Title (EN) DE-ALIASED SOURCE SEPARATION METHOD
(FR) PROCÉDÉ DE SÉPARATION DE SOURCES NON DÉFORMÉES PAR REPLIEMENT DU SPECTRE
Abstract: front page image
(EN) Methods are described for separating the unknown contributions of two or more sources from a commonly acquired aliased wavefield signals including the determination of models with reduced support in the frequency-wavenumber domain which reconstruct the wavefields of independently-activated sources after a coordinate-transform of the acquired wavefield data and/or in a coordinate-transformed domain.
(FR) Procédés de séparation des contributions inconnues d'au moins deux sources d’un ensemble de signaux de champs d'ondes non déformés par repliement du spectre et d’acquisition commune, comprenant la détermination de modèles avec un support réduit dans le domaine fréquence-nombre d'ondes qui reconstituent les champs d'ondes de sources activées indépendamment après une transformation de coordonnées des données de champs d'ondes acquises et/ou dans un domaine transformé en coordonnées.
