Abstract
En fremgangsmåte for fjerning av luftbølgeeffekt fra elektromagnetisk frekvensdomene-måledata i forbindelse med en styrt kilde til sjøs. Området av interesse blir modellert med (111) og uten (113) et øvre luftlag. Det elektromagnetiske feltet som skyldes kilden, blir beregnet ved målemottaker-posisjonene for hver kildeposisjon for begge modeller. Differansen mellom feltene som er beregnet (116) fra de to modellene, er luftbølgeeffekten som så blir subtrahert (117) fra feltdataene for den tilsvarende kilde/mottaker-geometri.
