无人机数据链是无人机的重要组成部分，是飞行器与地面系统联系的纽带。首先按照飞行高度和重量对无人机进行了分类，在此基础上概述了外军无人机数据链的发展现状；然后介绍了几种典型无人机数据链如数字数据链( DDL)、战术通用数据链( TCDL)和Quint网络技术( QNT)数据链的发展和性能，并分析和展望了无人机数据链通用化、安全化、网络化等发展趋势；最后总结了外军无人机数据链发展的经验，希望为从事无人机和数据链研究的工程技术人员提供参考。%The data link is an important component of unmanned aerial vehicle(UAV),connecting UAV to ground system. First,the UAVs are classified according to fligh height and payload. Based on that,the cur-rent status of foreign military UAV data link is summarized. Secondly,some typical UAV data links such as Digital Data Link(DDL),Tactical Common Data Link(TCDL),and Quint Network Technology(QNT) data link are introduced and the trends of UAV data link are analyzed. Finally,the development experience of for-eign military data link is summarized. The related information provides reference for those engaged in UAV and data link.
