Description

  The present invention relates to a concealment device that conceals an object or person to be concealed, such as a person, a building, a material, or a vehicle, by camouflaging it.

Several means for making an aircraft, a ship, a vehicle, a human and the like difficult to be recognized by enemy reconnaissance have been proposed.
For example, Patent Document 1 discloses that only a visible ray and a near infrared ray are obtained by fixing a part of a leaf-like fabric not containing a metal thin film layer having a camouflage colorant-containing resin layer to a mesh-like fabric having a metal thin film layer. In addition, a camouflaged structure having excellent camouflage performance against far infrared rays has been proposed.

  In the military field, it is extremely important to conceal the presence and position of friendly soldiers, supplies, vehicles, etc. from the enemy. For example, on the battlefield, when enemy soldiers confront each other, if they can delay the timing when the enemy notices their presence even after 1 second due to concealment, the probability that the soldier will attack the enemy first and not lose their lives increases. .

  In order to conceal the presence and position of friendly soldiers, supplies, vehicles, etc. from the enemy, it is first necessary that the enemy is not visually recognized. In other words, it is necessary to disguise the “look” so as not to be seen as soldiers, supplies, vehicles, etc., so that enemy soldiers think that they are not soldiers, supplies, vehicles, etc. As a means of such camouflage, since there are many places where the battlefield is covered with plants, things such as covering with a pattern of plants and attaching a model of plants to the surface have been widely used in the past. . In addition, by attaching plants growing on the battlefield to clothes and helmets, it has been made difficult to find them from the enemy.

  However, human ability to analyze images is extremely high in the first place. For example, in the close battle on the battlefield, impersonation by artificial objects or simply attached plants is easily detected, which is not very useful. In recent years, the resolution of aerial photographs and satellite photographs has increased, and as a result of advances in image analysis technology using computers, plants that naturally grow by analyzing images of aerial photographs and satellite photographs. It has also become possible to detect differences between artifacts for impersonation and unnaturally attached plants.

  In view of the above circumstances, an object of the present invention is to provide a better means for hiding ally soldiers, supplies, vehicles, and the like for image analysis such as visual inspection of an enemy and aerial photographs.

The present invention has been conceived in view of the above object,
A wall that has an external surface shape imitating the external shape of a rock that has not been processed, and that conceals the top and side surfaces of objects or people to be concealed;
A natural lava piece fixed on the outer surface of the wall is provided (first embodiment).

In the first embodiment described above,
Wavelengths included in a specific wavelength band disposed inside the natural lava pieces so as to cover the upper and side surfaces of the object or person to be concealed disposed in the hollow portion formed inside the wall. A configuration including an anti-radar shielding layer that absorbs electromagnetic waves or reflects the electromagnetic waves in a direction different from that of the electromagnetic wave transmission source may be employed (second embodiment).

In the above first or second embodiment,
A configuration may be employed that includes imaging means for imaging a landscape outside the wall and outputting image data obtained by the imaging to the inside of the wall (third embodiment).

In any one of the first to third embodiments,
The wall shields the vehicle;
A first fastener fixed on an outer surface of the vehicle;
A structure provided on the inner side surface of the wall and provided with a second engagement device that is detachably engaged with the first engagement device may be employed (fourth embodiment).

In the above first or second embodiment,
A configuration may be employed that includes fixing means for fixing the wall to the ground by projecting from the wall and being driven into the ground in a state where the wall is disposed on the ground. (Fifth embodiment)

In the above first or second embodiment,
A structure comprising a fixing means for fixing the wall to the ground by being fixed to the ground by a nail-like member protruding from the wall and driven into the ground in a state where the wall is disposed on the ground. It may be adopted (sixth embodiment).

In any one of the first to sixth embodiments,
A configuration including a pseudo plant that is an artificial object having an appearance imitating the appearance of a natural plant attached to the natural lava piece may be employed (seventh embodiment).

In any of the first to seventh embodiments,
A structure in which at least a part of the material of the wall is at least one of ABS resin and duralumin may be employed (eighth embodiment).

  According to said 1st embodiment, a plant is made to grow on the natural lava piece arrange | positioned on the outer surface of the wall which has an outer surface shape like a rock, and a person, a building, supplies, a vehicle, etc. are covered with the wall. Therefore, when viewed from the outside, it looks the same as the natural rocks there since ancient times. At that time, even if the same plant that grows in the place where it is alive and grows on the surface of the wall, even animals do not notice the disguise. Therefore, it is difficult to find a concealment due to the camouflage even by human visual inspection or image processing analysis.

  Furthermore, although it is difficult to change the color etc. of an artificial object according to a change of a season, according to said 1st embodiment, the plant which grew in the natural lava piece changes to a season like a surrounding plant. Since the color, shape, etc. are changed accordingly, there is no inconvenience that, for example, only the camouflage is conspicuous as a summer plant color in the winter scenery.

  Natural lava has a large number of holes of various shapes and diameters, so that it has a high water content and a long water retention time, and a wide variety of organisms can live in the natural lava. In other words, natural lava is an excellent material that is unmatched as a highly durable substrate that can grow plants.

  In addition, according to the second embodiment, since the anti-radar blocking layer exists, even if the enemy tries to find a concealment using a radar that uses reflection of electromagnetic waves, The discovery of the concealment by can be avoided.

  In addition, according to the third embodiment, for example, even when the vehicle, the soldier, or the like is almost completely covered with the shielding tool, the driver, the soldier, etc. of the vehicle is externally captured by the imaging means. You can check the scenery inside the shield. Therefore, it is possible to move the vehicle while being covered by the shielding tool, or to advance a soldier or the like.

