- W2357007389 abstract "This article firstly summarizes several amplitude-preserving prestack migration methods.As they consider different affecting factors they use different weight functions.The first weight function does not consider the affection of the migration aperture and caustic.The second function only considers caustic.The third weight function considers not only aperture but also caustic.The fourth weight function is based on wave equation.It is derived according to the imaging condition by decomposing upgoing wavefield and downgoing wavefield.Then the validity of amplitude-preserving migration is proved by the model,which shows the compensation effect of amplitude-preserving migration on the amplitude.Finally the relationship between the migration aperture and weight functions are discussed.It is mainly controlled by a continuous taper function to remove noise effectively during migration." @default.
