基于制导武器的分布式半实物仿真系统研究

应导弹动态性能指标检验的迫切需求,开发了基于制导武器的分布式半实物仿真系统。充分利用仿真模型构建一体化思想,将整个半实物仿真系统按其功能划分成若干个网络节点,采用弹道仿真工作站集中式分布的星形结构进行分布式系统仿真。仿真软件借鉴Windows操作系统消息、事件驱动方式,采用客户/服务器运行机制,基于VC＋＋软件开发工具实现了半实物仿真系统中的数据采集、视景驱动的多线程开发,修正了视线角误差,从而确保了导弹动态性能检测精度;实现了导弹攻击过程可视化仿真,较准确地再现了制导武器在不同干扰条件下的攻击过程。

Research of Distributed Hardware-in-the-loop Simulation System Based on Guided Weapons

In terms of the dynamic performance test requirement of guided missile,a distributed hardware-in-the-loop（HILS）simulation system was developed based on guided missile.It was be fully utilized to integration modeling and simulation idea,the whole HILS was distributed into several nodes to carry out distributed system simulation,the trajectory simulation workstation centralized in distributed star-shaped fram.According to the advanced design idea of the windows operation system message and event drive,using client / server mechanism.Muhithreading programmers were developed for real-time data acquisition,the driver of Vega Prime on the software developed tool of the VC＋＋.This realized the visual simulation of guided missile＇s attack.Meanwhile,error correction is presented for Radar-Targe LOS angular,represented accurately the flight process of guided missile under the condition of different interference.
