FREMONT, CA: Anti-drone systems are developed to identify and neutralise drones, or unmanned aerial vehicles (UAVs). As the popularity of drones is only increasing, the probability of their misuse is also at par, resulting in the creation of anti-drone systems. These systems employ detection sensors and countermeasures to ensure the prevention of impermissible use of drones in sensitive locations or events.

Counter unmanned aircraft systems (CUAS) pertains to technologies and methodologies used in detecting, tracking, and neutralising drones, or UAVs, that pose a threat. CUAS is primarily utilised in law enforcement, military, and other security applications to defend against unauthorised drones being utilised for malicious purposes. Typically, CUAs systems consist of a combination of communication systems, sensors, and countermeasures to detect and counter potential UAV threats. CUAS uses multiple technologies to facilitate its functions.
Jamming Systems: It uses radio frequency (RF) jamming to interfere with a drone's control signals or GPS navigation, which constrains its controls and forces the drone to land.
Radar and Other Detection Systems: These systems utilise RF, acoustic, radar, and visual sensors to detect and track drones.
Drone-hunting: Some countries train and use birds, such as eagles or falcons, to intercept and capture suspicious drones mid-air.
Netting Systems: Some systems are built to use nets to capture drones mid-air and descend them safely.
Laser System: These systems target and disable drones’ communication systems, therefore, damaging them.
CUAS is vital to prevent the malicious use of drones, as the popularity and availability of drones are on the rise.
The Working of CUAS
CUAS works in specific steps:
Detection: CUAS first recognises drones in airspace by using RF, radar, acoustic, and visual sensors. Different types of sensors are used to detect drones at different ranges and altitudes.
Identification: After the detection of the drone, the type of drone is identified, and is classified as to whether it poses a threat or not. This can be identified by analysing the drone’s communication signals, either visually or electronically.
Tracking: After identification, the drone’s location and movement are tracked using the CUAS system. This is done by using sensors such as GPS, camera, or radar.
Threat Assessment: By observing the drone’s behaviour, and other factors, it is analysed to determine if the drone poses a potential threat.
Neutralisation: In scenarios where the drone does pose a threat, the CUAS systems make use of countermeasures to neutralise it. This may include jamming the drone’s control signal or GPS navigation, using nets to capture the drone, or disrupting its communication systems.
Post-op Analysis: Next, the CUAS system analyses the data in the drone to better its performance in future operations
CUAS can be operated by itself or manually, based on the system used and its requirements. Therefore, CUAS is becoming increasingly important to limit the misuse of drones for malicious practices.
