Scattering by Buried Obstacles
Abstract
The purpose of this investigation is to find theoretical solutions to scattering of electromagnetic fields by buried obstacles. The first part of the investigation is primarily concerned with the source problem of the scattering phenomena. It enables us to find the near fields of an antenna above a lossy ground and the near fields penetration into the ground, which are the primary fields to be scattered by the obstacles. In order to study that problem the Sommerfeld's integrals are extensively studied. The second part of the investigation involves some practical application of the results of the first part which have direct bearing on the 'detectability' of buried obstacles. The third part of the investigation contains the preliminary work of scattering by buried dielectric obstacles. Since the final objective of this research is the detection of buried dielectric bodies, the technique of computing dielectric scattering is of primary importance. The application of the 'Uni-moment method' to 2-dimensional scattering problems is presented.
