Modelling programs are very useful tools for training in better understanding and interpretation of scanned underground images.
GPRSim.net is a basic GPR time domain simulation tool developed by Geoscanners AB.
It is partially based in the transmission line model and allows up to ten layers to be simulated
with frequencies ranging from 200 to 2000 MHz.
GprMax is a free Ground Penetrating Radar (GPR) simulator developed by Antonis Giannopoulos.
It is based on the Finite Difference Time Domain (FDTD) method. GprMax has 2D and 3D versions.
It will run both under Linux and MS Windows.
Recently we started to develop software with user graphical interface to prepare input data for modelling in GprMax.
Visualization of output model data created by GprMax is included to our program GprProfile.
