Abstract

Partikkelbevegelsessensorsignaler og trykksensorsignaldataene fra en slept, marin, seismisk streamer blir kombinert for å generere en oppadgående trykkbølgefeltkomponent og en nedadgående partikkelbevegelses-bølgefeltkomponent. Den nedadgående partikkelbevegelses-bølgefeltkomponenten blir ekstrapolert fra dybdenivået for mottakerposisjonen til dybdenivået for kildeposisjonen. Den oppadgående trykkbølgefeltkomponenten blir multiplisert med den ekstrapolerte, nedadgående partikkelbevegelses-bølgefeltkomponenten for å generere et første produkt. Så blir nte ordens overflaterelaterte multipler i trykkbølgefeltet iterativt beregnet ved å benytte et produkt av (n-l)te overflaterelaterte, multippelfrie data og den ekstrapolerte, nedadgående partikkelbevegelsesbølgefeltkomponenten. De beregnede nte ordens overflaterelaterte multiplene blir iterativt subtrahert fra det registrerte trykkbølgefeltet for å generere de nte ordens overflaterealterte multippelfrie dataene.
