摘　　要：随着电子对抗仿真技术应用的不断深入,用户对电子对抗仿真环境的要求越来越高。仿真引擎是仿真系统内驱动模型运行的核心组件,直接影响到仿真的逼真性与仿真效率,传统的仿真引擎技术采用单一推进机制,适用范围有限、仿真效率不高。为了提高离散事件仿真的效率,同时降低仿真引擎对计算机网络条件的依赖,发展了一种基于混合推进的多线程并行离散事件仿真引擎,采用多线程并行方式加载与解析仿真方案,提高了数据加载与解析的速度,采用混合推进机制减少了算力开支与时间成本,提高了离散事件仿真的效率。同时实现了仿真引擎与模型的解绑,仿真引擎能够根据事件类型灵活加载模型组件,拓宽了其适用范围。最后,通过具体仿真实验案例的验证,证实了所提方法的可靠性与应用潜力。With the continuous deepening of the application of electronic warfare simulation technology,users have higher and higher requirements for the electronic warfare simulation environment.The simulation engine is the core component that drives the operation of the model in the simulation system,which directly affects the verisimilitude and efficiency of the simulation.The traditional simulation engine technology uses the single propulsion mechanism,which has a limited scope of application and low simulation efficiency.In order to improve the efficiency of discrete event simulation and reduce the dependence of the simulation engine on the computer network conditions,this paper develops a multi-threading parallel discrete event simulation engine based on hybrid propulsion.It used the multi-threading parallel mode to load and parse the simulation scheme,which improved the speed of data loading and parsing.The hybrid propulsion mechanism reduced the computational cost and time cost,and improved the efficiency of discrete event simulation.At the same time,it realized the unbinding of the simulation engine and the model,and the simulation engine could flexibly load the model components according to the event type,which broadened its scope of application.Finally,the reliability and application potential of the proposed method were verified by the specific simulation benchmark.
