摘　　要：本文提出一种对飞行中的飞机蒙皮进行辐射测量和温度反演的方法。首先建立蒙皮辐射模型、大气传输模型和绝对辐射校正模型,然后推导出温度反演的公式,使用逐次逼近法计算蒙皮温度。在理论分析的基础上,使用8~12μm的宽波段长波红外相机进行试验验证和温度反演,对反演温度的不确定度计算并进行修约,得到5 km飞行高度的民航飞机蒙皮温度的修约结果为268 K,修约不确定度为4K,修约相对不确定度为1.49%。论文研究工作对获取飞机目标红外辐射特性有重要参考价值。This paper presents a method for radiation measurement and temperature inversion of aircraft skin in flight.Firstly,the skin radiation,atmospheric transport,and absolute radiation correction models are established.Then,the formula of temperature inversion is deduced,and the skin temperature is calculated by successive approximation.Based on theoretical analysis,a wideband long wave(infrared)camera that can image light of wavelength 8-12μm is used for experimental verification and temperature inversion.By calculating and modifying the uncertainty of inverted temperature,the result of modifying the skin temperature of civil aircraft at 5 km flight height is 268K;the uncertainty of modifying is 4 K,and the relative uncertainty of modifying is 1.49%.The research work of this paper would be useful for acquiring infrared radiation characteristics of aircraft targets.
