Numerical studies of an adaptive finite element method applied to the reconstruction of shapes of buried objects from experimental data

Abstract

We perform extended studies of an adaptive finite element method applied to the reconstruction of shapes of buried objects from experimental backscattering data. We use experimental data which are collected by a microwave scattering facility located at the University of North Carolina at Charlotte, USA. Our numerical tests show accurate imaging of three components of interest of targets: shapes, locations and refractive indices.
