Land Mine Detection
EG&G has been involved in land mine detection programs for over
a decade:
- In 1990 EG&G performed
work on Mirador, a mine detection sensor test bed;
- From 1993 through
1998, EG&G designed, developed, integrated, deployed and tested
a Vehicle Mounted Mine Detector (VMMD) system; and
- Since March 1999,
EG&G has held the GSTAMIDS Block 0 Engineering and Manufacturing
Development contract.
EG&G offers land mine detection
sensors developed for military applications, including:
- Ground Penetrating
Radar (GPR) – developed specifically for rugged, vehicular mounted,
military applications. Design optimized to provide adequate ground
clearance for both on and off road applications, while maintaining
sufficient depth penetration in both dry and wet soils, including
gravel, sand, clay and loamy soils.
- Pulsed Magnetic Induction
(PMI) Metal Detectors - developed specifically for rugged, vehicular
mounted, military applications. Design optimized to provide adequate
ground clearance for both on and off road applications, while maintaining
sufficient depth penetration. Built-in automatic static cancellation
techniques allow use while mounted on metallic platforms.
- Long Wavelength Infrared
(LWIR) Camera – adapted COTS cameras for rugged, vehicular mounted,
military applications. Installation design optimized for full swath
coverage, while eliminating shadow and glare reflection effects.
EG&G also has developed
both buried and surface mine feature algorithms and advanced sensor
fusion techniques to reduce FAR while maintaining a high Pd:
- GPR Algorithms – developed
multiple GPR feature extraction algorithms, ranging from simple
energy based blob detectors to Normalized Adaptive Matched Filter
(NAMF) based and advanced shape feature extraction algorithms.
- Metal Detector Algorithms
– developed advanced metal detector clutter rejection algorithms
that allow easy discrimination between battlefield and roadside
clutter from land mines.
- IR Algorithms – developed
robust IR image feature extraction algorithms, simultaneously processing
warm and cool images to minimize mine feature loss during thermal
crossover.
- Fusion – developed
robust fusion of multiple GPR features with IR images and metal
detector clutter discrimination.
EG&G has applied
these sensors and algorithms to develop the real time GSTAMIDS
land mine detection system for the US Army. The vehicular mounted GSTAMIDS
provides real time mine detection and marking while traveling at 8 kph.
The system is modular and both operable and maintainable by the soldier.
