摘要/Abstract

摘要： 电子与通信等技术的快速发展使得以此为技术支撑的无人机得到了学术界与工业界的广泛关注。为了适应日益复杂的任务和应用领域,无人机安全数据链路成为推进无人机发展的重要因素。围绕无人机数据链路的安全问题,文中首先讨论了正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)技术的高频谱利用率、抗多径衰落能力等一系列优点,并阐述了其在无人机数据链路中的应用;然后,结合混沌系统具有的长期不可预测特性,提出了一种混沌子载波调制(Chaotic Sub-Carrier Modulation,CSCM)方案,其利用量化分组的混沌序列完成对数据的混沌串并转换及混沌扰乱过程,进而实现无人机数据的加密传输和数据来源可靠性的判断;最后,采用MATLAB对所提方案进行仿真,验证了该方案的可行性和有效性。

Abstract: With the rapid development of electronics and communication technology,UAV (unmanned aerial vehicle) supported by these technologies have attracted the extensive attention of academia and industry.In order to adapt to the increasingly complex tasks and application fields,the UAV secure data link has become an important factor to promote the development of UAV.Focusing on the security issues of UAV data link,this paper discusses a series of advantages of OFDM (orthogonal frequency division multiplexing) technology,such as high spectrum utilization and anti-multipath-fading ability,and explains its application in UAV data link.Combining the long-term unpredictable characteristics of chaotic systems,a CSCM (chaotic sub-carrier modulation) scheme is proposed,which completes the chaotic serial-to-parallel conversion and chaotic disturbance on the data by using the quantized grouped chaotic sequence.This scheme realized the encrypted transmission of UAV data and the judgment on the reliability of the data source.Finally,MATLAB is used to simulate the scheme to verify the feasibility and effectiveness of the proposed scheme.

Key words: Chaotic disturbance, Chaotic serial-to-parallel conversion, Chaotic sub-carrier modulation (CSCM), Orthogonal frequency division multiplexing (OFDM), UAV secure data link
