在現代戰場上，有一種能讓坦克、直升機甚至軍事陣地“隱身”的裝備——偽裝網。它就像給武器裝備披上的“保護傘”，能大幅降低被敵方偵察發現的概率。根據我國軍標GJB 434定義，偽裝網是“具有裝飾材料的網狀結構物”，而如今的輕型偽裝網，更是憑借輕便、高效的特點，成為戰場偽裝的“主力軍”。

　　On the modern battlefield, there is a device that can make tanks, helicopters, and even military positions "invisible" - camouflage nets. It is like a "protective umbrella" draped over weapons and equipment, which can significantly reduce the probability of being detected by enemy reconnaissance. According to the definition of our national military standard GJB 434, camouflage nets are "mesh structures with decorative materials", and today's lightweight camouflage nets have become the "main force" of battlefield camouflage due to their lightweight and efficient characteristics.

　　一、偽裝網的分類

　　1、 Classification of camouflage nets

　　偽裝網主要依據兩個維度分類：

　　The camouflage network is mainly classified based on two dimensions:

　　1.根據我國軍標GJB 7927要求，按偽裝性能主要分為：I型，能與特定背景環境（如林地、沙漠）在顏色和光譜反射特性上高度匹配的偽裝網。II型：采用標準偽裝色系，在顏色和光譜反射特性上達到標準要求的偽裝網。

　　According to the requirements of our national military standard GJB 7927, camouflage nets are mainly divided into Type I, which can highly match the color and spectral reflection characteristics of specific background environments (such as forests and deserts). Type II: A camouflage net that uses a standard camouflage color scheme and meets the standard requirements in terms of color and spectral reflectance characteristics.

　　2.按防護偵察波段主要分為：

　　2. According to the protection reconnaissance band, it is mainly divided into:

　　（1）防光學偵察偽裝網，可以對抗肉眼和光學儀器；

　　(1) Anti optical reconnaissance camouflage net, capable of countering the naked eye and optical instruments;

　　（2）防中遠紅外偵察偽裝網，可以對抗熱成像儀；

　　(2) Anti mid to far infrared reconnaissance camouflage network, capable of countering thermal imagers;

　　（3）防雷達偵察偽裝網，可以對抗雷達波；

　　(3) Anti radar reconnaissance camouflage net, capable of countering radar waves;

　　（4）防多波段偵察偽裝網能同時對抗以上多種偵察手段，集光學、中遠紅外和雷達防護于一體，是當前發展的主要方向；

　　(4) The anti multi band reconnaissance camouflage network can simultaneously counter multiple reconnaissance methods, integrating optical, mid infrared, and radar protection, and is currently the main direction of development;

　　（5）其他特殊用途偽裝網，其中，輕型偽裝網憑借其減輕重量、縮短偽裝作業時間的優勢，顯著提升了部隊的機動性和快速反應能力，因此“輕型化、便攜化”同樣是偽裝網發展的重要趨勢。

　　(5) Other special purpose camouflage nets, among which lightweight camouflage nets have significantly improved the mobility and rapid response capabilities of troops due to their advantages of reducing weight and shortening camouflage operation time. Therefore, "lightweight and portable" are also important trends in the development of camouflage nets.

　　二、輕型偽裝網的發展歷程（以美軍為例）第二次世界大戰時期，制式偽裝網得到應用，但功能單一，主要對抗可見光偵察，材料多為棉麻。隨著偵察技術覆蓋光學、紅外、雷達的全波段和紡織新材料的涌現，偽裝網的材料、性能和原理發生了革命性變化。現代輕型偽裝遮蔽系統(LCSS - 1970年代)是模塊化設計，具備防可見光、近紅外和雷達偵察能力，提供林地、沙漠、雪地等多種環境配色，并有雷達散射型和雷達透射型之分，以適應不同裝備。美國陸軍用FM20-3型LCSS超輕型偽裝網系統(ULCANS - 1990年代末):專為提升陸航直升機隱蔽性設計，重量比LCSS減輕約26%。其關鍵突破在于顯著提升了中遠紅外（達2.5μm）防護能力，熱傳輸減少42%，同時保持光學和雷達隱身性能。采用模塊化設計，易于部署。美軍用超輕型偽裝網絡系統（ULCANS）超輕型偽裝網系統增強版(ULCANS Increment I - 2018年起)是對ULCANS的重大升級，最大創新在于單面偽裝網正反兩面具備沙漠/城鎮、雪地/高山等不同的環境偽裝能力，適應性更強。采用極輕量化設計（約165g/m），無切花結構不易勾掛，無需支撐桿，便于修補

