中文摘要: 针对经典无线电波传播模型不适用于月球特殊的传播环境问题,提出一种月表环境下电波传播损耗分段预测模型。该模型首先建立包含自由空间段、月面反射段和月球绕射段的理想分段预测模型,并给出不同区间内传播损耗预测算法,然后考虑传播路径剖面上多重障碍物导致的额外损耗,以及其对分段区间参数的修正方法。将其应用于美国国家航天局提供的月表实际场景,仿真结果表明,该模型预测结果与“阿波罗”登月工程获得的实测数据非常吻合,可用于辅助月表无线通信系统的参数设计和性能评估。
Abstract:Most of the traditional radio models are invalid due to the special propagation environment on lunar.A novel path loss prediction method for lunar surface was proposed. Firstly,a theoretical segment model according to communication distance was established and three propagation scenarios were analyzed. Then the multiple isolated obstacles on propagating path were considered, which would not only lead to an additional transmission loss but also affect the segment parameters. The present method was applied on a real lunar surface scenario provided by National Aeronautics and Space Administration (NASA). The simulation results showed that the prediction results are very close to measurements by Apollo project. This segment prediction model could be very useful on system parameters design and performance analysis of lunar communication system.
