摘　　要：目前空-地单光子通信系统的设计大都基于分系统进行性能分析,很难给出系统级的性能参数,为系统设计优化提供可信的支持.为了综合评价空-地单光子通信的系统性能,采用全链路系统仿真的方法,基于离散事件仿真器构建空-地单光子通信仿真的全链路系统,通过蒙特卡洛方法仿真模拟捕获、瞄准、跟踪过程和单光子通信过程,有效模拟各子系统间的耦合关系,对空-地单光子通信系统的关键性能参数做出综合、准确的评价,为系统设计和优化提供依据.The existing designs of space-to-ground single-photon communication have the defect that the system-level parameters are difficult to be given,due to the adoption of the analysis based on subsystems.For the purpose of combining all subsystems and key system-level parameters＇ influence, full-link simulation method is introduced.A space-to-ground optical communication full-link simulation system based on OMNeT＋＋ is constructed to perform the APT（Aiming,Pointing,Tracking） and single-photon communication experimentation by Monte-Carlo method.The simulation system has the abilities of simulating correlations between subsystems,reflecting the key parameters＇ influence on the whole system,and estimating the performance of a true system due to its full-link character.The simulation system is significant to design and optimize true space-to-ground optical communication systems.
