GPRSim.net is a basic GPR time domain simulation tool. 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.

The program may be used to try out different real world survey scenarios and understand how different center frequency antennas could perform, as well as getting an idea of how the ground penetrating radar A-scan might look like in the given conditions.

All layers are defined using only three parameters: relative dielectric constant or permittivity (epsilon), electric conductivity (sigma) and the physical thickness of the layer. Instead of the electric conductivity (sigma) it is possible to enter the value for the loss tangent. The model assumes the relative permeability is equal to one.

The results of the simulation are displayed in the time and frequency domains and it is possible to print out the time domain plot. Different survey scenarios can be stored as csv files for quick access.
