Description

A 2D travel-time inversion algorithm that uses a recently developed fast-sweeping eikonal solver is presented. The algorithm is fast, extremely easy to implement, and robust. It is applied to borehole radar data collected in the karst aquifer at LSBB (Laboratoire Souterrain à Bas Bruit) and the recovered permittivity profile is shown to be consistent with borehole televiewer and material measurements.
