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).
