Abstract

In this paper, radiation spectrum design methods of material were proposed. Effect of temperature and atmospheric transmission on the infrared radiation transmission of materials was studied. The radiation properties of different materials were analyzed at different temperature. The transmission of aircraft surface materials infrared radiation was studied, according to the environment and the radiation transmission. Moreover, the spectrum of the two materials with the consistent emissivity was studied. Material has less radiation characteristic peak within the 3.0−4.3 μm and low radiation intensity within the 8−14 μm, which has good spectral stealth properties at 250−450 K. The radiation spectrum peak of the material was not obvious within the 4.3−8.0 μm owing to the low transmittance of atmosphere. In conclusion, research results have good significance for the spectral stealth design of materials, and can potentially be used in infrared spectral stealth technology and equipment.
