无人机数据链系统是无人机系统的核心组成部分,为了验证其在超宽带电磁脉冲(UWB)场环境下的安全性及可靠性,在开阔场搭建了UWB电磁脉冲辐射系统。利用UWB电磁脉冲辐射系统对无人机数据链系统进行辐照效应实验。实验结果表明:单次触发的UWB辐射场不会对无人机数据链系统产生干扰;在连续触发条件下,无人机数据链系统会出现失锁现象,此效应与触发频率和辐照场强有关,且辐照场强与触发频率成反比关系。通过分析得知,无人机数据链路系统受UWB电磁脉冲辐射场干扰的能量耦合通道为“后门”耦合。
UAV data link system is the core part of the UAV system. In order to verify the safety and reliability of the UAVB system, an UWB electromagnetic pulse radiation system is set up in the open field. Radiation effect experiment of UAV data link system by UWB electromagnetic pulse radiation system. The experimental results show that the single-triggered UWB radiation field will not interfere with the UAV data link system. Under the continuous triggering condition, the UAV lock-out phenomenon will occur. This effect is related to the trigger frequency and the radiation field Strongly related, and the radiation field strength and the trigger frequency is inversely proportional relationship. Through the analysis, we can see that the energy coupling channel of the UAV electromagnetic radiation field is the “backdoor” coupling of UAV data link system.
