Approximate Identification of Boundary Properties in a Wave Equation by Optimal Control Techniques

PDF Version Also Available for Download.

Description

We apply optimal control techniques to find approximate solutions to an inverse problem for the acoustic wave equation. The inverse problem is to determine the shape and reflection coefficient of a part of the boundary from partial measurements of the acoustic signal. The sought functions are treated as controls and the goal is to drive the model solution close to the experimental data by adjusting these functions.
