Description

CAMOUFLAGE NET BASED ON SIGNATURE REDUCTION TECHNOLOGY}

The present invention relates to a camouflage net based on a signal reduction technology, and more particularly, to a camouflage net applicable to military facilities and equipment, such as operational naval ships and tanks, which have many multi-reflective structures and are difficult to apply the latest stealth technology. It is related to the radar cross section, infrared red signal, and visual signal reduction camouflage net, which are the main signal sources.

As is well known, the basic means of detecting the enemy is a radar, and when the energy wave is radiated to reach the target, the reflected wave is returned to the receiver, thereby determining the position of the opponent.

These radars have been used to detect the location of expensive military equipment, military facilities, and old ships, including self-propelled artillery, armored vehicles and tanks.

Therefore, in order to protect them from the enemy, it is important to safely separate from the enemy radar radio waves, and many related technologies have been developed.

For example, the radar reflecting area reduction technique is a method of changing and adjusting the shape of the structure reflecting the radar wave or applying the radar absorbing material, so in the case of a large structure such as a trap, the shape change after drying It is almost impossible, and when the radar absorbent material is applied in the form of paint coating, it is inconvenient to continuously repaint, and there is a problem of rapidly increasing the maintenance cost due to the very large work area.

As another example, there is a technique for reducing an infrared signal, which is a method of attaching an infrared signal monitoring device or the like is expensive, and when installed in a dry vessel, there are many difficulties in terms of weight and installation space.

As another example, there is a registered patent No. 075127 "camouflage fabric using an electroless plated fiber" registered by Samyang Chemical Industry Co., Ltd. In this case, the radar decay rate is as low as 3db, the center of the fineness and weaving method of the fiber As a result, it is difficult to increase or decrease the radar reflection area and infrared signal reduction ability as necessary, and a cost loss occurs because the net itself needs to be replaced during repair and repair.

The present invention was created in view of the above-described problems in the prior art, and in particular, it reduces the distance detected from enemy radar by reducing the radar reflection area so as to increase the main stealth performance of a marine military facility such as a ship. At the same time, it reduces the infrared signals emitted from the traps to improve the deception capability of allied ships against enemy missiles homing on the radar reflecting area or infrared signals, and to capture visual signals from traps such as high-speed vessels operating in enemy border areas. The main challenge is to provide a camouflage net based on signal reduction techniques that can be disturbed to make attacks difficult such as enemy gun fire.

The present invention provides a means for achieving the above object, in the camouflage net to protect the main military facilities, equipment from enemy surveillance system; An edge line forming an appearance of the camouflage net; A plurality of horizontal lines arranged along a horizontal direction of the border line and fixedly connected at regular intervals in a vertical direction of the border line; A vertical line arranged along the longitudinal direction of the border line and connected and fixed at a predetermined interval in the horizontal direction of the border line and being woven or knotted with the horizontal line to form an intersection point; A plurality of struts fixed to said intersection; Provides a camouflage net based on the signal reduction technology, characterized in that comprises a border line, horizontal line, vertical line, radar absorbing material applied to the support.

At this time, there is also a feature that is provided with a plurality of fixing rings in place of the rim line.

In addition, the border line is also characterized by being made of a polygon or a circle.

In addition, the cell formed by the intersection of the horizontal line and the vertical line is characterized by having a polygon or a circle.

In addition, the cross point is characterized in that the patch is further attached to the radar absorbing material.

In addition, the patch is characterized in that the polygon or circle.

In addition, the radar absorbing material to be applied to the camouflage net is characterized in that the material which absorbs, disturbs, and converts electromagnetic waves as any one selected from ferrite particles, nickel particles, graphite particles.

Furthermore, the radar absorbent material applied to the camouflage net is characterized in that it is a bat dye for reducing the reflectance of the infrared signal.

The camouflage net according to the present invention improves signal reduction capability in terms of stealth of military facilities and equipments such as old ships and tanks, and protects them from enemy attacks, and can be temporarily used according to the threat level and operational characteristics of the enemy without any structural changes. It is convenient to store and store, and has the advantage that it can be used for several ships, tanks and facilities in unit units or fleets.

In addition, the camouflage net according to the present invention can maintain the camouflage function for the visual information of the existing camouflage net, while reducing the radar reflection area and the infrared signal of the trap, thereby deciding the deception system for the enemy guided weapon possessed by the trap. The effect can be maximized, which greatly contributes to the survival of the ship, which is expected to result in very large lives and property loss.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

Figure 1 is an illustration of a gastrointestinal net based on the signal reduction technology according to the present invention, Figure 2 is an enlarged view of the main portion of Figure 1, Figure 3 is an illustration of a post used in the gastrointestinal net according to the present invention.

