Ionospheric Action and Effect on Modern Radio Systems

本文综述了现代无线电系统中的电波与电离层相互作用,论及电离层起到的作用和影响,尤其是在地空无线电系统中的作用和影响。介绍了电离层产生的传播效应及在具体无线电系统中的影响及其对策;电离层的模式预报和可能的修正技术。最后,还阐述了电离层研究的新动向和发展前景,重点叙述了电离层有源变态技术及其应用的展望。

The ionospheric action and effect on modern radio systems,especially on the Earth -space propagation have been described in this paper.The main ionospheric Characteristics and their propagation effects on various space and terrestrial systems are also presented.The ionospheric models,prediction methods,and some real-time correction techniques are discussed.Finally,the paper indicates the development tendency of ionospheric investigation,and emphasizes the artificial modification of the ionosphere and its applications.
