Abstract

Let D={(x, y) ∈ ℝ2 | x>0, y ∈ ℝ} and u(x, y, t) be the solution of an initial-boundary value problem for the two-dimensional wave equation in the half plane D. The half plane D carries a velocity stratification given by flat layers parallel to the boundary of the half plane characterized by a thickness and a constant velocity. We consider the following inverse problem: given the initial data, from the knowledge of u(0, 0, t), t>0, reconstruct the stratification. We give an algorithm to solve this problem based on an explicit formula for u(0, 0, t) and we report some numerical experience.
