摘　　要：利用Luettgen单次散射信道模型对雾环境下非视距日盲紫外光通信信道传输特性进行了模拟分析。选取波长为260nm的紫外光,分析了雾环境下对于不同的通信距离,该紫外光的路径损耗与能见度的关系。结果表明：在通信距离已知以及系统的发射仰角、接收仰角、发射视场半角和接收视场半角等几何参数已知的情况下,存在一个使得紫外光传输的路径损耗达到最小的能见度;同时,分析并比较了0~2km辐射雾和平流雾传输路径损耗与能见度、通信距离的关系,并得到辐射雾环境更利于紫外光传输。Using Luettgen single scattering channel model,the non-line-of-sight solar blind Ultraviolet transmission characteristics of the communication channel in fog weather were simulated.Selecting the 260 nm UV light,the relationship between the path loss of UV light and visibility for different communication distance in fog weather were simulated.The results show there will be a visibility making the smallest path loss in a situation that the communication distance and the geometerical parameters of launching elevation such as receiving elevation,launching field half elevation and receiving half elevation are known.And also the relations between the transmission path loss and visibility,communication diatance of the radiation fog and advection fog in the range of 0~2km were simulated.And it is obtained that the radiation fog weather is more conducive to UV tranmission.
