What is Anti-Drone?
Anti-drone technology, told as a story about detecting, identifying, and disabling a drone that sneaks over the expo hall.
Is that drone even authorized?Small, fast drones are hard to stop.
Small drones are hard for radar to catch too.Drones are small, fly low, and carry little metal, so ordinary air defenses easily miss them.
Anti-drone is a set of technologies that detects, identifies, and disables an intruding drone.Radar and cameras find the drone; a net or jamming stops it.
Anti-drone work goes in order: detect, then identify, then disable.Skip the identify stage, and you might stop an authorized drone.
Anti-drone systems can wrongly stop an ordinary drone, and jamming can disrupt nearby communications.That's why using anti-drone gear comes with legal limits.
Anti-drone is a set of technologies that detects, identifies, and disables an intruding drone — while managing the risk of false positives and jamming side effects.
An anti-drone system detects drones with radar, electro-optical/infrared (EO/IR) cameras, and RF sensors, identifies friend from intruder using flight patterns and signals, then disables the target via jamming, net capture, or direct takedown. Small, low-altitude, low-RCS (radar cross-section) drones are inherently hard to detect, and jamming can affect nearby communications and navigation equipment, so its use comes with legal and technical constraints.
When grown-ups say it
- Anti-Drone
- The set of technologies that finds and stops an intruding drone. Made up of three stages: detect, identify, disable.
- RF Sensor
- The sensor that catches a drone's control signal. A key tool in the detection stage.
- Jamming
- Cutting the signal between drone and controller. Can affect nearby communications too.
- Low RCS
- Being hard for radar to catch. Why small drones are hard to detect.
- MEC
- Computing nearby a base station for speed. A similar idea helps process detection data fast. → the MEC booth
- Smart City
- Using citywide data to keep the city safe. A booth on city safety services, like early disaster warning. → the Smart City booth
- False Positive
- Mistaking an ordinary drone for an intruder. Easy to get if the identify stage is skipped.
- Aviation Safety Regulation
- The law setting where and how drones may fly. Jamming is limited separately by radio law (in Korea, Radio Waves Act Art. 29).
