We propose a new moveout approximation based on an alternative background model. The standard approach is based on elliptical background model with two velocities, vertical and normal moveout ones. We suggest to use another elliptical background model defined with vertical and horizontal velocities. We start with transversely isotropic medium with a vertical symmetry axis (VTI) and extend this approach to orthorhombic (ORT) medium. In order to stabilize the perturbation series, the Shanks transform is applied for the cases. The new moveout approximations result in better accuracy comparing with the standard perturbation based methods.
