The rapid proliferation of drone technology has positively transformed several industries driving advancements in agriculture, delivery services, filmmaking, and surveillance. However, this technological leap also introduced significant challenges, particularly the unauthorised use of drones in sensitive areas. Nefarious drone activities pose a threat to national security, public safety, and the effective operations of emergency services.
A striking example occurred when a Bombardier Canadair CL-415 firefighting aircraft was grounded after being struck by a drone. This incident severely impacted firefighting efforts in Los Angeles during active wildfires, as was widely reported by media outlets. Understanding these threats and the building blocks available to construct countermeasures, is crucial for creating a safer environment.
Evolving Threats to Security
Military and law enforcement agencies face increasingly complex threats, including the weaponisation of drones, their use in espionage, and coordinated drone attacks - particularly in conflict zones. High value assets, such as naval vessels, are now also at risk when operating near shorelines or docked in a harbour.
The DNA of a Counter-UAS System
To combat these challenges, Counter-UAS (C-UAS) systems have become indispensable for monitoring, tracking and neutralising drone threats. These systems integrate various technologies to detect, track, and, if necessary, disable drones operating in restricted zones.
A Counter-UAS System can incorporate multiple layers of functionality, depending on the operational use case and threat profile being targeted. Key capabilities include:
· Detection: Utilising radio frequency (RF) sensors, and electro-optical systems to identify drones.
- Tracking: Employing radar and or RF direction-finding technologies to locate unauthorised drones. Typically, multiple tracking stations are required for accurate geolocation, although some advanced technologies enable geolocation with a single tracking station
- Neutralisation: Implementing RF jamming, directed energy weapons, kinetic countermeasures or the physical capturing of the target to disable or limit activity.
