In recent years, the hyperspectral imaging technology sees a rapid development and is widely applied in the military field, with great opportunities for military reconnaissance and unprecedented challenges for military camouflage. This paper analyzes a specular like detection technology for disguising the threat of the stealth technology and the difficulties in the traditional hyperspectral camouflage materials and technology. The researches of the hyperspectral camouflage materials and technologies for simulating the vegetation background are reviewed, focusing on four material systems:The plant camouflage technology, the biomimetic camouflage based on inorganic pigments, the biomimetic camouflage based on the chlorophyll and the "ecological camouflage" based on living organisms. The shortcomings of the existing hyperspectral camouflage materials and techniques in the biomimetic camouflage technology are analyzed. It is shown that the bionic materials cannot accurately simulate the characteristic absorption peak of the green vegetation, the stability and the durability of the biomimetic materials are poor, and the overall thickness of the materials is large, which is difficult to realize in the practical large-scale application. On this basis, a camouflage strategy is put forward to use the "ecological camouflage" based on living organisms. It is proposed that the future development direction and the trend of the hyperspectral camouflage materials and technology are to improve the "bionic camouflage" technology and optimize the "ecological camouflage" technology.
