Abstract:

An Unexploded Ordnance discrimination study was conducted at the Former Camp San Luis Obispo SLO, California. The objective was to discriminate potentially hazardous 2.36 rockets and 60 mm, 81 mm and 4.2 caliber mortars from non-hazardous shrapnel, range and cultural debris. In this report, we describe the performance of twelve different discrimination techniques that utilized data from a number of sensors deployed in full coverage and cued interrogation mode. Two important conclusions can be drawn from the results presented here. Firstly, by appropriate use of discrimination metrics applied to production quality EM-61 data, it is possible to significantly reduce the number of clutter items excavated without missing any targets of interest. Secondly, the next generation of EM sensors, when deployed in a cued-interrogation mode, result in significant additional reductions in the number of clutter items excavated. Furthermore, the next generation sensors can usually distinguish different UXO types from one another.
