Drone mitigation methods and apparatus
View Patent ↗Systems and methods for drone mitigation, or the deterrence of aerial drones from flying in an given area, are described. The systems and methods take advantage of the fact that destabilization of a drone can be accomplished by externally changing the performance of one or more of its propeller driven systems. In doing so, the drone is incapable of maintaining stability in flight, thereby causing the remote controlled pilot to force a retreat, or risk and result in a crash of the drone. Embodiments utilizing sonic energy and liquids are described.
1. A sound-based drone mitigation system comprising:
an array of sonic transducers operative to produce sonic energy sufficient to cause resonances on the blades of a rotor; and
a control and power unit operative to supply energy to the sonic transducers and direct the array in a desired direction.
2. The system of claim 1 , wherein the sonic energy is ultrasonic energy.
3. The system of claim 1 , wherein the sonic energy is infrasonic energy.
4. The system of claim 1 , further comprising a tracking and detection unit operative to detect and track a drone, wherein the control and power unit is operative to receive signals from the tracking and detection unit and direct the array of sonic transducers in the direction of the drone during flight.
5. The system of claim 4 , wherein the tracking and detection unit is RF-based.
6. The system of claim 4 , wherein the tracking and detection unit is optical-based.
7. The system of claim 4 , wherein the tracking and detection unit is acoustic-based.
