红外传感器系统的性能取决于系统操作时的环境 ,如复杂的地形、背景环境和大气条件等 ,用传统的飞行试验方法来作为系统性能的测试手段己不适应。采用半物理闭环仿真方法 ,在实验室建目标模拟器 ,可实时产生动态逼真的交战时所观察到的红外场景 ,为具有红外探测能力武器系统在研制、集成、测试、系统性能有效评价、武器系统的开发等方面提供精确可重复的实验途径。仿真系统包括目标特性及与红外场景有关的数据库、图像生成计算机、红外目标发生器、红外场景投影光学系统、飞行模拟器、仿真计算机。目前目标发生器产生的红外图像分辨率已达到 512× 512 ,帧频 10 0Hz ,辐射波段 3～ 5μm、8～ 12 μm ,适用于目前红外制导系统制导过程的分析和评价 The performance of the infrared sensor system depends on the system operating environment, such as complex topography, background environment and atmospheric conditions, etc., with the traditional flight test methods as a means of testing the performance of the system has not adapted. A semi-physical closed-loop simulation method is used to build a target simulator in the laboratory to generate real-time dynamic infrared scene observed during the war. It is an effective tool for developing, integrating, testing and evaluating the system performance of weapon systems with infrared detection capability. Weapons System development and other aspects to provide accurate and repeatable experimental approach. The simulation system includes target characteristics and database related to infrared scenes, image generation computer, infrared target generator, infrared scene projection optical system, flight simulator and simulation computer. At present, the resolution of the infrared image generated by the target generator has reached 512 × 512, the frame frequency is 10 0Hz, the radiation band is 3 ~ 5μm and 8 ~ 12 μm, which is suitable for the analysis and evaluation of the guidance process of the current infrared guidance system
