METHOD AND APPARATUS FOR REVERSE TIME MIGRATION IN A TIME DOMAIN THROUGH TRANSMITTING SOURCE ESTIMATION CAPABLE OF GENERATING AN ACTUAL UNDERGROUND IMAGE FROM A MODELING PARAMETER CALCULATED THROUGH WAVEFORM INVERSION

摘要

PURPOSE: A method and apparatus for reverse time migration in a time domain through transmitting source estimation are provided to improve clarity of a reflective side in a final image when a transmission wave form, which is reversely calculated, is used.;CONSTITUTION: A transmission source estimating unit(100) reversely calculates a transmission wave form from measurement data measured from receivers and estimates a transmission source. A migration unit(200) receives the sender identification estimated from the transmission source estimating unit and processes reverse time migration in a time domain. The transmission source estimating unit produces a linear matrix equation, which is composed of a Toeplitz matrix and a cross correlation matrix of actual measuring data and a green function, with a Levinson recursion method.;COPYRIGHT KIPO 2012
