太赫兹技术的飞速进步已经展现出对空间信息领域的积极影响。介绍了太赫兹波的特性及其现有的应用,展望了太赫兹技术在空间信息领域的应用前景,具体分析了太赫兹频段在空间信息获取和空间信息传输两个领域的技术优势。目前,空间科学观测已扩展至太赫兹频段,太赫兹频段雷达可提供高分辨率的着陆场图像及优秀的探测预警性能,太赫兹频段链路可用于航天器集群间通信、航天器内部高速无线通信,并有望成为有效突破等离子体黑障的测控通信手段。
The rapid advances in terahertz technology have demonstrated a positive impact on the field of space information. The characteristics of terahertz waves and their applications are introduced. The application prospect of terahertz technology in the field of space information is also forecasted. The technical advantages of terahertz band in space information acquisition and spatial information transmission are analyzed in detail. At present, space science observations have been extended to the terahertz band. Terahertz band radars provide high-resolution images of landing fields and excellent detection and warning capabilities. Terahertz band links can be used for spacecraft inter-cluster communications, spacecraft internal high-speed wireless Communications, and is expected to become an effective means of measurement and control communication of plasma black barriers.
