Abstract
From the analysis of the direct path gain, this paper shows how it is possible to separate artefact effects from effects induced by the channel. The method proposed is based on the combination of the impulse response and the Wigner-Ville time frequency distribution. The article demonstrates the influence of swell on the travel delay of an underwater acoustic wave
