F-K FILTRERING AV FLERE REFLEKSJONER FRA EN SEISMISK SEKSJON

摘要

Multiple reflections are filtered from seismograms by transforming them into an f-k array representing amplitude as a function of frequency and wave number. The inverse of the f-k transform of the multiple reflections is generated. The f-k array of the seismograms is filtered by weighting all samples with the inverse of the f-k transform of the multiple reflections.
