激光在云层信道中传输的蒙特卡罗模拟

Monte carlo simulation of light pulse propagation through clouds

针对云层介质对激光传输有较强的吸收和散射作用,严重影响了激光对潜通信系统的应用范围这一问题,采用Monte Carlo法来模拟激光在云层中传输的过程。得出云层光脉冲的时间扩展特性和部分参数的模拟结果,为通信系统进行后期的分析和设计提供了一定的理论和实用价值。

The transmission of laser is affected by clouds because of its absorption and scattering characteristics, so the application scope of submarine laser communication is restricted. The process of laser transferring through clouds is simulated by means of Monte Carlo. The time spreading caused by clouds for laser pulse are obtained and parameters such as thickness of the clouds medium and the extinction coefficients are varied to simulate different cloud properties,which can be provided as a great theoretical and practical reference for study and design of communication system.
