High-Resolution Pulse Based UWB Subsurface Interrogation

Description

In this contribution the general principles of pulse-based Ultra-Wideband (UWB) subsurface interrogation will be explained. The presentation deals especially with theoretical investigations on UWB radar systems, pulse-based UWB hardware components, signal processing techniques and applications of pulse based UWB subsurface interrogation. A ground penetrating radar (GPR) application for the detection and classification of non-metallic anti-personnel mines (APMs) buried beneath the surface will be presented. The hardware components, especially the pulse generator, the broadband double ridged horn antennas and the low noise amplifier (LNA) of the measurement setup will be described in detail. One of the most challenging tasks of the following signal processing is the removal of any disturbing ground clutter. Therefore an adaptive ground clutter removal (AGCR) algorithm for this application will be compared to standard ground clutter removal algorithms by means of real measured data with different ground material like gravel or sand and varying water content. Furthermore the differentiation of mine-like and non mine-like targets and the classification of APMs using their characteristic impulse responses will be shown. Finally, some other possible applications of pulse based UWB radar and communication systems especially for medical devices will be presented.
