METHOD AND APPARATUS FOR FREQUENCY DOMAIN REVERSE TIME MIGRATION WITH TRANSMISSION SOURCE ESTIMATION USING SEISMIC IMAGING

摘要

PURPOSE: A method and apparatus for frequency domain reverse time migration with transmission source estimation are provided to actually generate an underground image from modeling parameters which are calculated through waveform inversion.;CONSTITUTION: A transmission source estimating unit(100) estimates a transmission source from measurement data which is measured from a receiver. A structural migration unit(200) receives the transmission source from the transmission source estimating unit and processes reverse time migration. The transmission source estimating unit estimates the transmission source with the least squares method at a frequency domain.;COPYRIGHT KIPO 2012
