drone uav scrambler is one of the most practical weapons for the unmanned aerial vehicle flying phenomenon. It scramble the WiFi 2.4Ghz and 5.8Ghz frequency bands used by drone flight control and forces the unmanned by cutting off the signal. Landing, or returning. Relative to signal interference, this gentle drone jammers anti-UAV method, the violent anti-UAV method is mostly used for military purposes, and its characteristics are one word: violence! The purpose is also very straightforward: the grass is removed from the roots, leaving no room for it.
In August last year, researchers from the Korea Advanced Science and Technology Research Institute (KAIST) published a report saying that a new type of "sound wave interference anti-UAV system" was developed, which is not the same as the signal interference of drones. The way is to use sound waves to interfere with the hardware of the drone and disable it.
Inside the drone there is an important component, the gyroscope, which provides the drone with information such as tilt, rotation and direction of the body to maintain balance. This study proves that when the acoustic frequency is consistent with the natural frequency of the drone gyroscope, resonance occurs, making the gyroscope unable to work properly, causing the drone to fall. Although the method of interfering with hardware is more violent and more direct, the relative signal interference is insufficient. The aiming and tracking of acoustic interference is not as stable as GPS interference, and the cost is expensive. It is not suitable for use in the public anti-UAV system.
