摘　　要：船载以及海岸目标的辐射特性测量是目标红外辐射特性测量领域的重要组成部分,采用传统模式修正大气透过率远远满足不了红外辐射特性测量精度的要求。为了最大限度地提高辐射特性测量的精度,提出了基于参考源测量目标辐射特性的方法,并利用口径为600mm的长波红外辐射特性测量系统,在近海岸进行红外辐射特性测量实验。结果表明:该方法的辐射测量误差可减小到4.31%,优于传统方法的反演精度。The measurement of infrared radiation characteristics of ship and coastal targets is among the most important components of target infrared radiation characteristic measurements.The traditional ground model corrects only the atmospheric transmittance,so the measurement error of the target cannot meet the measurement requirements of infrared radiation characteristics.This study proposes a method that measures the target radiation characteristics based on reference sources to maximize the measurement accuracy.Experiments for infrared radiation characteristic measurements are conducted near the coast by using a long-wavelength infrared radiation characteristic measurement system with an aperture of 600 mm.Experimental results confirm that the proposed method reduces the radiation measurement error to 4.31%,which is higher than the inversion accuracy of the traditional method.
