Abstract:
1. A method for implementing an IED defense system for forcing premature detonation of IEDs having a triggering mechanism responsive to sound energy signals, the IEDs being carried by a moving person or vehicle traveling on a road, the method comprising: radiating in the air from one or more stationary sound energy platforms sound energy signals via speakers that are part of the platforms; selecting the energy signals to be a characteristic noise print to which the IEDs are tuned as the triggering mechanism; defining an IED detonation zone as a predetermined portion of the road along which the moving person or vehicle travels prior to entering a target area where the IED is intended to detonate; locating the one or more stationary sound energy platforms off the road and adjacent to the portion of the road that defines the IED detonation zones; activating the platforms by one or more controllers to radiate the sound energy signals upon the person or vehicle on the road entering the IED detonation zone; the speakers being disposed to transmit the radiated sound energy signals across the road at the IED detonation zone to encounter the person or vehicle, the selected sound energy signals of the characteristic noise print forcing premature detonation of IEDs having a triggering mechanism stimulated to detonate in response to sound energy signals with the selected characteristic noise print within the IED detonation zone.
