摘　　要：波控系统是相控阵雷达天线的一个重要的子系统。相控阵天线的波束合成、捷变以及赋形功能都需要由波控系统调度控制完成。传统波控系统由波控分机与波控单元的独立分级和模块组成,不能满足机载雷达空间尺寸小、速率要求高以及线缆布局轻量化的要求。本文设计并实现了一种基于Serializer/Deserializer(SerDes)总线的波控系统,通过将各模块集成在天线阵面的内部的方式,减小了对体积与重量需求,在模块间使用SerDes总线作为数据传输链路,传输速率达到2Gbit/s的同时大大简化了芯线的连接。对系统/模块的设计、定时同步技术、高速链路设计方法与进行了阐述,最终的天线阵面性能测试结果验证了该系统的可实现性。The beam steering system is an important subsystem for phased array antennas.The functions of phased array antennas such as beam steering,agility and shaping are accomplished by beam steering system.In traditional way,beam steering system are composed by beam steering crate and units.In order to achieve a high-integrated,highspeed and simplify cable layout system suiting airborne phased array radar,a beam steering system based on Serializer/Deserializer(SerDes)is presented on this article.The modules of system are integrated in antenna to reduce the weight and volume using 2Gbit/s SerDes as the transmit bus which can simplify the cable connection.The design of system and modules,timing synchronization and high-speed data link are analyzed.The typical performance of the antenna is tested,which validates the design idea.
