某型无人机数据链连续波电磁环境效应试验研究

Test Study of Continuous Wave Electromagnetic Environment Effect for a Certain Type of UAV Data Link

为客观考核评价无人机数据链对不同频率连续波的电磁敏感程度,研究连续波干扰导致数据链的失锁效应以及失锁机理。本文先后开展某型无人机数据链连续波干扰辐照和注入试验,结果表明,对于同频干扰,当连续波干扰在机载天线附近产生的辐射场场强不小于0.0084 V/m时,即可导致数据链失锁;注入法与辐照法的试验结果具有较好的一致性,该研究成果为无人机数据链干扰预测打下良好的基础。

In order to evaluate the electromagnetic sensitivity of the UAV data link to different frequency continuous waves, the unlocked the data link and the mechanism of unlocked are studied. In this paper, the continuous wave interference irradiation and injection test of UAV data link are carried out respectly. The results show that for the same frequency interference, when the continuous wave interference is not less than 0.0084 V/m in the radiation field near the airborne antenna, the data link communication can be interrupt. The test results of the injection method and irradiation method have good consistency. The results of the study lay good foundation for the interference prediction of the UAV data link.
