摘要
介绍了一种雷达信号环境实时仿真系统的硬件架构和软件流程设计方法,其中信号源零槽控制计算机采用Vxworks实时操作系统,其余计算机采用XP系统+实时扩展(RTX)子系统,基于实时网卡和Rapidio通信接口的高速率、低延时特性,构建了一个按50 ms节拍运行的雷达信号环境模拟系统。
This paper introduces a design method of hardware architecture and software flow for the real-time simulation system of radar signal environment.The Vxworks real-time operating system is used in signal source zero slot control computer,while WinXP system+real-time extension (RTX) subsystem are used in other computers.Based on the characteristics of high speed and low delay of real-time network card and Rapidio communication interface,a radar signal environment simulation system running at 50 ms beat is constructed in this paper.
