Progress on Hyperspectral Camouflage Materials and Techniques for Spectral Characteristic Simulation of Green Vegetation

Hyperspectral imaging technologies have put forward newer and higher requirements for camouflage and stealth technology. By studying the spectral characteristic simulation technology of various green vegetation, new ideas can be explored to solve the problem of target camouflage under hyperspectral imaging reconnaissance. This paper summarized spectral features of greenery in the visible-near-infrared band as well as the thermal infrared band, and analyzed the formation mechanism of its spectral property in those two bands. Furthermore, the research progress on the hyperspectral camouflage materials and techniques for simulating the spectral characteristics of green vegetation in recent years were described. Based on the analysis of the disadvantages of the existing hyperspectral camouflage materials and technologies, the development direction and trend of hyperspectral camouflage materials and technologies for simulating the spectral characteristics of green vegetation were proposed.
