摘要
文章介绍了激光通信、太赫兹通信和量子通信等新的通信频段及通信体制在天基信息传输分发体系中的应用前景。激光通信链路可用于构建未来空间骨干网,附加在激光链路上的量子光通信链路可以极大提升链路保密性能,太赫兹通信链路可能在未来卫星星座及伴随飞行集群内部高速数据交换场合提供大带宽及灵活组网的通信能力。各种新形式的链路技术结合起来,可以为天基信息传输分发系统提供支撑。
Laser communication, terahertz communication and quantum communication are prospected in space information transmission and distribution systems. Laser communication links can be used in the construction of the backbone of the future space networking. The quantum links adding to the laser links can greatly increase the communication secrecy. Terahertz links can be used in communications between nodes in satellite constellation. They offer large bandwidth and flexible net connecting. These novel techniques can play an important role in future space information transmission and distribution systems.
