- W3146020677 abstract "Due to the effects of complicated subsurface structures and seismic acquisition systems, the seismic wave illumination to some subsurface targets may be inhomogenous, so the seismic acquisition system can not effectively acquire the reflected information from these targets, and migrated images of these targets will have some migration shadows. Based on the windowed Fourier frame expansion of wavefield and Green function, an illumination compensation method for wave equation migration shadow is proposed by using the wave equation migration and illumination analysis in angle domain and combining the wave equation inverse theory. The compensation method can take account into the effects of the seismic acquisition system and wave propagation path, remove the migration shadow on the complicated subsurface structures, and improve the results of wave equation prestack depth migration in complex structure regions." @default.
