Abstract

In this work we provide an enhanced rule in order to model a buried object with a 2-dimensional symmetry by a wire-grid modeling for the Ground Penetrating Radar (GPR) archaeological applications. The buried object with a circular traversal section, is presented. The dependence of the rule as a function of the time and the frequencies, is presented. The validation was obtained using a numerical software based on the Finite Element Method (FEM) both in time and frequency domain and matching the results. We show how, the so-called equal-area rule (EAR), used in order to model the buried object with a wire-grid modeling, is optimizable changing the relative radii of the with respect to the canonical EAR.
