Do plastic rotor blades of drones reflect radar waves?
Yes, plastic rotor blades of drones can reflect radar waves. While plastic itself is not a strong conductor, the rotation of the blades creates a phenomenon known as the micro-Doppler effect. This effect causes frequency modulations in the radar echoes due to the movement of the blades.
In essence, the rotating blades modulate the incident radar waves, making it possible for radar systems to detect and identify drones based on these unique signatures.
