Abstract

Ground Penetrating Radar (GPR) antennas are often not well described and hence modeled in the majority of GPR simulators. As a consequence results from these models do not represent reality. In this paper two detailed Finite-Difference Time-Domain (FDTD) models of commercial GPR antennas are presented. The complex geometry, material properties and feeding of the antennas are all captured in the models. The Visualisation Toolkit (VTK) format has been utilised to enable powerful three-dimensional visualisations of the complex antenna geometries, in addition to the antenna field patterns. Initial results from free-space responses (crosstalk) show good agreement between the models and data taken from the actual GPR systems.
