Evaluation of the Multi-Sensor Towed Array Detection System (MTADS) Performance at the Marine Corps Air Ground Combat Center (MCAGCC), Twentynine Palms, California
Abstract
In December 1996, on the Magnetic Test Range at the Marine Corps Air Ground Combat Center, Twentynine Palms, California, the Multisensors Towed Array Detection System (MTADS) underwent its first semi-blind field test. After completing the data acquisition and determining the location of potential ordnance, the Institute for Defense Analyses performed an assessment to determine overall detection performance and unique characteristics of the MTADS. The detection rates for both the magnetometer and the electromagnetic induction system exceeded 80 percent with approximately 30 and 20 false alarms per acre, respectively, for the two detection systems. The magnetic gradiometers exhibited somewhat poorer detection performance than the other two sensor systems. The MTADS also demonstrated excellent accuracy when determining the location and depth of the ordnance. All three sensor arrays exhibited better than 40 cm mean location error and less than 20 cm mean depth error. The data collected at Twentynine Palms was also used to test a magnetic clutter discrimination algorithm based on the relative contribution of induced and remanent magnetization. Employing this algorithm resulted in at least 30 percent fewer false alarms, with minimal loss of unexploded ordnance detection capability when using the magnetometer.
