摘　　要：介绍了一种机载有源相控阵雷达波束控制器的设计。在机载有源相控阵雷达波束控制系统的设计中 ,除了保证系统所要求的波束转换速度外 ,还需要对波控机进行小型化设计 ,因此 ,小型化、高速度、高可靠性与灵活性是该类雷达波控系统设计的关键技术 ;相位计算时将坐标原点设在二维平面的中心 ,然后将二维平面均分为 4块 ,每一块定义为一个象限 ,用 4个硬件相同的模块来构成全硬件、可编程的波控机。波控机采用了大容量的Flash存储器 ,使天线系统初始的相位和幅度可以在线编程。完成了天线阵近场的联试及整个雷达系统的外场联试 ,同时在某机场观察到目标。The design of beam-controller of airbone active phase array radar is introduced in this paper.Except to ensure beam conversion speed required by the system,miniaturized design is needed yet.Therefore ,miniaturization and high speed,high reliability and agility is key techniques for this kind of radar.The coordinate origin is set in center of two dimension plane during phase calculation,then share out two dimension plane into four blocks,each block is defined to one quadrant,four modules with same hardware are adopted to contruct of the full hardware and programmable beam-controller. The beamcontroller adopts flash memorizer with great capability,Then,the on-line programming for the initial phase and amplitude of the antenna system can be carried out.The near field test for the antenna array and the outfield test for whole radar system are finished.The target in the airport can be observed.
