Real-time Integration of Anti-missile Hardware-in-the-loop Radar System and Mathematical Simulation Model

基于VxWorks和高层体系结构(HLA),采用射频注入式仿真方法,对反导防御系统对目标进行探测、跟踪、识别、拦截和数据通信的全过程进行实时仿真集成。实验中干扰机为实装设备,雷达为半实物设备,其它均采用数学仿真模型。按照实时性约束采用三层体系结构:非实时层、弱实时层和强实时层。给出了系统的设计框架,重点分析了各关键数学模型的工作原理。实验结果表明,采用该体系结构能够有效地将实物设备、半实物设备和数学仿真模型集成起来,具有低成本、高效率、实时性和可靠性的特点。

Based on VxWorks,High Level Architecture（HLA）,and radio frequency injection method,a real-time simulation system which could simulate the detection,tracking,recognition,interception,and data communication processes of a ballistic missile defense was integrated.The jammer was an actual armament and the radar was a hardware-in-the-loop facility.All the other elements were replaced with mathematical models.The whole system could be categorized into three architectures,i.e.,non-real-time,real-time,and strong-real-time layers.The block diagram was proposed and the operating principles of key mathematical models were analyzed in great detail.The experiment indicates that this architecture can integrate the mathematical models with the hardware facilities well.The whole system has the advantages of low cost,high efficiency,real-time operation,and high reliability.
