| 摘 要： | 针对一站多目标无人机数据链系统易受干扰的问题，提出一种基于主备链系统抗干扰能力提升的遥控数据信息融合方法，在分析无人机遥控信息业务特点的基础上，对多条链路收到的用户数据进行拆分、融合等处理，设计了多目标无人机数据链的机载遥控信息融合策略。对采用该方法的数据链系统拉距测试验证，结果表明：该方法可在无人机高动态环境下的主备链路状态不稳定时，大幅度减小系统整体丢帧率，提升数据链系统信息传输可靠性。

| Abstract: | To solve the problem which one station controlling multi-UAVs data link system susceptible to interference, a telecontrol data information fusion method for master and slave link system to improve the anti-interface capability of the system is proposed. Based on analyzing the characteristics of the UAV telecontrol information, the user data received from multiple links is split and fused, and the airborne telecontrol information fusion strategy for multi-target UAV data link is designed. The wireless test of the data link system using this method shows that this method can significantly reduce the overall frame loss rate of the system and improve the reliability of data link system information transmission when the master and slave link state is unstable in the high dynamic environment of UAVs. |
