ND-BU005 Advanced Passive Anti-Drone System


With exponentially sales of drones around the world, the threat posed by the weaponization of recreational drones already is a reality. The unregulated proliferation of drones in most countries poses a significant danger and threat to their national security.

ND-BU005 Advanced Passive Anti-Drone System is an upgraded version of our passive anti-drone systems with longer detection and jamming range, providing all-around and full-band protection against a variety of drone targets.

The system has been designed and developed against consumer-grade small rotor drones, merging long-range detection, jamming and record tracking functions into one system, for protection of key areas and response to threats from small rotor drones, e.g., illegal drone invasion, terrorist attack, and drug trafficking.

The system mainly consists of Detecting Unit (Full-Band RF Detector) and Jamming Unit (Full-Band Directional Jammer). Detecting Unit can detect and track long-distance drones and lead Jamming Unit to interfere with the remote control circuits and navigation signals of the drones and force the drones to land or return.

Main Features of Detecting Unit

• Full-band detection
• Precise identification and positioning of drone
• Precise positioning of drone controller
• TDOA and AOA composite passive positioning technology
• High maturity design
• All-weather, all-day and omni-directional

Main Features of Jamming Unit

• Full-band jamming, software definable
• Digital jamming source design
• All-in-one design
• High power broadband amplifier design
• Easy installation and wide application
