Abstract

SUMMARY

A modelling framework for realistic ground penetrating radar simulation in complex environments is presented. This approach incorporates detailed models of ground penetrating radar transducers as well as realistic descriptions of the underlying media and targets. The simulation of air-coupled horn antennas is presented and their performance is evaluated and compared to results from ground coupled bowtie antenna designs. The application of the modelling process to an engineering problem in pavement evaluation is discussed.
