Precise jamming method for UAV measurement and control signals based on signal reconnaissance and prediction

Abstract

The invention discloses a precise interference method for unmanned aerial vehicle measurement and control signals based on signal reconnaissance and prediction, which is realized by general signal reconnaissance equipment, comprehensive information processing equipment and radio interference equipment; the steps include: general signal reconnaissance equipment acting on it The UAV measurement and control signal in the area is reconnaissance and received; the comprehensive information processing equipment analyzes the received signal, extracts the UAV measurement and control signal parameters, and identifies the UAV measurement and control signal type; predicts the frequency hopping frequency point of the received signal; generates a corresponding The duration and bandwidth of the baseband interference signal, and the baseband interference signal is uploaded to the radio interference device, and the radio interference device processes it and transmits it with radio frequency. Without affecting the normal operation of other legal frequency-using equipment, the present invention realizes precise interference to the UAV measurement and control signal at the minimum cost, and can effectively detect the frequency hopping point in the future in the case of missed detection of frequency hopping Make predictions.

Description

technical field

[0001] The invention belongs to the technical field of electronic information, and in particular relates to a method for precise interference of UAV measurement and control signals based on signal reconnaissance and prediction. Background technique

[0002] The use of radio interference means to interfere with the UAV measurement and control signal entering the no-fly area is an important means of UAV prevention and control. The radio interference methods used at this stage mainly include blocking interference and tracking interference.

[0003] Blocking jamming means that the jammer directly sends broadband jamming signals to block the communication of all devices in the target communication frequency band. However, some UAVs use the ISM frequency band for data communication, and there are a large number of frequency-using devices in this frequency band. High-power blocking interference will affect the normal operation of peripheral frequency equipment at ...
