The basic objective of this research project was to develop an improved understanding of the fundamental physics underlying classification and discrimination of unexploded ordnance UXO and clutter items using electromagnetic induction EMI data. This improved understanding can help to establish a rational basis for the development and implementation of improved UXOclutter discrimination processing and analysis techniques capable of fully exploiting the capabilities of new EMI sensor technologies purpose-built for target classification. We proposed to assemble a comprehensive database of EMI signatures of UXO and clutter items from a variety of active clearance sites using the ESTCP MR-200601 time domain EMI array. The objective was then to work with this library to relate the structure of the EMI signatures to the fundamental physical aspects of the EMI response arising from the magnetic surface mode and the bulk eddy current decay regimes, and establish bounds on the information content of the EMI signatures in the two regimes and their significance for UXOclutter classification and discrimination.
