Site Description

The former Camp Ellis Military Range (CEMR) is located in Fulton County, Illinois, between the towns of Ipava and Table Grove in western Illinois. The camp area covers approximately 17,455 acres, and the terrain of the former facility varies. Most of the former CEMR’s land area is used for farming, though some parts of the former site also are used as pastureland, and a few wooded areas exist in the northern portion. Most of the area is undeveloped, occupied by corn and bean fields. Some parts of the former cantonment area remain unfarmed because the thick concrete slabs used as building foundations are difficult to remove. Tree groves exist in other areas.

A subset of the Rocket, Rifle, and Hand Grenades Munitions Response Site (MRS) (Area A) was selected for the ESTCP study. Area A is located in the northwest quadrant of the former CEMR and consists of approximately 52 acres of primarily cropland.

Demonstration Summary

Two advanced electromagnetic induction (EMI) systems were used to collect data onsite. The commercial MetalMapper (MM) collected data in dynamic survey mode to detect anomalies on approximately five acres, followed by cued interrogation of the anomalies detected.

The Naval Research Laboratory’s (NRL) man-portable Time-domain Electromagnetic Multi-sensor Towed Array Detection System (TEMTADS) 2x2 array collected dynamic survey data followed by cued interrogation of the anomalies detected over one acre for comparison purposes. ARCADIS, a production firm, collected the data for each advanced system.

There are two facets to the data analysis for this demonstration. The demonstrator preprocessed detection survey data and, in conjunction with the Program Office, identified anomalies. The demonstrator then collected cued data and processed it through background subtraction and geolocation. The data analysis demonstrators employed physics-based models to extract target parameters and then classification algorithms to produce a ranked anomaly list.

The site was seeded with inert munitions, and all anomalies were dug to confirm technology performance. Demonstrators will be scored based on their ability to eliminate nonhazardous items while retaining all detected munitions. Results of the data analysis from this demonstration will be posted as they become available.
