Unmanned aerial vehicle frequency hopping communication method and device, computer equipment and storage medium

Abstract

The invention relates to the technical field of unmanned aerial vehicle communication, and discloses an unmanned aerial vehicle frequency hopping communication method and device, computer equipment and a storage medium. Through the creation of the invention, a frequency hopping communication scheme for dynamically generating a consensus frequency hopping sequence based on a channel estimation technology is provided, that is, on the premise of not depending on a special frequency hopping system, a frequency hopping sequence which does not need to be agreed in advance can be dynamically generated between a common ground station (or an unmanned aerial vehicle) and an unmanned aerial vehicle; therefore, dynamic networking requirements between different unmanned aerial vehicles and a ground station can be met, both communication parties of the unmanned aerial vehicle can continuously switch frequency points according to time slices based on the generated frequency hopping sequence to communicate, and the communication confidentiality of the unmanned aerial vehicle based on frequency hopping communication in a frequency hopping sequence dynamic generation mode can be greatly improved. The method prevents an eavesdropper from stealing information, gets rid of hardware and cost limitations existing in a military frequency hopping mode, and can be suitable for special application scenes.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle communication, and in particular relates to an unmanned aerial vehicle frequency hopping communication method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of drone technology, more and more tasks can be performed by drones. However, at present, the radio signals between UAVs or between UAVs and ground stations are generally transmitted by fixed-frequency communication, and there is a hidden danger of eavesdropping. Although some UAVs have upper-level security and confidentiality agreements for data Encryption, but in view of the broadcast physical characteristics of radio signals, the risk of being intercepted for brute force cracking is high, especially when performing some major tasks or transmitting sensitive information, which will make communication security unreliable. [0003] Although the above problems can be sol...

Problems solved by technology

[0004] In order to solve the existing unmanned aerial vehicle communication technology and the limitations of military frequency hopping mode, the purpose of this invention is to provide a A novel UAV frequency hopping communication method, device, computer equipment and storage medium, which can be independent of a dedicated frequency hopping system, and can be dynamically generated between common ground stations (or UAVs) and UAVs without prior The agreed frequency hopping sequence can further meet the dynamic networking requirements between different UAVs and ground stations. It can not only enable the two sides of the UAV communication to communicate by continuously switching frequency points according to the time slice based on the generated frequency hopping sequence, but also UAVs based on the dynamic generation of frequency hopping sequences can greatly increase the confidentiality of their communications, prevent eavesdroppers from stealing information, and get rid of the hardware and cost limitations of military frequency hopping methods, which can be applied in special application scenarios
