A permittivity range profile reconstruction technique for multilayered structures by a line process-augmented genetic algorithm

The paper presents a technique to reconstruct the permittivity range profile of a layered medium using noisy backscattering data. Working on an ill-posed problem, inverse scattering normally provides either unstable or over-smoothed results. Our method tries to obtain an accurate reconstruction using a two-step genetic algorithm employing a regularization constraint with an explicit line process and a local deterministic optimization strategy.
