The US Army CECOM Acquisition Center-Washington intends to negotiate on a sole source basis with the Johns Hopkins University, Applied Physics Laboratory (JHU-APL) in Laurel, MD, a contract for a Time -Domain Electromagnetic Identification (TEMID) Sensor Technology Demonstration. This requirement is under the technical direction of the US Army CECOM Night Vision Electronic Sensors Directorate, S&T Division and is for an initial 24-month contract effort with a 12-month option. The proposed contract is a follow-on to JHU-APL's current effort started under contract DAAB07-97-C-6041 and will provide for the transition of the current proof-of-concept brassboard configuration to a vehicular mounted prototype demonstrator to find high- to-medium metallic mines, and a hand-held void detection demonstrator to find low metallic and plastic mines. Specific areas of development and test include: extending the frequency response of the sensors from 100KHz to 500KHz; improve sensitivity of the sensor for the detection of anti-personnel and anti-tank, plastic and metal landmines; target identification and three-dimensional (3-D) location algorithms by incorporating spatial magnetic field data from an array of magnetic sensors; adding in-field trainable identification algorithms, target database updates; integrating the breadboard metal target identification system onto a vehicular platform; and evaluating the electromagnetic induction time-domain concept for vehicle/soldier mounted both as a scanning sensor and a confirmation sensor. The electromagnetic time-domain induction technology operates on the principle of eddy current time decay. The time decay of a metal target's eddy currents is a function of the target's mechanical, electrical and magnetic properties. A target's identity can be determined by combining accurately measured time decay characteristics of the target with a time-constant/neuro-fuzzy classifier algorithm. The current proof-of-concept brassboard sensor configuration: (1) has been shown to detect and discriminate metal clutter targets from metal mines; (2) has been shown to be robust and rugged; (3) can maintain its operating efficacy and calibration under a wide range of environmental conditions such as military temperature ranges with nominal low-cost mechanical and electrical design considerations; (4) can automatically adjust for different soil types; and (5) detect plastic anti-tank mines in a range of soil types.
