The goal of this lab is to get you to familiarize with coding wave propagation and reverse time migration (rtm). you will be given a module that contains all the necessary subroutines for rtm.

Reverse Time Migration Pdf Numerical Analysis Reflection Physics The viscoacoustic wave equation with decoupled amplitude attenuation and phase dispersion terms is convenient for implementing reverse time migration (rtm) in attenuating media. The paper puts forward the concept of multi scale grid for the underground medium based on finite difference time domain (fdtd) of reverse time migration (rtm), which can avoid the oversampling to high speed and hold the sampling density to low speed layer. Finally, based on the newly derived fd solvable pure acoustic tti wave equation, we implement tti reverse time migration (tti rtm). numerical examples demonstrate the eficacy of the proposed tti rtm scheme in correcting for anisotropic efects. As a result of the numerical performance of finite difference operators, reverse time migration (rtm) produces images which are typically low frequency or require large computational resources.
