GPRSIM is a completely interactive 2D forward modelling software designed specifically for ground penetrating radar.
Use GPRSIM to draw a cross-section of what you’re expecting to find below-ground. Specify some antenna parameters (e.g. frequency, time-window, samples per trace/scan, antenna geometry, etc.), soil and geological parameters (i.e. what sort of soil and rock is present, topography, etc.), and GPRSIM will produce a simulated radargram based on your drawn cross-section.
You can use GPRSIM in unusual scenarios where you’re not certain if ground-penetrating radar will be an appropriate tool, or if you’re not certain what a specific buried feature would look like in a radargram.
GPRSIM makes your GPR data interpretation easier.
GPRSIM predicts the full waveform of microwaves that are reflected, transmitted, refracted and attenuated across model ground structures.
You can also export simulated radargram files for processing in GPR-SLICE in order to e.g. export an entire simulated grid-based dataset in order to simulate depth-slices in GPR-SLICE.
The complete theoretical details of GPRSIM are available in a paper by Dean Goodman, published in the journal “Geophysics”, vol 59-2, p224-232, 1994.