First, the present invention is composed mainly of a radar absorbing material and a net with support, and it is possible to increase or decrease the radar reflecting area and the infrared signal reduction ability as necessary, and the net itself. Easy maintenance is possible by simply replacing and repairing the parts without replacement.

Accordingly, the camouflage net based on the signal reduction technology according to the present invention can satisfy the requirements for Type III and Type IV of the US military standard MIL-PRF-53134, and at the same time MIL-PRF-53134 is applied to aircraft or land structures. While the scope of application is limited to the Ultra Lightweight Camaflage Net System, it has many features such as being exposed to actual enemy threats and also applicable to traps that are difficult to reduce stealth signals due to its structural characteristics.

As shown in Figures 1 to 3, the camouflage net based on the signal reduction technology according to the present invention is preferably made entangled in a woven form, the overall appearance may have a variety of forms, for example, such as triangle, square It can be formed into a polygon or a circle.

In addition, the plurality of cells 100 constituting the camouflage net may be formed in a polygon or a circle.

More specifically, the camouflage net according to the present invention includes an outline rim line 110, where "line" means "wire" of the material constituting the net.

As described above, the edge line 110 constitutes the outer appearance of the camouflage net of the present invention and may have various shapes.

In addition, a plurality of horizontal lines 120 are connected to and fixed to the border line 110 in the horizontal direction.

At this time, the horizontal line 120 is arranged in a plurality with a predetermined interval in the vertical direction.

In addition, a plurality of vertical lines 130 are fixed to the border line 110 to connect the border line 110 in a vertical direction to be orthogonal to the horizontal line 120.

In this case, the plurality of vertical lines 130 are also arranged at a predetermined interval, such as the horizontal line 120, in particular in the portion overlapping with the horizontal line 120 may be arranged in a form weaved, in some cases, By forming a knot by separate means can be configured to bind to each other.

In addition, the horizontal line 120 and the vertical line 130 may be bound in a knot shape when bound to the border line 110.

The horizontal line 120 and the vertical line 130 cross each other to form one cell 100.

Accordingly, an intersection point 140 is formed at a portion where the horizontal line 120 and the vertical line 130 intersect while overlapping, and the support 150 is connected and fixed to the intersection point 140.

The post 150 serves to lower the heat by increasing the radar wave absorption rate by maintaining a gap between the camouflage net and the hull when installing the camouflage net.

In addition, by fixing the fixing ring 160 in place, preferably four corners of the rim line 110 to guide the easy installation of the camouflage net and to maintain the appropriate tension.

On the other hand, the radar absorbing material is applied (or coated, embedded) to the horizontal line 120, the vertical line 130 and the support 150, including the edge line 110.

In this case, the radar absorbing material (RAM) is a material that satisfies US military standards, and absorbs radar energy to stay on the surface or to modify the radar reflection frequency to a frequency that cannot be read by the radar. It must be a material that can be made.

Such radar absorbing materials include, for example, ferrite particles which form a fixed magnetic field and block electromagnetic waves by thermally converting the electromagnetic waves while colliding with an electromagnetic wave having a variable magnetic field, and also conductive elements such as graphite and nickel. In the case of a conductive element, plating in the form of electroless plating is preferable.

In addition, a bat dye may be used to reduce the infrared signal reflected by the radar absorbing material.

The bat dye is a well-known dye disclosed in Korean Patent Publication No. 89-3173, and has a large number of intramolecular conjugated double bonds, which significantly lowers infrared reflectance in all regions of short wavelength and long wavelength. Therefore, the present invention is suitable for the camouflage net.

In particular, the material capable of reducing the infrared signal is preferably applied to the support (150).

On the other hand, the radar absorbent material may be attached in the form of a patch.

For example, as shown in Figures 1 to 3, by installing a patch 170 at each intersection 140, by covering the open cell 100 to reduce the radar or infrared signal while also having a light shielding effect. desirable.

In this case, the patch 170 is not limited to the circle as shown in the example, it is a matter of course that a variety of shapes, that is, polygonal shape is also possible.

In addition, the camouflage net according to the present invention, that is, the net including all the above-described configuration is more preferably painted in a camouflage color corresponding to the ambient color of the operation area to reduce the visual signal.

As described above, the present invention can solve the problem that it is difficult to deceive enemy attack due to lack of signal reduction capability in terms of stealth, such as old ships, tanks, and other military facilities, which are being built and operated, which are difficult to change in structure or shape. It is a very economical and efficient method compared to existing signal reduction techniques because it can be stored and used only when needed.

In addition, the application of the present invention can increase the concealment from the enemy surveillance system of major military installations, equipment, as well as the ability to avoid missiles tracking (targeting) the target according to the radar reflectance area or infrared signal. In addition, due to visual disturbances, it is possible to reduce the hit rate of the ship from the enemy's naked eye monitoring and gun fire.
