There are many military camouflage engineering equipment, such as camouflage net, camouflage paint, camouflage smoke screen, fake target and so on. The two complement each other, and the isomorphism of * * * has become the material basis for hiding people's eyes and ears and exposing falsehood in modern military camouflage engineering. This paper focuses on the camouflage net.
During the revolutionary war years, our army did not have a standard camouflage net. In the war, we can only use some convenient materials for some simple camouflage. Later, in the War to Resist U.S. Aggression and Aid Korea, our army made a lot of camouflage nets modeled on the cotton and linen camouflage nets of the Soviet Union, but they could only be used against visual inspection. China's self-made standard camouflage net was first produced in the 1960s. After decades of efforts of one generation, we have independently developed three generations of various models of camouflage nets. Technology has reached the world leading level. Among them, 65 camouflage net, 84 camouflage net, 8 1 camouflage net, 87 camouflage net and 95 camouflage net are representative.
65 camouflage net is the first generation of optical camouflage net developed and finalized in China, which can resist both visible light reconnaissance and near infrared reconnaissance. The base material is PVC plastic monofilament, and there are two different camouflage patterns on both sides of the camouflage net, which can adapt to the different backgrounds of two or three seasons in most parts of China.
Camouflage net is a kind of leaf net with high ultraviolet reflection in snow, which is used to camouflage weapons and military facilities under the snow background. Snow is a special background, because it has a high reflectivity to ultraviolet rays (which ordinary white pigment paints can't reach). 84 camouflage net successfully uses the micro-bubble coating with snowflake structure, which realizes high ultraviolet reflection on the surface of camouflage net and is compatible with visible light and near infrared reflection characteristics.
8 1 camouflage net is the second generation anti-radar camouflage net developed and finalized in China. It uses the principle of scattering. After the metal wire is woven into the fabric, the incident radar wave scatters evenly in all directions through cutting and stretching, and the radar wave scattering characteristics on the surface of the camouflage net tend to be consistent with the application background through secondary transmission attenuation, thus realizing the radar protection performance of the camouflage net. 8 1 Camouflage net adopts camouflage points coated with camouflage paint, which can prevent both visible light and near-infrared reconnaissance. 8 1 camouflage net also has its immature technology. It only shapes the woodland camouflage net, and its protective belt is mainly in centimeter band.
87 camouflage net is mainly developed on the basis of 8 1 camouflage net. The problem of exposed metal wire and imperfect process in metal wire spinning is solved by adding short stainless steel fiber into the textile thread of fabric to replace the metal wire of 8 1 camouflage net. 87 camouflage net also improved the cut flower form of the net surface, widened the radar-proof frequency band from centimeter wave to millimeter wave, and strengthened the coating fastness of the camouflage net surface. Several models of forest mosaic camouflage net, desert camouflage leaf camouflage net, grassland type and snow type were developed, and the supporting FRP equipment was designed.
95 camouflage net is the third generation camouflage net developed and finalized in China. With the wide application of thermal detection equipment in modern battlefield, modern camouflage net must solve the problem of preventing middle and far infrared reconnaissance. 95 camouflage net consists of camouflage net and heat insulation layer. The military camouflage net is made of different cut flowers and different decorative materials on the skeleton net. These different forms of flower arrangement decorative materials and processed PVC tufts have different emissivity and thermal conductivity. The thermal insulation layer is made of thermal insulation cloth with high reflective coating on the inner surface and high and low emissivity coating on the outer surface, which can effectively shield and distort the thermal image of the target.
