軍用偽裝網(wǎng)偽裝技術(shù)隱身原理

The stealth principle of military camouflage net camouflage technology

一、近紅外隱身原理：

1、 The principle of near-infrared stealth:

自行研制了具有近紅外隱身性能的迷彩涂料，偽裝網(wǎng)表面均用該種涂料涂覆，使偽裝網(wǎng)的綠色斑點(diǎn)與自然綠色植物達(dá)到了同譜同色，可對抗可見光、近紅外、多光譜成像偵察，也可對抗微光夜視偵察。

We have independently developed a camouflage coating with near-infrared stealth performance, and the surface of the camouflage net is coated with this coating, making the green spots of the camouflage net reach the same spectrum and color as natural green plants. It can resist visible light, near-infrared, multispectral imaging reconnaissance, and also resist low light night vision reconnaissance.

二、熱紅外隱身原理：

2、 The principle of thermal infrared stealth:

①法向熱疏導(dǎo)

① Normal heat conduction

與傳統(tǒng)偽裝網(wǎng)相比，該種偽裝網(wǎng)的通透率大大增加，有利于通風(fēng)降溫。偽裝網(wǎng)形成的通透孔自然形成了法向熱疏導(dǎo)，而且偽裝網(wǎng)的針葉也是沿法向散開，使熱量迅速傳導(dǎo)到空氣中。這種形態(tài)形成了立體疏導(dǎo)效果，構(gòu)成了熱紅外隱身的主體。

Compared with traditional camouflage nets, this type of camouflage net has a significantly increased transparency, which is beneficial for ventilation and cooling. The transparent holes formed by the camouflage net naturally form normal heat dissipation, and the needles of the camouflage net also disperse along the normal direction, allowing heat to quickly transfer to the air. This form forms a three-dimensional guidance effect, forming the main body of thermal infrared stealth.

②熱屏蔽與熱斑點(diǎn)分割

② Thermal shielding and hot spot segmentation

該種偽裝網(wǎng)內(nèi)部涂覆了熱反射層，將反射與屏蔽進(jìn)行了結(jié)合。同時，不同的偽裝網(wǎng)顏色斑點(diǎn)在疏密程度、表面發(fā)射率、內(nèi)部反射率上進(jìn)行了等級設(shè)計，使偽裝網(wǎng)表面形成熱斑點(diǎn)。

The camouflage net is coated with a thermal reflection layer inside, combining reflection and shielding. At the same time, different color spots on the camouflage net were graded in terms of density, surface emissivity, and internal reflectivity, resulting in the formation of hot spots on the surface of the camouflage net.

三、 雷達(dá)波隱身原理：

3、 The principle of radar wave stealth:

①散射原理

① Scattering principle

材料的針葉很密集，并且伸向各個方向，電磁波入射到針葉上，同時產(chǎn)生反射和透射，且多次反復(fù)。因此各個方向上都會有電磁波，這是散射原理。

The needle blades of the material are very dense and extend in all directions. Electromagnetic waves are incident on the needle blades, generating reflection and transmission, and repeated multiple times. Therefore, there will be electromagnetic waves in all directions, which is the principle of scattering.

②導(dǎo)線電流耗散原理

② Principle of wire current dissipation

針葉形多頻譜隱身網(wǎng)的針葉是一種電阻型纖維，它是導(dǎo)體，是很多很多導(dǎo)線天線，導(dǎo)線上又有恰當(dāng)大小的電阻。當(dāng)電磁波入射時，會在導(dǎo)電纖維上產(chǎn)生感應(yīng)電流。由于纖維有電阻，使感應(yīng)電流在流動和二次發(fā)射時消耗能量。這是導(dǎo)線電流耗散原理。

The needle shaped multispectral stealth net is a type of resistive fiber, which is a conductor and is used for many wire antennas, with appropriate resistance on the wires. When electromagnetic waves are incident, an induced current is generated on the conductive fibers. Due to the resistance of the fibers, the induced current consumes energy during flow and secondary emission. This is the principle of wire current dissipation.

③諧振吸收原理

③ Resonance absorption principle

根據(jù)應(yīng)用的條件或要求，改變針葉的長度可調(diào)節(jié)低頻電性能。如欲使低頻性能好，纖維長度要長一些。當(dāng)導(dǎo)線纖維的長度正好是波長的四分之一的倍數(shù)時，導(dǎo)線將產(chǎn)生諧振作用。由于導(dǎo)線有電阻，因而耗散能量會更多，這是諧振吸收原理。

According to the application conditions or requirements, changing the length of the needle can adjust the low-frequency electrical performance. To achieve good low-frequency performance, the fiber length should be longer. When the length of the wire fibers is exactly a quarter of the wavelength, the wire will produce resonance. Due to the resistance of the wire, more energy is dissipated, which is the principle of resonant absorption.

④相位抵消原理

④ Principle of phase cancellation

在任何一個電磁波入射方向上，針葉排列有前有后，有左有右，電磁波的反射又是多方向的。因而任何一點(diǎn)接收到的電磁波是來自多個反射點(diǎn)，是很多很多個反射信號的疊加，每個反射信號的相位各不相同，因而會產(chǎn)生相位抵消作用。

In any direction of electromagnetic wave incidence, the needle arrangement has front and back, left and right, and the reflection of electromagnetic waves is multi-directional. Therefore, the electromagnetic wave received at any point comes from multiple reflection points, which is a superposition of many, many reflection signals. The phase of each reflection signal is different, and thus phase cancellation occurs.
