Abstract:

Ground Penetrating Radar (GPR) is a well-established method of investigation applied to various geophysical, geological and engineering problems, ranging from environmental monitoring and non-destructive testing to archaeological prospection and remote sensing. The fact that GPR signals are complex has led to the development of increasingly sophisticated numerical models to help progress understanding of how to detect, interpret and identify buried objects.

This talk will give a general background to GPR. Various case studies will be shown. In most cases, there are difficult problems to tackle regarding data interpretation. To better understand and interpret GPR complex signals, a complete GPR numerical model is needed. The application of numerical modelling to GPR will focus on the finite-difference time-domain (FDTD) method. Various numerical models will be shown which will allow the study of attributes of reflected signals from various targets.
