Paper Abstract

Ground Penetrating Radar (GPR) has been found to be a promising technology for detecting landmines. Landmines reflect electromagnetic energy in many directions, causing the GPR antenna to pick up these reflections at multiple positions with respect to the landmine. This decreases the resolution of the GPR image. Reflection seismology, which images the earth's subsurface using elastic rather than electromagnetic waves, experiences similar difficulties. Migration is a technique used in reflection seismology to address this problem. This paper present an adaption of the Gazdag phase-shift migration algorithm for use on GPR data in the context of landmine detection. The possible benefits of migrating GPR dat are more precisely locating mines and improved detection of mines with weak signatures. Landmine detection requires a real-time approach whereas reflection seismology performs migration after the data are acquired. The different scenarios of usage have significant implications on the form of candidate migration algorithms. The adapted algorithm was applied to GPR data acquired during test of the Mine Hunter/Killer system at Fort AP Hill. The results presented herein demonstrate the resolution enhancement potential of the proposed algorithm.
