1. A method for correcting for distortions in a seismic acoustic signal produced by a seismic vibrator immersed in a fluid, the method comprising:
determining a relationship between a pilot signal as a function of time q(t) and a wet volume as a function of time V(t); and
based on the determined relationship, applying a non-linear transformation, T, to the pilot signal so that the wet volume V(t) becomes a linear function of the modified pilot signal.
