摘要
传统的PPI显示器仅能显示二维信息,缺乏高度信息,不能直观显示三维信息,而三维雷达显示器以立体的方式显示雷达信息,能给观察者提供更多、更丰富的信息。文中设计了三维雷达显示器的系统总体方案,并针对方案介绍了相应三维显示的透视投影与视见体、多分辨率地形四叉树表示、三维目标模型显示等关键技术,以及系统仿真的流程。仿真结果表明三维显示器的效果很显著,系统方案可行,为三维雷达显示器的进一步研究与实现提供了良好的基础。
Traditional PPI display can only show 2 D information without height information and the 3 D information cannot be show directly. But a 3D radar display can show three-dimensional radar information. This it provide more information to observer. A concept of 3D radar displayer is designed in this paper. The basic principles include perspective projection , multi-resolution terrain render, 3D object model display and the system simulation flow are introduced. The simulation resuh proves that 3D display has good effectiveness, and the system concept is feasible. It would provide a foundation for the 3D radar display and its realization.
