Nuetralize Enemy Drones

Description:

TECHNOLOGY AREA(S): Electronics 

OBJECTIVE: Develop new, innovative sensors and systems architecture to sense enemy drones at distance and neutralize drone threats before they reach their intended target. 

DESCRIPTION: The asymmetric threat of IEDs and other hazards must be addressed by a new generation of innovative technology including robotics, drones and novel sensors for situation awareness. Further work is needed to advance air and ground teaming capabilities that allow drones and robots to work together to find hazards and map out large areas. One of the most worrisome threats is the use of drones as weapons by insurgents. The threat of drone strikes is on the rise throughout the world. Stephen Townsend, the commander of Operation Inherent Resolve, prioritizes drone weaponization as the number one threat facing soldiers in the effort to combat ISIS. Insurgents can purchase a drone for anywhere from $200 to $20,000 dollars and then use that device to cause devastating damage by attaching explosives and using multiple drones in simultaneous, coordinated attacks. To address this threat, there is a pressing need to develop new, innovative sensors to sense drones at distance and neutralize drone threats before they reach their intended target. Numerous sensors may be considered, but must meet the following specifications: 1) low cost; 2) capable of being made rugged for use on drones and robots; 3) small size and weight to support deployment on small drones; 4) ability to see out at least 200 meters; 5) ability to see through obscurants such as dust, rain, fog, snow and vegetation. For example, Ultra Wide Band (UWB) digital radar sensors can be used to provide a unique means to track UAS threats at large distances. UWB radar transmits high bandwidth (narrow) Gaussian pulses that can be very low power. When the transmitted pulses that enable the monostatic operation of one radar are received as pulse responses by a second radar a bi-static radar link is established; when the pulse responses are received by several radios a multi-static radar is formed. A network of low cost UWB radars can be used to form a C-UAS perimeter around an area in order to prevent swarming enemy UAS platforms from penetrating and operating in the airspace above the protected area. Another mode of operation under consideration is the use of UWB radar on drones and robots as a means to track and intercept drones in real-time. 

PHASE I: The proposed work during PHASE I is expected to include development of a system architecture for using some combination of sensors, drones, ground vehicles and unattended ground sensors to create C-UAS capabilities. During PHASE I proposers may consider demonstration of the core sensor capabilities necessary to sense and track UAS systems and possible simulation of the proposed functional system. 

PHASE II: Phase II will involve prototyping of the system and may include demonstration of the sensors on drones and ground vehicles. 

PHASE III: Phase III will involve collaboration with PM Counter-Explosive Hazards in order to develop a fieldable C-UAS solution to the threat of airborne explosive threats.
