不同发射率红外隐身涂层在典型背景中的伪装效率研究

Research on Camouflage Efficiency of IR Stealth Coatings with Different Emissivity at Typical Background

通过对发射率F为0．42～0．95的迷彩隐身涂层在典型背景中的红外温度和红外热像图的测试分析，总结出不同红外发射率隐身涂层在周日里与典型背景的融合程度，计算了各发射率隐身涂层的伪装效率。对红外隐身涂层的发射率梯度设计和不同发射率红外斑块在目标表面的分布提出了合理化建议。

The fusion degree of IR stealth coatings with different emissivity and typical background in 24 hours was summarized and the camouflage efficiency of each stealth coatings was calculated, through testing analysis of IR temperature and thermal image at typical background for stealth coatings at emissivity ε （ 0.42 - 0.95 ）. The rational proposal for emissivity gradient design of IR stealth coatings and distribution of IR spot with different emissivity on the object surface were provided.
