Abstract
The multisensor towed array detection system (MTADS) provides the capability for rapid, efficient detection of buried unexploded ordnance (UXO). The system consists of two arrays of sensors, total-field magnetometers and time-domain, pulsed-induction sensors, coupled to an extremely precise GPS location system Data collected in the field are transferred to a workstation-based data analysis system for analysis. Anomalies are selected interactively by an operator and fit to a physics-based model. The MTADS has been demonstrated at several prepared rest ranges and two live sites. In all cases, probabilities of detection of greater than 95% have been achieved. The outstanding research issues in this program involve discrimination between UXO and fragments and scrap. Up to two thirds of the costs of a remediation effort result from digging holes that do not contain UXO. Even small improvements in classification ability will lead to large savings in real world operations.
