Description
Technical Field
The utility model relates to a camouflage net, especially a multispectral camouflage net.
Background
Camouflage nets are stealth fabrics used by military to cover weaponry or fixed targets for low detectability. The camouflage principle is that the camouflage net is utilized to form an arched or planar barrier to weaken the planar reflection of the equipment and eliminate the appearance characteristics of the equipment, so that the difficulty in reconnaissance and identification of the enemy is increased. The modern military camouflage net also has the following characteristics: not only can resist visible light reconnaissance, but also can resist thermal infrared reconnaissance, radar reconnaissance and the like; the optical properties of the color and the camouflage spots of the mesh surface, the thermal infrared radiation property of the mesh surface and the scattering property of radar waves can meet the requirements of different target environment backgrounds; the modern camouflage net also has the advantages of light material, good coating firmness, convenient splicing and multiple purposes. Some developed countries have given a high degree of attention to the study of camouflage nets. The multi-band camouflage net (BMS-ULCAS) of the Brauda corporation in Sweden adopts a novel absorption principle, achieves the aim of multi-spectrum stealth compatibility through a multifunctional coating technology, and has the performances of optical prevention, near infrared prevention and radar detection prevention. The ultra lightweight camouflage net system (ULCANS) shape in the united states comprises hexagonal and diamond shaped sections interconnected by lacing loops and a basic design comprising tough polymeric anti-snag fibers with cut patterns that have good radar scatter and thermal imaging resistance. In addition, the standard camouflage net structure developed and produced by German OGUS company and the MKT-3JI standard camouflage net of Russia have very good camouflage effect. Wherein the optical confrontation spectrum of the fourth generation camouflage net technology in the army is 0.32-1.2 μm. The development of camouflage nets in China begins in the 60 s of the 20 th century, and various models of camouflage nets such as 65-type camouflage nets, 72-type camouflage nets and 95-type camouflage nets are developed through decades of development.
The 65-type camouflage net is the first anti-optical reconnaissance camouflage net developed and shaped in China, and can resist against the reconnaissance of visible light, near infrared photography and infrared night vision devices. Camouflage spot patterns are arranged on the front side and the back side of the camouflage net, and the camouflage spots have various colors such as light green, medium green, dark green, hay, sandy soil, black brown, white and the like.
The 72 type camouflage net is an improved 65 type camouflage net, and the optical reconnaissance performance and the camouflage speckle pattern of the net are basically the same as those of the 65 type camouflage net except that the unit mass of the net surface is lighter than that of the 65 type camouflage net.
The 87 camouflage net is a technical improvement of the 81 camouflage net, and stainless steel short fibers are blended in the knitting lines of the fabric, so that the problem of imperfect metal wire spinning process is solved, and the random orientation in the stainless steel short fibers is more reasonable;
the 95 camouflage net is a third generation camouflage net developed in China, consists of a camouflage net surface and a thermal isolation layer, can effectively solve the problem of preventing middle and far infrared reconnaissance, and has the characteristics of optical reconnaissance prevention and radar prevention. The common problems of various models of camouflage nets such as 65 type, 72 type and 95 type are that: the camouflage wave band is not wide enough to meet the thermal infrared performance, the radar has narrow wave-absorbing width (4-26 GHz), weak absorption strength (average attenuation less than 6 dB) and high surface density which is generally more than 500g/m 2 The overall camouflage performance is low, and the use is inconvenient. Therefore, the high-performance and light camouflage net is urgently designed, and the improvement of the battle efficiency of enemies of our army is facilitated.
