Simulation and Optimization Design of the Layout between Laser Communication System and Lunar Observing Ground System

针对地基观月系统与激光通讯系统的布局优化,避免激光散射对地基观月系统探测器造成过高辐射干扰的问题。文中采用STK软件进行仿真,证明了地基观月系统探测区和激光通讯区在空间上必然存在相交;提出映射分类算法,分析了激光有效散射点的分布情况,结合激光大气散射特征,得出了地基观月系统与激光通讯系统的最优布局。有效散射点对应的散射强度分布与激光全向散射分布的变化趋势一致,证明了文中所提方法的正确性。该方法为优化激光源与观测设备的配置问题提供了新的工程思路。

In order to optimize the layout problem between lunar observing ground system and laser communicating system,it is essentially to avoid higher radiation intensity from laser scattering energy in the detector of lunar observing ground system. STK is used to demonstrate that the space is intersecting between the detecting regions of lunar observing ground system and laser propagation regions. A mapping classification algorithm is suggested to analysis the distribution of laser scattering valid points. Combining with laser scattering atmospherically characteristics,the optimized layout is obtained. The trend of laser scattering intensity distribution based on laser scattering valid points is in accordance with laser total scattering distribution,demonstrating the correctness of this method. The result provides a new effective engineering method to optimize those problems between laser sources and observation system.
