摘要

摘要:本文主要研究卫星系统中用于信息收发的天线系统的设计、建模和研究。结果表明，该发射机功率为85 dBWt的天线阵列能够保证同时提供一个全局波束和多个波束宽度为0.7 × 0.7°的移动卫星通信目标问题。需要补充的是，与使用单相天线阵列形成全局波束相比，形成多波束的优点是:数据速率更高，对地面站天线系统的要求相对较低，无线电链路的抗噪声能力更强，能够动态控制每个波束中的信号功率。

Design, Modelling and Research of an Antenna System for Transmitting and Receiving Information in Satellite Systems

Abstract The work deals with the design, modelling and research of an antenna system for transmitting and receiving information in satellite systems. It was revealed that this antenna array with a transmitter of 85 dBWt is guaranteed to solve the target problem of providing mobile satellite communications with both one global beam and a plurality of beams with a width of 0,7 × 0,7°. It should be added that the advantage of forming multiple beams compared to a global beam with a single phased antenna array is: higher data rate, relatively low requirements for antenna systems of ground stations, greater noise immunity of the radio link, the ability to dynamically control the signal power in each beam.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
