The Study on Infrared Stealthy of Variable Emissivity Materials Based on the Radiation Contrast

Abstract:

The infrared stealth coating with changeless emissivity is impossible to implement ships infrared stealth all the time. According to this characteristic, the range of target surface emissivity can be acquired from the calculation and analysis of target and background infrared characteristics with the radiation contrast should be less than 0.04. Using electrochromic materials to change the average emissivity of target surface in 3:5μm and 8:14μm wavelength can mainly meet the target infrared stealth all the time. It has a big improvement in the stealth efficiency compared to the infrared stealth coatings with changeless emissivity.
