Abstract

En fremgangsmåte for å identifisere en posisjon for en støykilde i en marin, seismisk registrering innbefatter å definere, for minst én skuddregistrering, et sett med mulige støykildeposisjoner. En differanse mellom forplantningstid for støy fra hver mulige støykildeposisjon til hver av et antall mottakerposisjoner for den minst ene skuddregistreringen, blir bestemt. Signaler fra minst et delsett av mottakerposisjonene blir tidsinnrettet med hensyn til differansen mellom forplantningstider for hver mulig støykildeposisjon. De tidsinnrettede signalene blir så stakket. Støykildeposisjonen blir bestemt fra de stakkede, tidsinnrettede signalene. Dette resultatet kan så brukes til å konstruere en modell av støyen ved mottakerposisjonen.
