数字阵列收发组件FPGA远程配置的研究与实现

数字阵列雷达(DAR)正成为相控阵雷达的一个重要发展方向,数字阵列收发组件(DAM)是其核心。针对数字阵列雷达DAM模块数量众多,通常与阵列天线集成安装在舱外导致调试困难的实际情况,给出了一种数字阵列收发组件现场可编程门阵列(FPGA)远程配置的设计方法,利用Flash存储配置数据、CPLD产生配置时序和通信接口、复用系统通信光纤,较好地解决了DAM模块远程调试的难题,动态重构技术的应用极大地提高了系统的试验效率,在某数字阵列雷达演示验证项目中得到成功应用,取得了良好的效果。

Realization of FPGA Remote Configuration of T/R Modules for Digital Array Radar

Digital array radar(DAR) becomes an important development direction of phased array radar.The digital array T/R module(DAM) is the core of DAR.Digital array radar has a large number of DAM modules,which are usually integrated with the array antenna and installed outside the aircraft.This results in difficulties in debugging.A design method for FPGA remote updating and configurating files is presented in this paper.Flash memory is used to store configuration data and CPLD device to generate FPGA configuratio...
