摘　　要：二维态势显示子系统是无人机编队仿真系统的独立节点,分析了组件式GIS开发的特点和不足,从操作系统API层设计了具有GIS特性的二维态势显示子系统,实现了数字地图生成/编辑/缩放、鹰眼浏览、想定注入等功能,对数字高程模型数据进行了预处理和二维可视化;使用改进的双缓存方案解决了运动实体闪烁的问题;网络通信基于HLA/RTI实现,但对于态势信息等数据量大且交互频率低的数据,采用XML文件交互。仿真结果表明,和组件式开发相比,系统具有很好的灵活性和运行效率。two-dimension Plan View Display （PVD） subsystem was one of the simulation nodes of UAVs formation flight system. The features and drawbacks of component-based developing approach with commercial Geographic Information System （GIS） software were analyzed. A two-dimension PVD subsystem was designed at the API layer of V^ndows OS and had GIS features： digital map create/edit/zoom, eagle-eye overview,, scenario input, etc. The DEM data was pretreated and visualized Twinkle problem of the moving entity was solved with an improved dual-cache approach. Network communication was designed under HLA/RTI construction. The data amount of scenario was large but not exchanged frequently. These data were communicated by extensible markup language （XML） files instead of HLA/RTI. Simulation results demonstrate that, compared to the component-based developing approach, the proposed scheme is more flexible and effective.
