The multisensor towed array detection system (MTADS) was designed to be an
efficient, sensitive tool for the detection and characterization of buried
unexploded ordnance, It comprises arrays of total-field magnetometers and t
ime-domain electromagnetic induction (EMI) sensors, associated navigation a
nd data acquisition hardware, and a custom Data Analysis System. The MTADS
has conducted eleven demonstrations and surveys over the past four years, T
he system has shown the ability to detect ordnance at its likely self-penet
ration depths with a probability of detection of 0.95 or better. The model-
derived positions and depths of the detected ordnance items are generally w
ell within the physical size of the targets, making remediation much quicke
r and less costly than with standard techniques. Data sets corresponding to
many of the MTADS surveys are available to others in the field.
