场景导向的雷达系统模型设计与仿真方法研究

Research on scenario-oriented radar system model design and simulation

由于雷达系统工作过程、接口交互目前主要采用文本的形式进行描述,导致了系统的整体验证过度依赖实物,因而带来了验证周期长、设计修正成本高等问题。针对研制过程中存在的问题,采用MBSE思想,开展了以雷达场景为导向的需求分析,并根据雷达系统功能成熟度、复杂度等特点,详细阐述了适用于不同雷达的功能分析方法,重点介绍了雷达系统与分系统的架构设计和三层仿真验证方法,将系统调试阶段的部分验证环节提前到系统设计初期,解决了过度依赖实物的痛点问题,对雷达系统新研制模式的应用具有积极的意义。

Because the working process and interface interactions of radar systems are currently mainly described in the text form,the overall verification of the system has become overly reliant on physical objects,leading to issues such as long verification cycles and high design correction costs.In view of the problems existing in the development process,this paper adopted the idea of MBSE to carry out radar operation scenario-oriented demand analysis.According to the maturity and complexity of the radar system function,it elaborated on the functional analysis methods suitable for different radars,and emphasized the radar system and subsystem architecture design and three-level simulation verification method.By advancing part of the verification link in the system debugging stage to the initial stage of system design,the paper solved the pain point problem of over-dependence on physical objects,which held significant implications for the application of a new development mode for radar systems.
