Canadian teleoperated landmine detection systems. Part I: The improved landmine detection project

The system developed under the Improved Landmine Detector Project is a teleoperated, multi-sensor, vehicle-mounted mine detector for low metal content and non-metallic mines to meet the Canadian requirements for rear area mine clearance in combat situations and peace-keeping on roads and tracks. The system consists of a purpose-built teleoperated vehicle carrying a forward looking infrared imager, a 3m wide, down-looking highly sensitive electro-magnetic induction detector and a 3m wide down-looking ground probing radar, which all scan the ground in front of the vehicle. Scanning sensor information is combined using a suite of navigation sensors and custom designed navigation, spatial correspondence and data fusion algorithms. Suspicious targets are then confirmed by a thermal neutron analysis detector. Key to the success of the system is the combination of sensor information, which requires coordinated communication between the sensors and navigation system and well designed sensor co-registration, spatial correspondence and data fusion methodologies. The advanced development model was completed in October 1997. Results are presented from Canadian and independent US trials in summer 1998. Four production units, based on the prototype technology, were delivered to the Canadian Forces in 2002, making the system the first militarily fielded, teleoperated, multi-sensor vehicle-mounted mine detector.
