跟踪雷达三维场景显示系统的设计与实现

DESIGN AND IMPLEMENTATION OF 3D SCENE DISPLAY SYSTEM OF TRACKING RADAR

针对局部战争中对作战细节可视化的迫切需求,为实现全方位监视雷达视野中目标的表现姿态和运动情况,弥补传统雷达显示终端对三维空间信息表现不直观,画面单一等缺点,研究雷达信息的三维可视化显示,模拟真实的战场环境。提出利用OSG渲染引擎,以三维场景态势的构建和管理为核心,对目标模型动态加载、地面火力攻击显示以及空中目标实时变换、多样化视点等关键技术进行优化,设计和实现一种跟踪雷达三维场景显示系统。系统运行结果表明其具有良好的性能,能根据雷达信息完整地模拟出实时、逼真的三维场景显示效果。

In order to satisfy the urgent demand for detailed battlefield visualization in local wars,also in order to achieve comprehensive surveillance of targets＇ performance posture and movement situation in the radar field and make up for the disadvantages like being unintuitive about 3D space information on traditional radar display terminals,using OSG rendering engine,with 3D scene situation construction and management as its core,the paper designs and implements a tracking radar 3D scene display system. The system implements the dynamic loading of large scale terrain model,ground fire attack display and air target real-time transformation,varied viewpoints and other fundamental technologies. System operation results show that it bears good performance and can completely simulate real-time and vivid 3D scene display effects according to the radar information.
