Ultrawide-Band Synthetic Aperture Radar for Detection of Unexploded Ordnance: Modeling and Measurements
Electromagnetic (EM) scattering from subsurface unexploded ordnance (UXO) is investigated both theoretically and experimentally. Three EM models are considered: the multilevel fast multipole algorithm (MLFMA), the method of moments (MoM), and physical optics (PO). The relative accuracy of these models is compared for several scattering scenarios. Moreover, the model results are compared to data...

متن کاملMetal Detectors in Civil Engineering and Humanitarian Demining: Overview and Tests of a Commercial Visualizing System
After a brief introduction to Humanitarian Demining we will review the basic principles of the electromagnetic detection of metallic objects, especially induction devices (“metal detectors”), and see how they are applied in Humanitarian Demining and Civil Engineering, with emphasis on visualization techniques. We will then report on tests of a commercial “imaging metal detector” aimed at trying...

متن کاملTarget Shape Classification Using Electromagnetic Induction Sensor Data
Classification based on shape is central to the problem of discriminating between unexploded ordnance (UXO) and clutter. Most UXO fit a specific profile: they are long and slender with typical length-to-diameter aspect ratios of four or five. Most clutter items, on the other hand, do not fit this profile. Using electromagnetic induction (EMI) sensor data, we present a model-based estimation pro...
