摘　　要：针对月球探测过程中地月通信路径损失大的问题,利用STK仿真软件建立地月通信仿真场景,通过仿真分析了地面站与月球探测器间的链路情况,用于后续对比分析。结合Matlab分析了路径损失情况,深入研究了通过增大天线口径、提高工作频率等方法对路径损失的改善,并通过仿真对比分析了不同措施的效果,指出存在的局限,提出利用新技术弥补地月通信中巨大的路径损失。The communication between Earth and Moon has the problem of large path loss during the Moon exploration.Based on the simulation scene of cislunar communication created by STK,the link between the detector and Earth station is analyzed.The path loss of the link is analyzed with Matlab.The improvement of the means such as increased antenna aperture and enhanced signal frequency is studied.And the limitation is pointed out.Then new technology is proposed to solve the path loss problem.
