电离层层析成像技术的研究进展

THE RESEARCH PROGRESS OF COMPUTERIZED IONOSPHERIC TOMOGRAPHY TECHNIQUE

作为日地空间环境的重要组成部分,电离层对无线电通讯、卫星导航与定位以及人类的空间活动有着重要的影响。电离层层析成像技术的出现,为探测电离层的时空结构开辟了广阔的前景。目前,层析成像(Computerized Tomography,简称为CT)技术在电离层探测上的应用还很薄弱,很多具体工作还没有开展。为了对CT技术在电离层探测上的应用有个全面、系统的了解,本文对近年来CT技术在电离层领域的研究及进展进行综述,并对电离层CT技术中存在的问题进行了分析,同时对未来待开展的工作进行了展望。

As the important constitution of solar-terrestrial space environment, ionosphere impacts on radio communication, satellite navigation and positioning and the human＇s space activities. The computerized ionospheric tomography （CIT） technique provides expansive prospects for sounding the ionospheric temporal-spatial structure. Nowadays, the application of computerized tomography technique to ionospheric sounding has its weakness. Many researches have not been carried out. The research progress of CIT is summarized in this paper. Meanwhile, the existed problem of CIT is analyzed, and the future research is forecasted.
