摘　　要： 随着系统规模的不断扩大,系统复杂度大大提高,采用单一的仿真程序已不能满足大规模复杂系统仿真的需求,采用分布式结构进行雷达系统仿真逐渐成为一种解决复杂系统仿真的主要方法。仿真引擎机制的研究是雷达仿真系统设计的关键,有利于深化和提升雷达仿真的效率。阐述了雷达仿真系统模型,采用分布式结构,提出了基于消息服务中心MSC和运行监控中心SC两层控制结构的仿真引擎机制,将用户接口服务与消息传递服务分离开来,增强了雷达仿真软件的灵活性和易操作性。在这种机制下,进一步提出了消息传递算法MPA并进行了系统性能测试和验证,仿真实验结果表明,MPA算法可以快速、可靠地实现雷达系统内部各执程体间的互连互通,准确地完成雷达仿真过程的控制与监视。 With the expansion of the scale and the promotion of the complexity of system,using the single simulation program has not been able to meet the demand of large-scale complex system and the method of radar system simulation based on distributed architecture becomes a solution for complicated system simulation.Study on the engine mechanism in distributed architecture is the key for the design of radar simulation and more conducive to deepen and improve radar simulation efficiency.This paper firstly expounded the radar simulation system model and then proposed two level control structures of simulation engine mechanism based on the message service center and runtime monitor center in distributed architecture in order to detach user interface service from message passing service and to enhance the flexibility and usability of radar simulation software.Under this mechanism,it put forward the message passing algorithm（MPA） and made the system performance test and verification.The simulation results show that MPA in this mechanism can fleetly and reliably realize the interconnection and communication between executable processes of radar simulation system and can accurately monitor the course of radar simulation.
