针对大气中紫外光散射通信的特点,用Monte Carlo方法对紫外光非直视(NLOS)通信三种工作方式的覆盖范围进行分析,建立了基于Monte Carlo方法的NLOS紫外光传输模型.利用Monte Carlo模拟方法对三种NLOS散射方式的单次和多次散射路径损耗及覆盖范围进行模拟研究,结果表明,多次散射和单次散射的路径损耗基本一致,NLOS(a)类全向发送全向接收通信方式覆盖范围最小但全方位性好,NLOS(b)类定向发送全向接收通信方式的覆盖范围较大但有一定方向性,NLOS(c)类定向发送定向接收通信方式的覆盖范围最大但有很强的方向性.
According to the characteristic of ultraviolet scattering communication in the atmosphere, Monte Carlo method was used to analyze the coverage of three working modes of NLOS communication, and the NLOS ultraviolet transmission model based on Monte Carlo method was established.Using Monte Carlo Simulation results show that the path loss of multiple scattering and single scattering are basically the same. The NLOS (a) class omnidirectional transmission omni-directional The coverage area of the receiving communication method is the smallest but omnidirectional, the coverage of the NLOS (b) directional all-directional receiving and transmitting omni-directional communication is large but directional, and the coverage of the directional receiving and receiving communication of the NLOS (c) But there is a strong direction.
