A Scattering Model for Detection of Tunnels Using Video Pulse Radar Systems.
Abstract
Various cylindrical scattering models are used to outline the expected performance of video pulse radar systems for the detection of buried tunnels. A new scattering model is introduced which treats the tunnel scattering in terms of a Scattering Attenuation Function (SAF) separately from the transmission between dipole antennas in the earth, which is discussed in a previous report. Examples of Scattering Attentuation Functions are given for buried conducting cylinders, lossy cylinders, hollow cylinders (tunnels), and infinite tunnels containing conducting wires insulated from the surrounding earth. The features of these results and their influence on the choice of the radar parameters to detect the various geometries are discussed. Results are also presented for finite length tunnels containing conductors, and it is shown that the video pulse radar is inherently suitable for detecting such targets. Features of the results which would provide an identification capability are discussed. (Author)
