摘要
某型无人机传统电磁辐照试验以"失锁"效应作为数据链受干扰程度评价标准,此时地面控制站与无人机通信受到严重干扰甚至出现中断现象.为了细化无人机受单向连续波辐照干扰程度,量化干扰等级,在无人机连续波常见辐照效应基础上,引入数字光纤通信领域普遍推行的误码检测手段,建立无人机连续波辐照误码检测系统.通过建立误码率与飞机工作异常现象之间的关系,评估无人机战场潜在威胁,并进行可行性验证,得到误码率大于1×10-5对应数据链失锁.
The effect of unlock is deemed as the criteria to evaluate the degree of interference in traditional electromagnetic radiation experiment of UAV .When it happens,datalink communication is disturbed by the severity of the interference,and even blocked.In order to refine the extent of continuous wave radiation interference with UAV and quantify the level of interference,the paper introduces bit error rate （BER）which is widely adopted in digital optical communication to establish a system of error detection based on common continuous wave radiation effects of UAV .Through the establishment of a relationship between BER and aircraft anomalies,the system can assess potential threats to UAV on the battlefield,and finally the feasibility is verified.It is approved that the data link would unlock when the error rate is greater than 1×10 -5 .
