NovoQuad ND-BU002 High-End Anti-Drone System

Description

System Overview

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. Military bases, public buildings, critical infrastructures, power stations, offshore oil & gas platforms, sport stadiums, mass gathering events, and political leaders are all vulnerable to drone attacks. Terrorists have already used drones to launch attacks against civilian and military targets around the world. The illegal drone threat must be addressed with appropriate technology immediately.
ND-BU002 High-End Anti-Drone System is designed 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, Jamming Unit and Camera Unit.
The Detecting Unit, which employs the advanced 3D active phased-array radar, is specifically designed for detecting and tracking long-distance drones. It can detect the drone position not only in horizontal angle but also in vertical angle.
Guided by the accurate drone position information, the Jamming Unit with tall antenna and low power jammer will interfere with the remote control signals and navigation signals of the drone and force it to land or return.
The Camera Unit can efficiently record the tracks of the detected drone for further close inspection, and also assist the Detecting Unit for more accurate monitoring.

Typical Targets

Detecting Unit Description

The Detecting Unit which employs the advanced 3D active phased-array radar is the key to the whole ND-BU002 System.
The phased-array radar is a category of radar sensors that are capable of monitoring hostile activities on the surroundings of critical infrastructures
and objects；however, such kind of radar can not detect drones directly.
As drone RCS* is quite small, usually around 0.01m2 (the size of DJI Phantom 4 Micro Drone RCS is 0.01 m2), it is especially difficult to detect drones. (*RCS: Radar cross-section (RCS) is a measure of how detectable an object is with radar. A larger RCS indicates that an object is more easily detected. An object reflects a limited amount of radar energy back to the source.)
The 3D active phased-array radar we employed with the unique algorithm focused on small RCS flying object, is able to rapidly report the speed, distance, direction, altitude and other information of the invading drone.
By adopting the Detecting Unit, much more accurate tracking data would be obtained through electronic scanning. Within the same detecting range, both the power consumption and the size of the ND-BU002 System are significantly reduced.

Advanced 3D active phased-array radar

Jamming Unit Description

The Jamming Unit could block radio frequencies used by drones and the frequency bands of GPS L1 system in case that drones fly in auto-pilot mode.

Depending on the application, protection level and geographical location, the Jamming Unit may be adapted in terms of frequency band coverage and output power.

The detected drone may be tracked by radar itself. Combined with the directional antenna mounted on a pan-tilt platform, the tracking allows positioning the jammer antenna directly onto the detected drone, so as to transmit the jamming signal precisely and focused toward the target .

Guided by the target information (e.g., speed, distance, direction and pitching) provided by the Detecting Unit, the Jamming Unit is able to rapidly adjust the antennas to interfere with the invading
drone and force it to land or return.

Main Features of Jamming Unit

Precise jamming without violence
9 frequency bands of jamming signals (frequency bands and output power can be customized) Support automatic/manual mode switching
Remote control frequency jamming: coverage of all available civil drones
Directional high-gain antennas mounted on Pan-Tilt platform can effectively track drone and transmit jamming signal in the direction of the drone
