Former Southwestern Proving Ground

Former Southwestern Proving Ground

Site Description

The former Southwestern Proving Ground (SWPG), near Hope, Arkansas, was used by the War Department as a test facility for ordnance during World War II. This demonstration was performed on Recovery Field 15 (RF 15) of SWPG.

Suspected Munitions Present at the Demonstration Site

20-mm, 37-mm, 40-mm, 57-mm, 75-mm, 76-mm, 90-mm, 105-mm, 120-mm, and 155-mm projectiles

81-mm mortars

Demonstration Summary

Both MetalMapper and TEMTADS 2x2 sensors were demonstrated in dynamic and cued mode on RF 15.  Each of the sensors was used on a separate part of the demonstration site with a small overlap area for comparison.  Far more anomalies were detected in the dynamic surveys than could be intrusively investigated within the scope of the demonstration so a sub-area was selected for each of the sensors for cued data collection.

Analysis of the data was performed using conventional and advanced data processing methods to select anomalies from advanced sensor dynamic data, and then extract features and perform anomaly classification on advanced sensor cued data.

The site was seeded with inert munitions, and all anomalies in the cued subareas were dug to confirm technology performance. Demonstrators are being 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.
