摘要
分析了雷达电子战信号级仿真系统存在的运算瓶颈问题,提出一种基于前后台架构的并行仿真系统设计思路,通过前台仿真显控与后台仿真运算在物理上的分离,解决模型显控与模型运算的资源争夺及人机界面显示耗时问题,而后台的集中式仿真运算,既能通过共享内存的数据交互方式,解决网络数据通信传输耗时问题,也能充分利用高性能计算资源优势,通过并行计算技术,解决信号级装备模型运算耗时长的问题。针对仿真系统构建中需要重点关注的2个技术问题,给出了具体的解决思路,并在此基础上构建了仿真原型系统,针对不同硬件资源进行了仿真运算速度测试,测试结果表明该并行仿真系统架构对仿真运行效率有大幅度提升。
The calculation bottleneck of radar electronic signal level simulation system is analyzed,and a design idea of parallel simulation system based on front-end and back-end architecture is proposed.Through the physical separation of front-end simulation display control and back-end simulation operation,the resource contention between model display control and model operation and the time-consuming problem of human-machine interface display are solved.The centralized simulation operation in the background can not only solve the time-consuming problem of network data communication transmission through the data interaction mode of shared memory,but also make full use of the advantages of high-performance computing resources to solve the time-consuming problem of signal level equipment model operation through parallel computing technology.In view of the two key technical problems in the construction of simulation system,the specific solutions are given.On this basis,the simulation prototype system is constructed,and the simulation speed is tested for different hardware resources.The test results show that the parallel simulation system architecture has greatly improved the simulation efficiency.
