Characterization of a Two-Dimensional Subsurface Object with an Effective Scattering Model

摘要

In this paper, we consider the problem of an effective parametric characterization of a two-dimensional subsurface object from a limited set of measured scattered electromagnetic field data. Another important question which we address in our work is the practical real time applicability of the algorithm. Such an algorithm must be fast enough to be useful, for example, in land-mine detection. In the present paper, the unknown object is supposed to be located into a lossy half-space. We show how the structure of the background media can be taken into account within concepts of the T-matrix approach, so that previously developed results of the approximate T-matrix are easily extended to the present case.
