Title (EN) SEISMIC ACQUISITION AND FILTERING
(FR) ACQUISITION ET FILTRAGE SISMIQUES
Abstract: front page image
(EN)An iterative process is described for obtaining a finite impulse filter to remove noise from seismic data through an iterative process with constraints on the filter applied in both, the original space-time and the transform frequency­wavenumber at each iteration step.
(FR)L'invention concerne un processus itératif qui permet d'obtenir un filtre à réponse finie permettant de supprimer le bruit dans les données sismiques grâce au procédé itératif, avec des contraintes dans le filtre appliquées dans l'espace-temps original et la forme d'ondes de fréquence à chaque stade de transformée.
