Abstract
Summary
The generalized moveout approximation becomes a powerful tool for velocity analysis and time-domain imaging. The approximation parameters are computed from zero-offset ray and one reference ray. Using the same rays, I suggest changing the parameter selection by putting more fit to the reference ray. Analysis performed on analytical models shows that the new approach results in better accuracy for anisotropic velocity models.
