Abstract
Supported by the Army Humanitarian Demining MURI, we most recently have focused on determining the unique strengths of passive IR sensing as a function of attribute diversity. Our initial findings identify polarimetric hyperspectral imaging.as a robust means to rapidly survey and detect partially exposed, non-metallic anti-personnel (AP) mines. We are investigating the discrimination gains expected from the combined polarimetric hyperspectral attributes under laboratory and field conditions. A principal components analysis of our earliest data indicates that this combination of attributes is about three times more effective in discriminating AP mines or mine-like materials than conventional hyperspectral sensing. In addition, we have uncovered a distinguishing spectral behavior of the Fresnel reflectance across resonance features that can be measured only by spectrally-resolved polarimetry.
