基于Vega的红外成像制导仿真技术研究

Research of Infrared Imaging Guidance Simulation Techniques Based on Vega

描述了利用 Vega 进行红外成像制导仿真的方法.并针对该方法在红外成像制导仿真过程中的几个关键技术进行了讨论。为了实时仿真的需要,介绍了在场景建模中建立大面积地形模型的方法;利用建立不同细节度目标模型的方法,满足了红外导引头对目标进行探测、识别和辨识的视觉仿真效果;利用重新定义本地观察坐标系的方法,使得屏幕显示与导引头视场图像相一致。考虑到目前国内在红外成像制导仿真方面的研究较少,本课题结合 Vega 软件进行了仿真,得出了仿真结果。从仿真结果看,该方法取得了较为理想的仿真效果。

A method of the infrared imaging guidance simulation based on Vega is described,and some important tech- nique is discussed in the course of the infrared imaging guidance simulation.For the needs of real time simulation,a method to build the big area terrain model is introduced; In order to obtain view simulation effect that the infrared seek- er detect,recognize and identify to the objective,a method of building the different Level of Details(LOD)model is used.The screen shows is same as seeker view with a method of again definition the local observer's coordinate system. 'Faking account of the research of infrared imaging guidance simulation is little,the simulation is carried out with Vega software and the results are presented.It is can be shown that the simulation method get better effects from the simula- tion result.
