Abstract
Une séparation imparfaite au niveau des fréquences supérieures a été observée et a été finalement suivie jusqu'à un signal gfe médiocre qui est normalement utilisé dans l'inversion. L'invention utilise donc un « gfe dérivé » pour chaque source, obtenu par comparaison des enregistrements de tirs et élimination des différences, au lieu du signal gfe estimé antérieur délivré par l'organe de commande, ce qui permet de maximiser avec précision la séparation des données.
