摘　　要：针对空空导弹制导半实物仿真无法直观模拟载机携带导弹从发射到击中目标的动态过程和仿真数据缺乏直观表现手段等问题,提出建立制导半实物仿真可视化的方法。采用光纤反射内存网络集成的方式,将可视化与制导半实物仿真系统联合进行数据交互;利用制导半实物平台仿真机的实时解算输出来驱动仿真渲染的帧频刷新;程序多线程设计解决了软件架构、实时性优化、碰撞检测、特效生成和导航路径轨迹动态管理等关键技术,实现了多通道多角度观测、多目标选择、实时跟随以及场景回放等功能。仿真结果表明,视景可以在内场高效精确的模拟靶试战场环境和导弹的作战性能,为空空导弹制导系统半实物仿真提供直观、形象的结果判读方法,在评估导弹性能等方面具有积极的意义。For Air-to-Air Missile(AAM)Hardware-In-the-Loop(HIL)simulation system lacks launching and fighting process visually between carrier fighter and missile and absence of simulation data view presentation,a visual simulation is proposed.HIL is associated with visualization for data interaction adopting the method of fiber optic Ethernet.Mainframe frequency is refreshed by using the output of simulation machine.System Framework,real-time optimization,simulation scene design,collision detection,explosion effect and dynamic point of navigation path were settled by multithread program.Viewpoint transform,multiple target switchover,real-time following and simulation playback were achieved.The result shows that battlefield conditions and missile operational performance are simulated efficiently and precisely in the inner test environment.The visual process is fluent,the scene is verisimilitude,which provides an effective method for the missile verification.
