摘要
上行发射组阵可为航天任务提供高效费比服务,并且具有灵活、可靠、规模可辨以及可扩展等优点。给出了上行发射阵列的系统概念与设计,讨论了其中的关键技术,提出了未来的发展方向与建议。
Transmit arraying is a promising approach to achieve very high EIRP for deep space communications without using extremely large antennas and extremely high -power transmitters. Transmit arraying is flexible, reliable, scalable, evolvable andcan provide redundancy. In this paper, a system concept is presented, and key technologies of the system are discussed. Finally, some future research aspects and suggestion are provided.
