Antennas for Use in Ground-Penetrating Radars Designed for Landmine Detection

Abstract

The purpose of the research performed on this project was to investigate novel concepts for improving the performance of antennas for use in electromagnetic systems for detecting buried landmines This research covered four areas: i) The completion of a theoretical and experimental study of the resistively-loaded vee antenna for use in short-pulse, ground-penetrating radars. ii) A fundamental study of the coupling between antennas that are very close to the surface of the earth and shallowly buried mines. This study makes use of a plane wave spectral analysis that contains both propagating and evanescent waves. iii) An investigation of the conical spiral antenna in free space and over the surface of the earth. This antenna has broadband and directive properties that make it particularly attractive for the mine detection problem. iv) A fundamental study of the transient radiation of electromagnetic energy from simple wire antennas.
