红外成像制导系统虚拟样机

建立了基于三维场景的红外成像制导系统虚拟样机。虚拟样机模型分为成像系统、信号处理、运动控制三个模块。在分析各模块实现的基础上，重点研究了虚拟样机与三维场景之间的运动关系及数据交换过程，并实现了数学建模。利用时间放大方法，探讨了解决仿真中实时性与逼真性之间矛盾的途径。最后，利用三维红外场景数据进行了导弹制导过程仿真试验，并给出系统作用距离与探测概率关系、弹道曲线等仿真结果。

Virtual IR imaging guiding system model

Based on 3D IR scene, a virtual IR imaging guiding system model is established. The model consists of three modules, which are imaging system, signal processing and movement control. Analysis of the three modules is performed with emphasis on the movement relation and data exchange between the virtual system and 3D scene, and mathematic models are given. By use of time amplifying method, a way to resolve the conflict between the real-time requirement and simulation reality is discussed. At the end, simulation experiments are performed and the results show that this model is practical.
