Distributed Radio Frequency RF Tomography is a novel approach for detecting underground tunnels and caves over relatively wide areas. This method requires a set of affordable transmitters and receivers randomly deployed above the ground. Using the principles of inverse scattering, it is possible to develop a simplified theory for imaging below ground, thus revealing and locating voids. In this paper, we introduce inversion schemes suited for ground penetrating radar tomography applied to sensors that are randomly distributed over the area of interest.
