Dynamic scene simulation technology for infrared seeker

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.
