基于System Generator的雷达基带信号模拟系统仿真设计

摘要

针对传统雷达信号模拟设备信号样式固定、单一,通用性不足和适应能力差的问题,提出了一种基于System Generator图形化建模手段,利用逻辑控制单元产生ROM读地址,对雷达信号参数进行查表操作的方法,实现雷达基带信号模拟设备各功能模块的建模仿真,采用功分复用思想对功能模块进行合理规划,完成雷达基带信号模拟系统仿真设计,仿真结果表明该系统具有一定的雷达信号样式自定义能力,可为基于FPGA的雷达信号模拟系统的信号级建模与开发提供有力支撑.%In view of the traditional radar signal simulation signal style fixed,single,lack of versatility and adaptability is poor,this paper proposes a graphical modeling tool based on system generator,using logic control unit generates read ROM address,of all parameters of the radar signal is a lookup table operation method,to realize radar signal simulation modeling and simulation of each function module,the idea of work division multiplexing for reasonable planning function module,completes radar baseband signal simulation system simulation design.Simulation results show that the system has certain ability of radar signal custom,for a radar signal simulation system based on FPGA signal level modeling and development to provide favorable support.
