Resolution of prestack depth migration

Original language description

The resolution of a general 3-D common-shot elastic prestack depth migration in a heterogeneous anisotropic medium is studied approximately, using the ray theory. It is demonstrated that the migrated section can approximately be represented by the convolution of the reflectivity function with the corresponding local resolution function. Alternatively, it can also be approximately represented by the convolution of the spatial distribution of the weak-contrast displacement reflection-transmission coefficient with the corresponding local resolution function. The derived explicit approximate equations enable us to predict the migration resolution approximately without doing the whole and expensive migration. The equations are applicable to 3-D elastic migrations in 3-D isotropic or anisotropic, heterogeneous velocity models. Both the reflectivity function and the spatial distribution of the weak-contrast displacement reflection-transmission coefficient approximately determine the linear co
