为完成适用于天基测控的箭载共形相控阵天线对波束指向控制的需求,分析了箭载天线波控系统的设计要求与任务,论述了平面相控阵天线波控系统的实现方法,并根据波控系统基本原理推导出基于阵因子函数的箭载共形相控阵天线波控算法。针对运载火箭天基测控这一新需求提出了基于查表法的集中式波控设计方案,给出了系统设计方法。样机测试结果表明,该波控系统方案正确、可行,满足工程需求。

To meet the requirement of rocket-borne conformal phased array antennas used in space-based TT&C for beam steering,the design requirement and task of rocket-borne antenna beam steering system is analyzed,the basic principle of plane phased array antenna beam steering system is introduced,and based on which a rocket-borne conformal phased array antenna beam steering algorithm based on array factor function is deduced.A centralized beam steering system based on table lookup is proposed to meet the requirement of space-based TT&C of carrier rocket,and the system design method is given.The results of prototype testing show that the designed beam steering system meet the requirement of rocket-borne conformal phased array antenna.
