Abstract
La présente invention se rapporte à un procédé de traitement de formes d'ondes, qui fait appel à la cohérence du signal des données de réseau pour traiter des signaux présentant un rapport signal sur bruit médiocre. Le procédé selon l'invention consiste : à transformer tout d'abord des données de formes d'ondes brutes en domaine f-k (fréquence-nombre d'ondes) ; à calculer ensuite une fonction de cohérence, et à la convolutionner avec les données du domaine f-k, ce qui supprime efficacement les signaux non cohérents contenus dans les données ; pour les données cohérentes restantes, à négliger la partie non désirée, à retenir la partie désirée, et à procéder à sa transformée inverse de manière que l'on obtienne des données de formes d'ondes de réseau à filtrage par cohérence. Un tel traitement permet d'extraire de petits signaux qui sont cachés dans les données originales avec une cohérence considérablement améliorée. Ensuite, le traitement des données permet d'obtenir des informations fiables relatives aux propriétés acoustiques de formations.
