Expendable Metal Detector

Reference#: P02102


Improvised Explosive Devices (IED) is a problem in some war zones. The IED is commonly a bomb made of any type of available ordnance and detonated by remote control. The IED is varied and can be made from clusters of mortar shells or a single artillery shell. The IED is commonly placed along side a road and detonated when a vehicle drives by. The IED is commonly camouflaged by rocks or is buried in the ground. A need exists to detect

The Johns Hopkins Applied Physics Lab has invented and is in the patent process an expendable metal detector (EMD). The EMD consists of a launcher device, a metal detection device and a control box. The launcher propels the EMD metal detector to the location of the suspected IED. The launcher device could be a crossbow-like device, a pneumatic canon or shotgun. Also, for the passive EMD version, the EMD could be thrown by hand by the user toward the suspected IED. There are two basic EMD metal detector configurations, passive and active metal detection. The passive metal detection technology uses conventional magnetometer gradiometer technology with a novel deployment configuration. The active metal detection method uses conventional pulse metal detection technology with a novel deployment and mechanical sensor configuration. The control box receives signals from the metal detector and shows the operator the potential for metal at the location the EMD was sensing.
