MTADS TECHEVAL Demonstration

Abstract

Abstract : The Environmental Security Technology Certification Program (ESTCP) provided funding to the Naval Research Laboratory (NRL) for the development and demonstration of a Multi-sensor Towed Array Detection System (MTADS) for the detection and classification of unexploded ordnance (UXO). The MTADS incorporates both cesium vapor full-field magnetometers and active, pulsed-induction sensors. The sensors are mounted as linear arrays on low-signature platforms that are towed over survey sites by an all-terrain vehicle. The position-over-ground is plotted using state-of-the-art Real-Time Kinematic, On-the-Fly (RTK/OTF) resolution of integer ambiguities, a GPS technology that also provides vehicle guidance during the survey. Using mature sensor technologies, NRL has focussed on careful integration of the Data Acquisition System (DAQ) and development and integration of a sophisticated Data Analysis System (DAS). The DAS is designed to locate, identify, and categorize all military ordnance at its maximum probable self-burial depths. The DAS is efficient and simple to operate. The performance of the MTADS system has been evaluated during the course of a three-phase demonstration plan. The first of these was a technical evaluation (TECHEVAL) demonstration at the Naval Research Laboratory's Chesapeake Bay Detachment (CBD) in October 1996 to verify compliance with system requirements and performance specifications. This report summarizes the results of the TECHEVAL at CBD.
