The Naval Research Laboratory is developing a Multi-Sensor Towed Array Detection System, MTADS, for ordnance detection and site characterization. One component of this task is construction and validation of algorithms for target characterization and location for use in the data analysis system. In support of this task, we have collected an extensive set of ordnance signatures using total field magnetometers, total field magnetometers deployed as vertical gradiometers and specially modified Geonics EM-61 pulsed induction sensors. The ordnance items characterized range from Mk 42 submunitions to Mk 82,500 lb bombs at depths ranging from the surface to 20 ft. Where appropriate, signatures are recorded as a function of azimuth and inclination. We discuss the details of the sensor systems and the data collection methodologies. Typical signatures are presented and compared to simple models. We anticipate that this data set will become one of the standards for passive and active sensor algorithm development and training in the ordnance detection community.
