可应用于小卫星的方向回溯天线研究

Research on retro-directive antennas for small satellites

方向回溯天线因为其结构简单,成本低的特点,越来越被研究者所重视。随着研究的深入,研究者提出了多种多样的体系结构,功能也逐渐完善,可应用的方向也越来越多。文章对方向回溯天线的发展历史作了简单的回顾,介绍了几种典型的,具有代表性的方向回溯天线类型,包括Van Atta阵列、共轭混频阵列和相位检测阵列,针对相位检测阵列应用于小卫星星间链路提出了一种可行方案。文章的最后对方向回溯天线的研究方向进行了简单总结。

Due to the advantages of simple structure and low cost,retro-directive antennas have attracted extensive interest among researchers.Numerous architectures of them have been proposed,which have a huge development space and brighter future.This paper briefly introduces the recent progress in retro-directive antennas including Van Atta arrays,conjugate mixing arrays,and phase detection arrays,followed by the conception of applying retro-directive antennas to small satellites.Finally,we conclude by providing our opinions of future developments in retro-directive antennas.
