Counter Drone measures (also referred to as Counter UAV or Counter UAS) are countermeasures to stop rogue or unwanted drones in their tracks. These measures can be split into three broad categories of actions to mitigate a drone threat:
- Drone Detection i.e. the use of acoustic, optical or other sensors to detect an incoming drone threat, track its heading and (if possible) identify its origin and aims.
- Non-Interactive Responses i.e. the activation of defense mechanisms which do not in any way interact with the rogue drone. These are measures like evacuation, pulling down blinds, turning of Wi-Fi, and other means of circumventing an intrusive device.
- Drone Interdiction i.e. the deployment of either a kinetic or non-kinetic counter-drone interdiction system to directly mitigate the drone threat.
