摘要
针对一种新型相控阵传输体制的特点和要求,对相控阵设备中的波束控制单元的实现方法展开研究。设计硬件布局与实现方案,并对基于FPGA和单片机的嵌入式软件架构进行深入分析与讨论,重点研究T/R组件接口模块、定时动作模块等主要功能单元的设计方法,探讨波束控制单元的主要工作流程,给出了完整的设计与应用方案。试验结果表明,依据该方案研制的波控单元试验结果满足新型相控阵体制的信息传输要求。
The beam steering unit for a phased array system is designed,which includes the PCB layout,the chip selection and the built-in software architecture of FPGA and MCU.The research focuses on the design of FPGA modules,such as T/R module interface and action timer.The main flow chart of this beam steering unit and the whole design and application scheme are presented.The test result indicates that the beam steering unit based on this scheme satisfies the transmission requirement of the phased array system.
