Ground Penetrating Radar: Background, Applications & Numerical Modelling

Nectaria Diamanti

Sensors & Software Inc., Mississauga, Ontario


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.



Nectaria Diamanti received both her B.Sc. in Geology and M.Sc. in Geophysics from the Aristotle University of Thessaloniki, Greece. In 2008, she obtained the Ph.D. degree in Engineering & Electronics from The University of Edinburgh, U.K. From 2009 to 2013 she was a Research Scientist at the Department of Geophysics, Aristotle University of Thessaloniki. Since 2013, she has been with Sensors & Software Inc., Canada, working in the area of ground penetrating radar (GPR) R&D and applications. Her main research activity involves application of geophysical techniques and especially GPR to geophysical/engineering problems. Her areas of research include: numerical modelling using the finite-difference time-domain (FDTD) technique, application of numerical modelling to GPR. She is a member of the Society of Exploration Geophysicists and of European Association of Geoscientists and Engineers.
