| 摘 要： | 针对飞行器红外探测过程的成像仿真，有助于红外隐身效能的评估，进而提高应对红外探测的反侦察能力。建立了飞机红外成像仿真模型，并针对不同的飞行姿态、速度以及不同的探测时间，求解其蒙皮温度与红外辐射亮度，结果表明当飞机从低速到高速运行时，太阳辐射条件与气动加热层温度分布分别成为影响其成像结果的主要因素。建模方法及仿真结果对飞行器的隐身设计具有指导意义，为飞机实时红外成像场景的生成提供理论基础

| Abstract: | The imaging simulation for the infrared detection process of the aircraft contributes to the evaluation of the infrared stealth performance, thereby improving the anti-reconnaissance ability to deal with infrared detection. The aircraft infrared imaging simulation model was established, and the skin temperature and infrared radiation brightness for different flight attitudes, speeds and detection moments were solved. The results show that when the aircraft runs from low speed to high speed, the solar radiation conditions and the temperature distribution of the aerodynamic heating layer become the main factors affecting the imaging results. The modeling method and simulation results proposed have guiding significance for the stealth design of the aircraft, and provide a theoretical basis for the generation of real-time infrared imaging scenes. |
