Description

technical field [0001] The present application relates to the technical field of drones, and in particular to a PCIE card-type drone jamming signal generator, jamming method and related equipment. Background technique [0002] At present, there are more and more types and quantities of drones, and the "black flight" incident has been repeatedly banned, seriously endangering the safety of people's lives and property, and disrupting social order. Countermeasures against drones have become a security measure that must be deployed by relevant government departments and even important private places. At this stage, UAV jamming equipment mainly adopts the method of remote control signal suppression for jamming. By sending high-power fixed-frequency jamming signals or sweeping jamming signals, the drone's remote control signals are suppressed, making it impossible to remotely control the drone with the ground. The drone communicates normally, so as to achieve the purpose of UAV fo...

Problems solved by technology

[0003] The UAV jamming signal generated by the existing UAV jamming equipment has the disadvantages of narrow signal frequency band, slow response speed and single frequency

This kind of jamming signal has a relatively good countermeasure effect against the drones launched early in the market. With the acceleration of the replacement of drones, anti-jamming drones have begun to appear, and the previous jamming signals have been unable to effectively counteract. For making

This anti-jamming UAV uses frequency-hopping remote control signals for communication. This anti-jamming remote control signal has a wide frequency range, up to 100Mhz or 150Mhz, and has the characteristics of fast frequency hopping. The interference signals generated by conventional jamming devices cannot be used in such a way. Complete suppression and fast response in a wide frequency band, so the interference effect is very small
