British Companies Develop Anti-UAV Defence System that Uses Radio Beams

Sophisticated, easy to fly drones are everywhere these days and like most new technologies, they have the potential for mischievous or malicious applications as well as positive ones. It follows that there’s an increasing demand for improved surveillance and countermeasures specifically tailored for this type of aircraft. Billed as the world’s first fully integrated system designed to detect, track and disrupt small and large drones, the Anti-UAV Defence System (AUDS) from Blighter Surveillance Systems uses radio beams to freeze drones in midair by interfering with their control channels.

The AUDS was developed by a partnership of three British companies: Blighter Surveillance Systems, Chess Dynamics, and Enterprise Control Systems. The system is of a modular design for fixed or mobile platforms with each individual unit weighing about 25 kg (55 lb). These units consist of a A400 Series Ku band electronic scanning air security radar, a stabilized x30 electro-optic director with infrared, thermal, and daylight cameras, and a directional radio frequency (RF) inhibitor. The AUDS uses the radar and optical trackers connected to proprietary software to detect, track, and identify the drone at distances of up to 8 km (5 mi).Read more
