Anti drone system uses radio frequency famming to jam drones over 1.2 miles away

Blighter AUDS (Anti-UAV Defence System) is a counter drone system that is designed to disrupt and neutralise unmanned aerial vehicles (UAVs), remotely piloted aircraft systems (RPAS) or unmanned aircraft systems (UAS) engaged in hostile airborne surveillance and potentially malicious activity. The Blighter AUDS system combines electronic-scanning radar target detection, electro-optical (EO) tracking/classification and directional RF inhibition capability.

Blighter AUDS is a smart-sensor and effector package capable of remotely detecting small UAVs and then tracking and classifying them before providing the option to disrupt their activity. The system may be used in remote or urban areas to prevent UAVs being used for terrorist attacks, espionage or other malicious activities against sites with critical infrastructure.

The AUDS Team brings together three leading British companies, each with the unique capabilities required to create an effective counter UAV system. Blighter’s A400 series air security radars are able to DETECT small UAVs in all weather conditions, 24 hours a day. The Chess Dynamics Hawkeye EO/IR camera system, with state-of-the-art video tracking technology, is able to TRACK the UAV and, combined with radar target information, classify the target. The operator is then able to make a timely and informed decision to use the Enterprise Control Systems (‘ECS’), smart RF inhibitor to selectively interfere with the C2 channels on the UAV allowing the system to DISRUPT the UAV’s mission.

The latest version of the system uses a quad-band radio frequency (RF) inhibitor/jammer that can disrupt all commercial drone licensed telemetry bands, and is effective against micro UAVs at up to 2 km (1.2 mi) and mini UAVs at longer ranges. Radio beams to freeze drones in midair by interfering with their control channels.

The AUDS made its public debut in May and has undergone testing in Europe and North America in different terrains ranging from open country to urban settings. A production version was showcased at the DSEI Show in London last month and is available from Blighter or Lighteye Systems in the US for £800,000 (US$1.2 million).
