of the subsoil. This method comprises the following steps: --operating a vibroseismic source so that it transmits a first vibroseismic signal having a first amplitude (101, 201), --operating the source so that it transmits a second vibroseismic signal having a second amplitude different from the first amplitude (103, 203), --recording first data corresponding to the first signal after propagation in the medium to be explored (102, 202), --recording second data corresponding to the second signal after propagation in the medium to be explored (104, 204). The method supplies information for filtering the surface waves (ground roll).
