Numerical Modelling of Ground Penetrating Radar Antennas

A036 NUMERICAL MODELLING OF GROUND PENETRATING RADAR ANTENNAS Introduction 1 Numerical modelling of ground penetrating radar (GPR) can significantly enhance our understanding of the GPR’s detection mechanism especially in complex environments. In addition models could aid GPR data interpretation. There are a number of numerical methods that can be used to develop a forward GPR model. One of the most versatile and powerful technique is the Finite-Difference Time-Domain (FDTD) method pioneered by Kane Yee (1966). FDTD has been used successfully to model GPR responses from simple targets assuming either a two dimensional or a three dimensional geometries (Holliger et. al.
