天基雷达大型可展开相控阵天线及其关键技术

高分辨率成像和动目标识别已成为当今世界先进国家天基雷达的发展趋势,为达到相应技术指标,天基雷达需要大口径、轻量化、可展开而且收拢体积小的有源相控阵天线.文中介绍了国外该型天线的研制发展情况,就其中的关键技术进行了简要分析,为进一步天基雷达天线的研究应用提供参考.

Large Deployable Phased Array Antenna for Space-based Radar and Its Key Techniques

Much attention is paid on the high resolution imaging and moving target indication in the development of advanced space-base radars.To satisfy the requirements for technical specification,the deployable active phased array antenna with large aperture,light weight and less volume after dismantling is required for the space-based radar.The development status of this type of antenna is introduced,and some key techniques are also analyzed in brief,which can be taken as the reference for further research of space-based radar antenna.
