Unmanned aerial vehicle-mounted high sensitivity RF receiver to detect improvised explosive devices

摘要

Improvised Explosive Devices (IEDs) are increasing in complexity and lethality. A RE system is needed to detect the presence of RF IEDs. This thesis describes the evolution of a proven ground-based RF detection system. It is designed to collect unintended radio frequency emissions from the IED's RF triggers and receivers. Modification of the ground-based version allowed placing this RF system into an airborne platform. The detection range and corresponding time to react to a possible threat is dramatically improved. Increased time provides greater protection for the front line troops that are primary targets of RF IEDs, hence reducing the casualties of U.S. troops. Field testing and technical feasibility demonstrations are conducted using a NPS-owned TERN UAV at McMillan Airfield located at Camp Roberts, CA. The research conducted for this thesis primarily deals with the implementation and testing of this RF system onto UAVs. Several additional benefits make this RF system useable over a wide range of applications.
