摘要
本文分析了激光传输过程中大气这一传输介质对其的影响,由大气的成分出发,采用辐射传输理论描述了大气介质的吸收和散射特性,着重分析了其中对辐射影响最大的两种因素,即大气消光和大气湍流。并建立了大气传输系统的传递函数模型。最后通过LOWTRAN模拟软件包对本文所得的模型进行评估。
The attenuation of laser through the atmosphere is analyzed. Atmosphere absorption and scattering are described by radiation propagation theory. We analyze air extinction and air on flow on emphasis which are the most important factors to the absorption of radiation propagation. The atmospheric transfer function model is constructed. At last, we evaluate this function model with the help of LOWTRAN software.
