Man-Portable Vector EMI Sensor for UXO Contamination Assessment at Munitions Sites

MR-201158

Demonstration Summary

Many Department of Defense (DoD) sites contaminated with munitions have terrain and vegetation that limit access of traditional large wheel-based sensor systems. Additionally, dense forest or significant topography can reduce the accuracy or preclude use of standard geo-location methods such as satellite-based global positioning system (GPS) and laser tracking systems that rely on line of sight. As part of the live site demonstrations, this project will demonstrate the utility of the novel Man Portable Vector (MPV) handheld sensor, which was developed by CRREL with SERDP and ESTCP support, to overcome these challenges. The MPV can deploy as a single-pass detection and discrimination system for small sites or for cued-interrogation with fast target re-acquisition. Superior signal sensitivity enables the system to locate a target's origin and provide immediate feedback on data quality, which allows the operator to optimize the data collection by adapting to site conditions and target response. This ensures that sufficient data are acquired for classification, thus saving time and costs of resurveying anomalies or excavating non-UXO items. If successful, significant productivity gains can be achieved from increased sensitivity, improved geo-location, and real-time feedback for data and survey optimization.

Technology Description

The MPV is a handheld, programmable, wide-band, time-domain, electromagnetic induction (EMI) sensor comprised of one transmitter loop and an array of five multi-component receivers. The sensor is deployed in cued interrogation survey mode with a beacon receiver boom: a local, portable positioning system that monitors the MPV transmitter field and returns MPV location with 1-centimeter and 1-degree accuracy within a range of 3-4 meters. Unlike a fixed template, this MPV-specific device allows users to adapt their survey to target response and environmental conditions. It is expected that approximately 100 anomalies per day can be characterized in cued-mode.
