| 摘 要： | 综合考虑烟幕的衰减作用和自身辐射，提出了一个可用于浸没于均质烟幕中场景的红外成像仿真计算的烟幕模型。从理论和红外场景成像仿真计算了烟幕的遮蔽率随衰减系数、观察距离、目标温度和烟幕等效温度的变化关系。理论推导表明烟幕的遮蔽率与衰减系数和观察距离相关，而与目标温度和烟幕等效温度无关；成像仿真结果则表明误差系数和观察距离对遮... |

| Abstract: | Based on the self-emission and the radiation attenuation function,an infrared screen smoke model for imaging simulation of infrared scene in even smoke media was proposed.The screening efficiencies related to the observation distance,the attenuation coefficient,the object temperature and the smoke equivalent temperature were calculated by theory and scene imaging simulation.Theoretically,the screen efficiency is relative to observation distance and the smoke attenuation coefficient,but is independent of the... |
