Method of Locating Unexploded Ordnance

The Unexploded Ordnance Asset RFID System (UARS) is an active low frequency RFID tracking system designed for locating unexploded ordinance (UXO) on the battlefield.  The system is a passive thin collar RFID tag that is placed onto the munition during manufacture and becomes activated after delivery on target.  Once activated, the RFID tag enters a passive listening mode, waiting for a specific excitation signal before responding.  This design allows for unprecedented system shelf life, a long active lifetime, and superior ranges of operation for detecting both above ground and underground UXO.   The user friendly, vehicle mounted reader design allows for accurate detection and location of the tags from extended distances.   The secure RFID tag contains information critical to Explosive Ordnance Disposal (EOD) teams directly on the tag, with the full history of the munition stored on a centralized database.   BENEFIT: The UARS is poised for immediate impact reducing civilian deaths from UXO and reducing the quantity of UXO that is reused as Improvised Explosive Devices against US Forces.    By small adjustments to the packaging geometry, the underlying technology can be readily applied to the tracking of additional munition types such as other Mk80 series bombs, cluster munitions, missiles, and unguided rockets.
