Subsurface illumination and propagation in Ground Penetrating Radar

It is desirable for ground penetrating radars to accurately determine positions of buried objects. This paper uses a combination of a ray-tracing technique and the finite difference time domain technique to assess the performance of a novel deployment strategy for ground penetrating radar where the transmitter is placed in an available structure underground. Promising characteristics are seen offering operation of the radar with lower dynamic range and higher bandwidths. The deployment system also appears to offer satisfactory illumination over a relatively large area.
