空间通信中影响电波传播的因素分析

An Analysis of the Factors that May Affect the Electromagnetic Wave Propagation in the Space Communications

航天技术和网络通信技术的发展使卫星间、卫星与地面之间的组网越来越具有可行性和现实需要,为探索其组网方式,对该网的物理层特性进行系统研究,对空间链路中可能影响电波传播的各种因素进行了分析和总结,首先分析了自由空间、大气、电离层等一般因素,其次还分析了天线、空间环境、敌方攻击等特殊因素的影响,为确保航天通信的可靠性和网络管理的有效性提供了理论依据。

Technical development of spaceflight and network communication make inter-satellite,satellite-ground networking into feasibility and reality.In this article,physical layer of the network is by the numbers investigated.In the space links,all kinds of factors that may affect propagation of electromagnetic wave are researched and summarized.Firstly the general factors are analyzed such as free space,atmosphere and ionosphere,secondly the especial factors are investigated such as antenna,space environment and enemy assault so that it can provide theoretical basis to ensure the reliability of space-terrestrial communication and validity of network management.
