The invention relates to the technical field of wireless and mobile communication and covert communication, and discloses an unmanned aerial vehicle assisted covert communication trajectory optimization method, which constructs an unmanned aerial vehicle assisted covert communication trajectory optimization system, and comprises an unmanned aerial vehicle sending end, a plurality of legal ground user receiving ends and a monitor Warden. The system further comprises two channel links: a covert communication link from the unmanned aerial vehicle sending end to each ground user and an eavesdropping link from the unmanned aerial vehicle sending end to a monitor Warden. According to the method, the unmanned aerial vehicle is used for assisting covert communication, the track of the unmanned aerial vehicle is optimized, the problems that a traditional communication method is narrow in communication range, a base station is fixed and inflexible, and signals are blocked are effectively solved, the stability and coverage of covert communication are improved, variables are successively optimized by adopting an approximate convex optimization method, and the communication efficiency is improved. And the optimal variable is taken.
