A system and method for generating counter-electromagnetic waveforms for black-flying drones

Abstract

The present invention provides a generation system and method for anti-electromagnetic waveforms of black flying drones. The system includes a monitoring module, a link feature identification module, and an interference handling module, wherein the monitoring module is used to receive wireless The electromagnetic wave signal between the man-machine and the remote control is input to the link feature identification module; the link feature identification module is used to blindly identify the modulation and frame format of the data link used by the drone from the intercepted electromagnetic wave signal , coding, and signal bandwidth; the interference handling module is used to regenerate the interference waveform according to the identification result, and send it to the air to counter the UAV. Beneficial effects of the present invention: the four basic parameters of the communication link layer used by the UAV can be quickly identified, and based on this, an interference waveform signal with a high signal-to-noise ratio and a high similarity to the real waveform can be reproduced, which can be used to distinguish the real from the real, and improve Interference efficiency, while reducing interference power, prolongs the service life of the device.

Description

technical field [0001] The invention relates to the technical field of UAV countermeasures, in particular to a system and method for generating electromagnetic waveforms against black flying UAV countermeasures. Background technique [0002] In recent years, the UAV industry has continued to grow rapidly. From 2014 to 2018, the global rotor UAV market has grown by about 20% per year. On major e-commerce platforms and shopping malls, people spend at least 2,000 yuan, that is, You can buy a drone that is ready to fly and has functions such as aerial photography. However, when the entry threshold for drones continues to decrease, incidents of unmanned drone flights are on the rise. When drones enter airport airspace, public venues and sensitive areas without permission, there will be risks of endangering public safety and national security. [0003] At present, among the commonly used UAV countermeasures, high-power electromagnetic suppression has low interference efficiency ...

AI Technical Summary

Problems solved by technology

[0003] At present, among the commonly used UAV countermeasures, high-power electromagnetic suppression has low interference efficiency and serious secondary disasters. targeted smart interference

The UAV communication data link waveform is mainly affected by four factors: modulation method, frame format, coding method, and signal bandwidth. In the case of non-cooperation, the above four waveform parameters are difficult to obtain, which creates a problem for the generation of high-fidelity interference waveforms. certain degree of difficulty
