无人机(unmanned aerial vehicle,UAV)数据链抗干扰功能的增强是UAV实现战时信息资源共享的核心目标。在分析现有无人机数据链研究现状的基础上,重点综述了UAV数据链抗干扰功能的两类方案:一是在单链路方面,对现有UAV数据链的信道编/解码技术作了比较,并对其他抗干扰现状进行了研究;二是多链路方面,对多链路组网的抗干扰技术进行了深入分析,综述了协同通信在多链路UAV数据链中的应用。抗干扰关键技术的综述为下一代UAV数据链的研发提供一定的理论与技术基础。
The key goal of sharing martial information resources is to enhance the anti-jamming function of UAV data link.Based on analyzing actuality of UAV data link,overviewed two issues for anti-jamming of UAV data link.Firstly,made a comparison of methods for channel code of current UAV data link and performed an overview of researches on anti-jamming techniques.Secondly,analyzed a review of anti-jamming techniques using in multi-link network.Lastly,presented an overview of application research on cooperative communication in the multi-link network of the UAV data link.Provided some kinds of foundation for next generation UAV data link through the overview of research on theoretic and techniques.
