射频仿真系统中多机系统的实时通信

射频仿真系统（ＲＦＳＳ）主要是用在实验室里模拟空中射频目标信号。本文提出并实现了一种应用于ＲＦＳＳ的多机实时通讯系统。该系统基于自行设计的异步并行通讯卡，采用树型分级拓扑结构，并开发了相应的实时通讯协议。为保证仿真的逼真性，着重研究了如何保证通讯的实时性、可靠性这一关键技术，使系统具有效率高、工作可靠、通用性强等特点

Real-Time Communication of Multicomputer Systems in Radio Frequency Simulation System

Radio frequency simulation system(RFSS) is mainly used to simulate echo signal of radio frequency target in laboratory. This paper realizes a kind of multicomputer real time system applied to RFSS. Based on the self developing asynchronous parallel communication card the system, adopts a tree or hierarchical topology structure and develops a real time communication protocol. This paper has paid attention to that technique is used to make the real time and reliable communication available, so the system has the features of high efficiency, reliable operation and generality.
