红外导引头动态场景仿真技术(英文)

Dynamic scene simulation technology for infrared seeker

红外导引头硬件测试的重要性促进了目前大量红外动态场景仿真技术的发展,红外动态场景仿真技术包括动态红外仿真器技术与红外场景仿真技术。红外场景发生器主要有电阻阵列、液晶光阀(LCLVS)、激光显示器、激光半导体阵列、红外CRT和数字微镜(DMD)等。DMD对导引头的性能测试可提供较高的性能指标,而该类型的红外场景发生器正在不断发展之中。红外场景生成可分为数据生成与编程阶段。三维目标模型采用Multigen Creator完成,而场景生成采用Vega完成。Vega的Sensor Vision模块可以提供大气模型参数以及目标纹理材质。

The importance of hardware-in-the-loop infrared seekers testing with realistic infrared scenes accelerates the development of the current technologies used in dynamic infrared scene simulation. Infrared seeker dynamic scene simulation technology includes dynamic infrared simulator technology and infrared scene image generation technology. Infrared simulator includes resistor arrays, liquid crystal light valves （LCLVs）, laser writers, laser diode arrays, CRT and digital mirror devices （DMD）. The DMD approach may provide high performance index for testing seekers. Other technologies such as resistor arrays, LCLVs, laser diode arrays, and the CRTs are still under development. Infrared scene generation can be divided into the stage of data generation and programming. Target 3D model is completed by the software of Multigen Creator and dynamic scene image generation is completed by the software of Vega. The SensorVision module of Vega can supply the atmosphere model parameter and target texture material.
