Abstract

Recently, we have successfully applied the Elliptic Systems Method to inverse problems in laser medical imaging applications. As part of applying this method to mine detection, accurate and fast algorithms are required for solving the forward problem to generate data for the inverse problem. Results for the 2D forward problem using GMRES method are compared with 1D transmission line models. Simulation result for miens and clutter are provided for both methods. The comparison with 1D results suggests that GMRES is an effective approach to modeling the forward problem in mine detection. In addition, the contrast between results for mines and clutter provide useful signal features for initial screening between mines and clutter.
