Abstract: This research project is concerned with the problem of imaging shallowly buried objects. The primary application that will be addressed is that of land mine detection. The research effort differs from previous studies not only in its use of Electrical Impedance Tomography (EIT) as a rather unconventional imaging modality, but equally well in its consistent emphasis on tomographic imaging. When compared to the more common methods, based on single soundings, this should lead to a significant higher detection confidence. Up to now, tomographic imaging has only raised moderate interest in subsurface imaging, mainly due to its high computational demands. Therefore, the main contribution of this study will be the development of computational efficient and numerical reliable algorithms.
Although this project will concentrate on Electrical Impedance Tomography for the detection and imaging of shallowly buried objects, it should be emphasized that the detection probability and the rejection of false alarms, may be envisaged to be too low for most applications if EIT is used as a stand-alone technique. The current research should instead be seen as part of more global activities (e.g. VUB-ETRO research on humanitarian demining) aiming at the design of multisensor probes and the use of data fusion, integrating measurements coming from various sensors and being based on different physical principles.
