中文摘要：
星载可展开有源相控阵天线作为空间通信、电子侦察、导航、环境监测等卫星系统的＂眼睛＂和＂耳朵＂,通过空间可展开结构实现较大的物理口径,利用有源相控阵体制实现独立控制多个点波束,克服了传统机械扫描天线的诸多缺点,已成为宇航领域的关键装备之一。总结星载有源相控阵天线发展历程,分析星载有源相控阵天线的结构形式、性能要求及应用情况,阐述国内外研究现状,并对其涉及的七项关键结构技术做了概要解析,探讨星载可展开有源相控阵天线结构领域的未来研究方向。
英文摘要：
As the ＂eyes＂ and ＂ears＂ of the space communications, electronic countermeasures, navigation, environmental monitoring and other satellite systems, the spaceborne deployable active phased array antenna achieves a greater physical aperture through a deployable configuration, and implements the individual control of different spot beams using the electronic scan mode. It has been one of the key equipments in the areas of aerospace without the many drawbacks brought by the mechanical scan antennas. The development process of the spaceborne active phased array antennas is introduced. And the configuration styles, performance requirements and engineering applications of the spaceborne deployable active phased array antennas are presented. The international research statuses are described. At the same time, a concise analysis of the seven key technologies of antenna structure field is made. The develop trends of the spaceborne deployable active phased array antenna structural technologies are discussed.
