Abstract

The invention relates to a method of reducing the harmonic noise in a vibroseismic signal recorded by a sensor, said vibroseismic signal corresponding to a given vibratory sequence emitted by at least one source and propagated in a subsurface in which it is reflected. The invention is characterised in that the it comprises the following steps consisting in: (a) correlating the vibroseismic signal, or part thereof, with a signal corresponding to the fundamental component of the sequence of vibrations emitted by the source (20); (b) from the correlated signal, selecting one part which corresponds to the energy of the fundamental component of the vibroseismic signal (30) and applying an estimation operator of the harmonic component of the correlated signal to said selected part (40); (c) deducing therefrom an estimation of the harmonic noise of the vibroseismic signal and subtracting said estimation from the signal (50).
