摘　　要：提出了一种基于元语的语义描述仿真运动模型的构造方法,该方法已经应用在航管雷达模拟机、航管程序模拟机和塔台视景模拟机的空中目标和地面目标的运动模型的构建.该方法建立的模型扩展性和可维护性较基于传统的基于过程和面向对象的建模方法要好.In this paper, the authors propose a modeling method of primitive-based semantic description, by which simulated objects＇ moving model is built. The authors have successfully applied the method in in-air and on-ground objects of radar simulator, pseudo radar simulator and tower scene simulator of Air-traffic management. The expansibility and maintainability of models built by this way is better than that built by traditional procedure-based or object-oriented methods.
