Methods for locating and identifying buried assets are one focus of a large research project entitled 'mapping the underworld'. As of part of the project we are studying novel configurations for ground penetrating radar (GPR). There are two of important specifications for the GPR configurations: the bandwidth and the dynamic range. In this paper, the bandwidth and dynamic range of a GPR are investigated through simulations. Media that are typical of street environments were modeled is used in the simulations. A 2D ray-tracing model is used to simulate propagation in the ground to identify signal levels, bandwidths and dynamic ranges. A novel In-Pipe deployment and a conventional deployment scheme for GPR are examined using ray-tracing. Comparison of the results shows that the In-Pipe deployment scheme for the GPR has immediate advantages over the conventional one, in terms of having a wider available bandwidth and therefore resolution, and in having a lower dynamic range requirement.
