Sound wave based anti-UAV system

Abstract

The invention discloses a sound wave based anti-UAV (unmanned aerial vehicle) system which is characterized in that position information of an attack UAV is found and collimation position deviation is calculated in real time through a positioning tracking device, and the position information and the collimation position deviation are transmitted to a control and display device in real time; the control and display device transmits the collimation position deviation to a servo module of a sound wave attack device in real time so as to drive the sound wave attack device to aim at the target UAV dynamically in real time; when the target UAV enters an early warning range, the control and display device displays a motion trail of the target UAV in real time; and when the target UAV enters an attack range, the control and display device sends an attack instruction to the sound wave attack device, the sound wave attack device then transmits a sound wave attack signal to the target UAV, and the UAV generates resonance and thus falls down. Through a method of toughly destroying the UAV on general and special occasions by emitting sound waves capable of resonating with a component of the UAV, the purpose that the UAV can be effectively struck in general cases and can also be struck back in particular cases is achieved.

Description

technical field [0001] The invention belongs to the technical field of anti-drone, in particular to an anti-drone system based on sound waves. Background technique [0002] In recent years, the civilian UAV market has become increasingly popular. UAVs have been widely used in personal aerial photography, film and television shooting, power inspection, forest fire prevention, police evidence collection, map surveying and mapping, etc. With continuous breakthroughs in technology, drones have become a comprehensive platform with powerful performance and comprehensive functions, which can follow autonomously, fly on a trajectory, and surround at fixed points. [0003] Anti-UAV technology refers to methods and systems for reconnaissance and destruction of illegally flying UAVs. [0004] At present, there are two main methods of countering drones. One is the method of GPS deception. For example, the application publication number is: CN105842717A, and the patent application titl...

AI Technical Summary

Problems solved by technology

[0007] The above anti-drone methods mainly adopt strong interference and physical capture in technology, the process is complicated, the operation is difficult, the technology is difficult, and there are certain conditions and restrictions

With the development of technology, some drones have begun to consider navigation that does not depend on GPS, and the above-mentioned technology has no effect; adopting the method of casting a net to capture is not only easy to be found by the other party, but also has a low capture rate
