| 摘 要： | 针对紫外光大气传输理论和非直视单散射模型，分析了大气信道对紫外光通信的影响，并在不同参数条件下，对大气信道所产生的时间延迟进行了定量仿真。仿真结果表明：时，可延迟／疃通信距离的增加而迅速增大，通信距离增加1km，时间延迟增加约2倍；时间延迟随发射和接收仰角的增加而增加，且发射仰角对时间延迟的影响大于接收仰角；时问延迟压壅发射束散角和接收视场角的增咖而减小。因此，为减小通信系统的时间延迟，在紫外光通信系统设计时，应尽量减小系统的发射仰角和接收仰角，增加系统的发射束散角和接收视场角。

| Abstract: | UV atmospheric transmission theory and the Non-Line of Sight single scattering channel model were introduced.According to the model,the transmission loss caused by atmospheric channel under different structure design was qualitatively analyzed,and the attenuation under different parameters was quantitatively simulated.Experimental results show that delay time increase with increasing transmission distance,launching elevation and receiving elevation,and influence degree of launching elevation is more serious... |
