| 摘 要： | 对于红外成像制导仿真而言，无论是半实物仿真还是数学仿真，关键在于红外序列图像的生成．该文介绍通过OpenGL模拟海天背景下舰船目标的红外序列图像．首先对舰船目标进行三维建模，分析目标背景的温度场和红外辐射特性，同时通过Lowtran7软件来计算大气传输中的辐射衰减，对得到的辐射量进行量化，最后利用双缓存技术实现红外图像的动态生成．

| Abstract: | For infrared imaging guidance simulation, the key problem is the generation of infrared image sequences in either semi-physical or mathematical simulation. The infrared image of a ship target in the sea-sky background through OpenGL was illustrated. By three-dimensional modeling of the ship target, the temperature field and infrared radiation characteristics of target background were analyzed. Then the radiation attenuation of atmospheric transmission through software Lowtran7 was calculated and the radiation value was quantified. Finally the dynamic generation of infrared image was realized by adopting double buffer technique. |
