A method of determining the far-field signature of the seismic wave produced by at least one marine seismic source (20) involving mounting pressure sensing means (2) on the or each seismic source (20) and taking account of both linear and nonlinear components of pressure measurements made by the pressure sensing means (2) to determine the far-field signature of the seismic wave. The invention covers the generation of a seismic wave from a single seismic source and an array of seismic sources and also relates to marine seismic source apparatus.

Procédé permettant de déterminer la signature de champ lointain de l'onde sismique produite par au moins une source sismique marine (20), qui consiste à monter un dispositif (2) détecteur de pression sur chaque source sismique (20) et à prendre en considération les composantes tant linéaires que non linéaires des mesures de pression effectuées par le dispositif détecteur de pression pour déterminer la signature de champ lointain de l'onde sismique. La présente invention concerne la génération d'une onde sismique à partir d'une seule source sismique et d'un ensemble de sources sismiques et concerne également un appareil de sources sismiques marines.
