Title: Extraction de dispersion automatique de signaux acoustiques multiples se chevauchant dans le temps
Inventor: AERON SHUCHIN
IPC: G01V1/40
Filed: 2009-12-22
Granted: 2015-10-06
Abstract: La présente invention concerne des caractéristiques de dispersion de lenteur de signaux d'interférence éventuellement multiples dans des ondes acoustiques à large bande, tels que reçus par une matrice de deux capteurs ou davantage, extraites sans l'utilisation d'un modèle physique. On établit une correspondance entre le problème de l'extraction de dispersion et le problème de reconstruction de signaux possédant une représentation rare dans un dictionnaire exhaustif d'éléments de base, choisi de manière appropriée. L'invention porte également sur un algorithme de reconstruction de signal pénalisé de rareté, les contraintes de rareté étant mises en uvre par l'imposition d'une pénalité de type de norme l1. Les modes candidats qui sont extraits sont consolidés au moyen d'un algorithme de groupement afin d'extraire des estimations de lenteur de groupe et de phase à un certain nombre de fréquences, qui sont alors utilisées pour reconstruire les courbes de dispersion désirées. Ces estimations peuvent ensuite être affinées grâce à la construction de propagateurs de domaine temporel lorsque l'on sait que les signaux sont compacts dans le temps, par exemple en utilisant la transformation en ondelettes continues.
