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.
