Thermal Camouflage Condition of Infrared Pattern Paint

Based on the criterion of 4K radiation temperature difference,this paper inferred and calculated thermal camouflage condition of infrared pattern paint for the 8~14μm waveband thermal camouflage,including the emissivity difference range of upper surface of target and background Δe_(ts),and the emissivity difference range of spots adjacent to each other on top surface of target Δe_(t12).The paper also discussed the factors influencing Δe_(ts) and Δe_(t12).
