  The work reported here details basic validation of our advanced physics-based
EMI forward and inverse models against data collected by the NRL TEMTADS
system. The data was collected under laboratory-type conditions using both
artificial spheroidal targets and real UXO. The artificial target models are
essentially exact, and enable detailed comparison of theory and data in support
of measurement platform characterization and target identification. Real UXO
targets cannot be treated exactly, but it is demonstrated that quantitative
comparisons of the data with the spheroid models nevertheless aids in
extracting key target discrimination information, such as target geometry and
hollow target shell thickness.
