1、近红外隐身原理：

1. The principle of near-infrared stealth:

自行研制了具有近红外隐身性能的迷彩涂料。伪装网的表面均涂有这种涂料，使伪装网的绿色斑点与自然绿色植物达到了同谱同色，可对抗可见光、近红外、多光谱成像侦察，也可对抗微夜视侦察。

We have independently developed camouflage coatings with near-infrared stealth performance. The surface of the camouflage net is coated with this coating, which makes the green spots on the camouflage net reach the same spectrum and color as natural green plants. It can resist visible light, near-infrared, multispectral imaging reconnaissance, as well as micro night vision reconnaissance.

2、热红外隐身原理：

2. The principle of thermal infrared stealth:

①法向热疏导

① Normal heat conduction

与传统伪装网相比，该伪装网的通透率大大提高，有利于通风降温。伪装网形成的通透孔自然形成了法向热疏导，伪装网的针叶沿法向散开，使热量迅速传递到空气中。这种形式形成了三维分流效果，形成了热红外隐形的主体。

Compared with traditional camouflage nets, the transparency of this camouflage net is greatly improved, 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 disperse along the normal direction, allowing heat to quickly transfer to the air. This form forms a three-dimensional diversion effect, forming the main body of thermal infrared invisibility.

②热屏蔽与热斑点分割

② Thermal shielding and hot spot segmentation

该伪装网内部涂有热反射层，将反射与屏蔽相结合。同时，不同的伪装网络颜色斑点在密度、表面发射率、内部反射率等级设计，使伪装网络表面形成热点。

The camouflage net is coated with a thermal reflection layer inside, combining reflection and shielding. At the same time, different camouflage network color spots are designed in density, surface emissivity, and internal reflectivity levels, creating hotspots on the surface of the camouflage network.

3、雷达波隐身原理：

3. The principle of radar wave stealth:

①散射原理

① Scattering principle

材料的针叶非常密集，并向各个方向延伸，电磁波进入针叶，同时产生反射和透射，并多次重复。因此，各个方向都会有电磁波，这就是散射原理。

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

②导线电流耗散原理

② Principle of wire current dissipation

针叶多频谱隐身网的针叶是一种电阻纤维，它是一种导体，是许多导线天线，导线上有适当大小的电阻。当电磁波进入时，它会在导电纤维上产生感应电流。由于纤维有电阻，感应电流在流动和二次发射时消耗能量。这就是导线电流的耗散原理。

The needle of the multi spectral stealth net is a type of resistive fiber, which is a conductor and is used for many wire antennas. There is an appropriate amount of resistance on the wire. When electromagnetic waves enter, they generate induced currents on conductive fibers. Due to the resistance of fibers, induced currents consume energy during flow and secondary emission. This is the principle of dissipation of wire current.

③谐振吸收原理

③ Resonance absorption principle

根据应用条件或要求，改变针叶的长度可以调节低频电性能。如果想使低频性能好，纤维的长度应该要长一些。当导线纤维的长度只是波长的四分之一倍时，导线就会产生谐振。因为导线有电阻，所以会消耗更多的能量，这是谐振吸收的原理。

According to the application conditions or requirements, changing the length of the needle can adjust the low-frequency electrical performance. If you want good low-frequency performance, the length of the fiber should be longer. When the length of wire fibers is only a quarter of the wavelength, the wire will produce resonance. Because wires have resistance, they consume more energy, which is the principle of resonant absorption.

④相位抵消原理

④ Principle of phase cancellation

在任何电磁波的入射方向上，针叶有前有后，左有右，电磁波的反射是多方向的。因此，任何一点接收到的电磁波都来自多个反射点，这是许多反射信号的叠加。每个反射信号的相位不同，因此会产生相位抵消。

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