| 摘 要： | 由于月球曲率的影响,月表无线电波的传播需要考虑传播路径上的月面反射多径损耗和障碍物绕射损耗.根据惠更斯-费涅尔原理,文章针对月球曲率较大等特征,分别采用标准多径干涉和绕射算法及SEKE算法,对月面反射多径干涉、障碍物绕射等基本模型的应用判据进行研究,建立了基于以上两种算法的沿光滑月表的电波传播模型,并通过仿真算例对两种...

| Abstract: | Because of the influence of lunar curvature,the lunar-surface radio wave propagation loss should consider multipath and diffraction losses.Based on Huygens-Fresnel principle,the basic loss-models’ applicable conditions are researched,and two models of lunar-surface radio wave propagation are provided and analyzed.These two models,one is based on the standard multipath and diffraction algorithm,and the other is based on the SEKE algorithm,can be considered as a simulation and analysis tool for lunar-surface communication project,and the results of simulation provide theoretics reference. |
