Early-arrival waveform inversion for near-surface velocity and anisotropic parameters: inversion of synthetic data |

where and are horizontal and vertical stress, respectively, is vertical p-wave velocity, and and are anisotropic parameters (Thomsen, 1986).

The velocity parametrization defines the model space as follows:

The logarithmic slowness parametrization defines the model space as follows:

The non-linear conjugate gradient method is used for the inversion.
