认知航天测控系统探讨

Exploration of Cognitive Space TT&C Systems

针对航天测控系统面临的频谱资源紧缺和抗干扰等问题,首先结合认知无线电系统组成及关键技术,分析基于认知无线电技术的航天测控系统优势,并探讨开展认知航天测控系统研究的必要性,然后提出一种基于认知无线电技术的认知航天测控系统,并设计与其相对应的认知航天测控网络架构。最后,针对航天测控系统特点,初步分析建立认知航天测控系统所需的关键技术,为该系统的深入研究提供一定的参考。

The space TT＆C system is facing some issues, such as the crowding spectrum resource and the anti-interference problem. For that, this paper analyzes the cognitive radio systems and the key technologies, and studies the advantages and essentiality of the cognitive space TT＆C system based on cognitive radio technology. Then, the paper presents a cognitive space TT＆C system, and describes its network architecture. At last, the paper discusses the key technologies of cognitive space TT＆C system, which provides some reference to the further study.
