摘　　要：针对星载大型相控阵雷达波控系统设计中面临的重量、布相实时性等难题,给出了一种基于光互连的集总式星载相控阵雷达波束控制方法.该波束控制方法将光纤作为波束控制器传输波控信号给微波组件的媒介,采用集总式架构和可扩充阵列一体化模块,解决了大型相控阵天线通信距离和传输速率、阵面规模和重量体积的双重矛盾,具有传输速率高、体积小、重量轻、模块化、可扩充等优点,对星载大型相控阵雷达波控系统工程设计具有借鉴作用.In order to solve such problems as weight and phase real-time in the beam-steering system designof space-borne large phased array radar, this paper proposes a beam-steering method based on the optical interconnection.In this method the optical fiber is adopted for signal transmission between the beam controller and microwavecomponents, and both lumped architecture and scalable array modules are also used to solve the contradictionbetween communication distance and transmission rate, antenna array size and light weight. The proposedmethod has such strong points as high transmission rate, small size, light weight, modularization, scalability andso on, thus providing a reference for the engineering design of beam-steering system of space-borne large phasedarray radar.
