Approaches for GSLS based nearly constant- Q viscoacoustic wave equations and its application in reverse time migration calculated by finite-difference method

Abstract Seismic waves are attenuated and distorted during the propagation. The amplitude attenuation can decrease the energy of the wavefields, and dispersion effect distort the phase of seismic waves, thereby degrading the imaging resolution. In nearly constant-Q reverse time m...
