A simulation concept based on the FDFD method for ground penetrating radar used in humanitarian demining

In this paper a simulator based on the finite-difference frequency-domain method (FDFD) is presented, allowing an effective and accurate performance estimation of ground penetrating radar in humanitarian demining. After validating the implemented algorithm, the detectability of shallow buried improvised explosive devices (IEDs) is simulated and analyzed. The backprojection algorithm is used to compensate range migration of the ground echoes, improving the signal strength of the IEDs. Subsequently, the impact of surface roughness on the unfocused and focused echo profiles is investigated.
