Passive drone detection involves using methods to detect the drone and/or its controller without emitting any signals.
Examples of passive drone detection methods:
- RF drone detection systems receive and analyze the communication signals between the drone and its controller.
- Acoustic sensors receive and analyze the sounds emitted by drone motors and propellers.
- Cameras detect drones by capturing images or videos of the surrounding area. These can be standard optical cameras or more advanced systems, such as infrared cameras for night vision.
- Passive radar systems detect and analyze reflected signals from other electromagnetic sources. They provide information on the location and movement of objects without emitting their own signals.
