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.

    本发明涉及无线及移动通信、隐蔽通信技术领域,且公开了一种无人机辅助下隐蔽通信的轨迹优化方法,构建无人机辅助下隐蔽通信的轨迹优化系统,包括一个无人机发送端,多个合法地面用户接收端、一个监听者Warden;还包括两条信道链路:从无人机发送端到各地面用户的隐蔽通信链路以及从无人机发送端到监听者Warden的窃听链路。该方法通过利用无人机辅助隐蔽通信,并对其轨迹进行优化,有效地解决了传统的通信方法面临的通信范围窄,基站固定不灵活,信号阻断等问题,提高了隐蔽通信的稳定性和覆盖范围,并且采用近似凸优化的方法,对变量进行了逐次优化,直到最优变量被采取。
