The aim of the course:
The aim of this course is to serve as an introduction to the Georadar forward problem. So, this course mainly presents modelling of ground penetrating radar data and gives Finite Difference Time Domain (FDTD) Method. Also, it is aimed to introduce FDTD and importance of Absorbing Boundary Conditions (ABC) in this modelling. In this course a brief introduction of the procedure for applying FDTD method to time-domain Maxwell equations is shown.
