Cliff Johnson, a Raytheon director for business development in tactical radars, has said the company's Ku-band Radio Frequency System and Sentinel radar technology work to detect small drones.
KuRFS was originally built to help the U.S. Army counter rockets, artillery and mortar fires during military operations in Afghanistan and Iraq, while Sentinel was designed to alert air defense weapons of aircraft or missile threats, Raytheon said Wednesday.
“Both KuRFS and Sentinel are eyes in the sky,” Johnson noted.
“With the smaller drones, operators have less to detect due to smaller wing, motor and engine sizes, and they fly slower that many radars are tuned for."
The company also developed a high-energy laser that can operate with a radar to recognize incoming drones.
