Analysis and Application of a Vehicle Mounted Ground Penetrating Radar Array

摘要

Ground Penetrating Radar (GPR) is an established technology for detecting anomalies beneath the surface of the ground. GPR systems currently in use tend to be hand held or trolley mounted devices that can be moved smoothly over the surface with little or no stand off from the ground and normally have a single transmit/receive antenna pair. However, these properties are quite different from the requirements of a vehicle mounted system such as track width coverage, variable ground clearance and a noisier environment. This paper, based on Countermine research carried out by the UK Defence Science and Technology Laboratory (Dstl), details the development and application of a military, vehicle mounted GPR system. Requirements of a vehicle mounted system are outlined and research towards creating a multi-antenna, vehicle mounted technology demonstrator is discussed. The paper also examines methods of data representation for GPR systems and the advantages that can be gained in this area using a multi-antenna array such as enhanced imagery and three dimensional reconstruction of objects beneath the surface.