　　2、 The development process of lightweight camouflage nets (taking the US military as an example) During World War II, standard camouflage nets were applied, but their functions were single, mainly to resist visible light reconnaissance, and the materials were mostly cotton and linen. With the emergence of reconnaissance technology covering the entire spectrum of optics, infrared, and radar, as well as new textile materials, the materials, performance, and principles of camouflage nets have undergone revolutionary changes. The Modern Lightweight Camry and Sheltering System (LCSS -1970s) is a modular design that provides protection against visible light, near-infrared, and radar reconnaissance capabilities. It offers a variety of environmental colors such as forests, deserts, and snow, and is available in radar scattering and transmission types to accommodate different equipment. The US Army uses the FM20-3 LCSS Ultra Light Camouflage Network System (ULCANS - late 1990s): specifically designed to enhance the concealment of land and air helicopters, with a weight reduction of approximately 26% compared to LCSS. The key breakthrough lies in significantly improving the mid to far infrared (up to 2.5 μ m) protection capability, reducing heat transfer by 42%, while maintaining optical and radar stealth performance. Adopting modular design, easy to deploy. The US military's Ultra Light Camouflage Network System (ULCANS) Ultra Light Camouflage Network System Increment I (since 2018) is a major upgrade to ULCANS. The biggest innovation is that the single-sided camouflage network has the ability to camouflage different environments such as deserts/towns, snow/mountains on both sides, with stronger adaptability. Adopting an extremely lightweight design (about 165g/m), there is no cut flower structure that is difficult to hook, and no need for support rods, making it easy to repair

　　三、輕型偽裝網的結構與材料（以美軍系統為例）雖然不同系統結構各異，但核心組件通常包括：

　　3、 The structure and materials of lightweight camouflage nets (taking the US military system as an example) may vary depending on the system structure, but the core components typically include:

　　1.偽裝屏：核心部分由聚酯網等網狀基底和附著其上的切花迷彩布、無切花聚酯層等偽裝材料構成，提供視覺和光譜偽裝。雷達防護型通常混入不銹鋼等金屬纖維來散射雷達波。

　　1. Disguise screen: The core part is composed of a mesh substrate such as polyester mesh and camouflage materials such as cut flower camouflage cloth and polyester layer without cut flowers attached to it, providing visual and spectral camouflage. Radar protection type is usually mixed with metal fibers such as stainless steel to scatter radar waves.

　　2.支撐系統：支撐桿(LCSS/ULCANS)：用于撐起偽裝屏。錨樁：將偽裝網固定在地面。連接件/系緊帶：連接多塊偽裝屏或固定到支撐桿。形狀干擾器(ULCANS)：增加外形不規則性，增強偽裝效果，并在大風中穩定偽裝網。

　　2. Support system: Support rods (LCSS/ULCANS): used to support the camouflage screen. Anchor post: Fix the camouflage net on the ground. Connecting piece/tie strap: Connect multiple camouflage screens or fix them to support rods. ULCANS shape disruptor: increases the irregularity of the appearance, enhances the camouflage effect, and stabilizes the camouflage net in strong winds.

　　3.運輸與儲存：專用的運輸箱用于包裝和運輸偽裝屏及支撐組件。4.維修包：包含備用偽裝布、縫紉線等修補材料和工具，用于戰場快速修復。輕型偽裝網通過材料科學和結構設計的進步，在提供強大隱蔽保護的同時，最大限度地減輕了士兵負擔，提升了部隊在現代戰爭環境下的機動性和生存能力。它就像一件精心編織的“隱形斗篷”，在矛與盾的對抗中，持續守護著軍事目標的安全。

　　3. Transportation and Storage: Specialized transport boxes are used for packaging and transporting camouflage screens and supporting components. 4. Repair kit: includes spare camouflage cloth, sewing thread and other repair materials and tools for quick repair on the battlefield. Through advances in material science and structural design, lightweight camouflage nets provide powerful covert protection while minimizing the burden on soldiers and enhancing the mobility and survival capabilities of troops in modern warfare environments. It is like a carefully woven 'invisibility cloak', constantly guarding the safety of military targets in the confrontation of spears and shields.
