I present the derivation in the midpoint-offset domain of two formulae approximating, for a shot receiver pair, the time of flight of acoustic signals traveling in a 2D inhomogeneous medium. The first expression assumes a flat acquisition surface, while the second, which generalizes the first one, takes into account the topography of the ground. The problem is first solved in an auxiliary homogeneous medium; the resulting time of flight is then delayed to be accommodated to the final velocity macro-model.
