Abstract

The invention relates to the technical field of unmanned aerial vehicles, and particularly discloses a frequency hopping unmanned aerial vehicle defense method, which comprises the following steps: receiving a radio signal; cracking the radio signal to obtain a cracked signal; transmitting a striking radio signal to the cracking signal; predicting a next frequency hopping frequency band of the radio signal; and transmitting the striking radio signal according to the predicted next frequency hopping frequency band. The invention also discloses a frequency hopping unmanned aerial vehicle defensedevice. According to the frequency hopping unmanned aerial vehicle defense method provided by the invention, the strike radio signal can be transmitted for the predicted frequency hopping frequency band, so that the unmanned aerial vehicle can be effectively defended, the unmanned aerial vehicle cannot be normally controlled, and countering of the unmanned aerial vehicle is realized.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a frequency-hopping unmanned aerial vehicle defense method and a frequency-hopping unmanned aerial vehicle defense device. Background technique [0002] At present, a counter-technology commonly used in the field of UAV defense is software radio protocol cracking technology, which applies advanced radio reverse engineering and security analysis to UAV detection and defense. The specific method is to use software radio technology to crack the radio communication between the drone and the remote control. The cracking content includes frequency, filtering, digital-to-analog conversion, modulation method, and channel coding. In addition to using software radio for cracking at the physical layer, it is also necessary to crack protocols at the media access control, logical link control, network layer, and application layer; decompress some compressed data; decrypt some...
