摘　　要：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 fast development of terahertz techniques is impacting the space information field. The characteristics of the terahertz wave and the applications in existence are analyzed. The applications of terahertz wave in space information field, especially in space information acquisition and transmission, are prospected. The terahertz techniques are hopefully taking advantages in space scientific observation, radar telemetry and imaging, radar early warning, inter-satellite links of constellation, wireless link in space vehicle, and TT＆C link to reentry space carriers and near space hypersonic vehicles without plasma sheath induced blackout interruption.
