Abstract

The invention provides a data link anti-suppression and anti-deception-jamming method for an unmanned aerial vehicle. The method comprises two steps of data transmission and data receiving. In data transmission, multi-system frequency spreading technology and hopping-spreading-separated interweaving technology are combined for improving anti-compression-jamming capability of the system and reducing bit error rate. A frequency hopping sequence is generated by means of a secret key flow generating algorithm, thereby greatly improving safety of a frequency hopping sequence in a traditional data link system. In data receiving, information integrity verification is performed through an authentication code so that a data link system can effectively resist deception jamming from an enemy side to the unmanned aerial vehicle, thereby improving jamming resistance.

Description

technical field [0001] The invention belongs to the technical field of communication engineering, and in particular relates to an anti-suppression and anti-spoofing interference method for an unmanned aerial vehicle data link. Background technique [0002] UAVs are playing an increasingly important role in modern warfare. Compared with manned aircraft, UAVs can do large overload maneuvers, change their flight attitude without restriction, have better stealth, and penetrate dangerously behind enemy lines. There is no need to worry about casualties in the zone. Compared with reconnaissance satellites, UAVs have a low flying altitude, controllable range of activities, easy deployment, and low cost. UAVs have advantages that cannot be replaced by other platforms. At present, all countries are actively developing and deploying new types of UAVs. The performance of UAV data link directly determines the safety and flight efficiency of UAV missions, and is the key to UAV technolog...
