Abstract
In weakly anisotropic VTI media, it is assumed that the ray directions of phase and group velocities are consistent, and P wave excites the horizontal interface, we take into account the equations between the anisotropic angle and the isotropic angle with the same horizontal slowness, and re-deduce AVO equations for VTI media again. The new equation shows that it has no effect on AVO equation for P wave, but improves AVO equation for SV wave.
