Results and DiscussionEMI Signature LibraryA total of 2154 clutter items were measured during this project. Table 3 gives a summary. Themajority (1663) are from four sites used in the ESTCP Classification Pilot Program Live SiteDemonstrations: former Camp San Luis Obispo (Camp SLO) in California, former Camp Butnerin North Carolina, former Camp Beale in California, and the Pole Mountain Target andManeuver Area in Wyoming. Recall that 823 clutter items from former Camp Sibert weremeasured for SERDP project MR-1595.Site Number TypeCamp San Luis Obispo 700 Cultural & munitions debrisCamp Butner 448 Cultural & munitions debrisCamp Beale 208 Cultural & munitions debrisPole Mountain 307 Cultural & munitions debrisRemington Woods 475 Cultural & industrial debrisFort Bliss 16 Mortar fin piecesTotal 2154Table 3. Origin of clutter items in EMI signature library.The clutter from Camp SLO included a lot of mortar and rocket debris (Figure 10, left). Theother ESTCP live sites had significantly more exploded ordnance fragments. Examples areshown in the photographs on the right in Figure 10.Figure 10. Clutter from the ESTCP live sites.The Remington Woods site is a Brownfields Redevelopment project in Bridgeport, CT. It is thesite of a former Remington Arms plant where various small arms and explosive projectiles weremanufactured and tested. Several ESTCP and SERDP projects (MR-200108, -200909, -1310)16
