英文摘要	The constantly increasing progresses of multi-spectrum detection technology, as well as the diversification of the natural background, have necessitated the need to devise new camouflage coating approaches. The conventional camouflage coating technology that is limited to the visible light band is far from being suitable for the combinational detection of visible, infrared, and hyperspectral light. Along these lines, in this work, a novel concept idea is proposed to fabricate multispectral camouflage coatings based on the design of the core unit. The underlying idea is to employ various coatings in order to address the broadband reflectivity characteristics of the natural background in a wide frequency range, which cannot be attained by employing a single-spectrum coating material. Moreover, the combined design and application of single-spectrum coatings could be in the unit suitable range to be consistent with the characteristics of the natural background of visible light/infrared/hyperspectral. The core unit design elements incorporate the characteristics of single-spectrum coating materials, the employed ratio of various single-spectrum coatings, as well as the camouflage patterns and camouflage basic unit sizes. Besides, the performance of the final multispectral camouflage coatings is evaluated by the color difference, the hyperspectral reflectivity curves, the master saliency maps, and the edge characteristics. Based on the hybrid background of both vegetation and desert, various single spectral coatings including visible light coatings (green and brown) with suitable hyperspectral characteristics and infrared coatings with different emissivity in the waveband of 8-14 mu m were selected for the production of multispectral camouflage patterns in a fixed-size (1 x 1 m(2)) substrate. More specifically, the camouflage patterns possess rectangular and hexagonal shapes with a basic size of 5 cm in diameter. Finally, the as-prepared multispectral camouflage coatings were measured in different airspace conditions (12-42 m). Compared with both the pure Al plate and the multispectral camouflage coating with rectangular patterns (M2), the proposed multi-spectral camouflage coating with hexagonal patterns (M1) exhibits optimal compatible stealth performance in the coupling bands of visible light and infrared wavebands.