  Moreover, according to said 4th embodiment, the operation | work which attaches a shield to a vehicle or removes a shield from a vehicle can be easily performed by the 1st engaging tool and 2nd presence which are attachments. .

  Moreover, according to said 5th embodiment, by providing the fixing means which fixes a wall to the ground, it prevents that the shielding tool which covers materials etc. moves easily by a wind etc. Thus, for example, supplies can be kept hidden from the enemy for a relatively long time on the battlefield.

  Further, according to the sixth embodiment, since the wall can be fixed to the ground using a nail-like member such as a so-called picket, the same effect as in the fifth embodiment can be obtained. Can do.

  Moreover, according to said 7th embodiment, since the artificial plant which is an artificial object has previously adhered to the natural lava wall, for example, until the natural plant grows, performing the camouflage to the extent of the prior art Can do.

  Moreover, according to said 8th embodiment, since ABS resin or duralumin is used for at least one part of the wall, many advantages, such as intensity | strength, workability, and lightness, can be enjoyed.

(Embodiment 1)
Hereinafter, an embodiment which is a specific example of the present invention will be described with reference to the drawings. FIG. 1 is a diagram schematically illustrating a case where the shield 1 according to the present embodiment is attached to a vehicle C. In FIG. 1, a state where almost half of the front side of the shielding tool 1 is cut out is shown so that the positional relationship between the vehicle C and the shielding tool 1 becomes clear.

  The shield 1 includes a wall 11 that covers the upper surface and side surfaces of the vehicle C, a natural lava piece 12 fixed on the outer surface of the wall 11, and an anti-radar shielding layer 13 (illustrated) disposed inside the natural lava piece 12. (Not shown), a CCD camera 14 (not shown) that captures the scenery outside the wall 11, a first anchor 15 (not shown) fixed on the outer surface of the vehicle C, and the inner surface of the wall 11 And a second engaging tool 16 provided on the top.

  The wall 11 is made of, for example, ABS resin. ABC resin is a strong thermoplastic resin obtained by polymerizing acrylonitrile, butadiene, and styrene. It has all the advantages of polystyrene and has excellent heat resistance, impact resistance, and dimensional stability. It is used in cabinets for household appliances such as TVs, interior parts such as automobile instrument panels, housings for office equipment, helmets, and travel bags. Further, since the specific gravity falls within the range of 1.05 to 1.07, it is relatively light and suitable for mounting on the vehicle C or the like. This is because the vehicle C moves in a state where the shield 1 is attached, and therefore it is preferable that the overall weight is as small as possible.

  Moreover, the wall 11 is provided with the external surface shape which imitated the external surface shape of the rock which is not processed, ie, the rock which exists naturally in a battlefield. More specifically, for example, the wall 11 covers the object to be shielded from the upper side to the side surface, has an opening on the lower side, and has a certain shape that forms a hollow space defined by the wall 11 and the ground. ing. And a to-be-shielded object is arrange | positioned in the said hollow space. By maintaining such a shape, the wall 11 can become familiar with the surrounding scenery and hide the object to be shielded from the eyes of the enemy. However, the opening of the lower side of the wall 11 does not limit the present invention.

  Further, since the wall 11 covers the vehicle C as shown in FIG. 1, for example, the length of the vehicle C in the longitudinal direction is about 4 meters, and the length in the direction perpendicular to the longitudinal direction and parallel to the ground is long. The height is about 2.5 meters and the height is about 2 meters. Furthermore, the thickness of the wall 11 is about 3 centimeters, for example. However, the wall 11 having these sizes does not limit the present invention.

  The natural lava pieces 12 are fixed on the outer surface of the wall 11 by, for example, an adhesive, and the gaps of relatively large natural lava pieces are filled with relatively small natural lava pieces so that the gaps are not visible when viewed from the outside. It has become. Therefore, the wall 11 of the shield 1 is not visually recognized from the outside.

  When almost no plants grow on the battlefield, the shielded object is concealed in a state where the natural lava fragments 12 are exposed to the outside, that is, as shown in FIG. Therefore, it is desirable that the natural lava pieces 12 are the same as the natural lava scattered on the battlefield, and if it is difficult to obtain the same natural lava on the battlefield, a natural lava that looks similar to that is used. It is desirable. In addition, when natural lava is not often seen on the battlefield, it is desirable to use natural lava that looks similar to rocks other than natural lava that are scattered on the battlefield.

  However, in many cases, plants are growing on the battlefield. In order to conceal the object to be shielded on such a battlefield, it is desirable that the plants growing on the battlefield grow on the natural lava pieces 12. Therefore, first, moss and the like are planted in the holes that the natural lava pieces 12 have, and then grass is planted to root them there. Natural lava provides an unparalleled good environment for plants to take root due to its porosity (the property of having a large number of pores of various particle sizes and grain shapes).

  FIG. 2 shows the shield 1 in such a state that its outer surface is covered with moss and grass. Concealment by the shield 1 in a state where mosses and grass are overgrown becomes extremely difficult to detect by visual analysis and image analysis of at least a photograph taken with visible light. This is because the appearance is almost the same as the surrounding nature.

  The anti-radar shielding layer 13 absorbs electromagnetic waves having a wavelength included in a specific wavelength band (γ rays, X-rays, ultraviolet rays, visible rays, infrared rays, radio waves, etc.), or a direction in which the electromagnetic waves are different from the source of the electromagnetic waves. Reflect on. Here, the electromagnetic wave having a wavelength included in a specific wavelength band is an electromagnetic wave having a wavelength that passes through the natural lava fragments 12 and the wall 11.

  In general, the radar detects an object. The radar sends a radio wave, the radio wave hits the object, an induced current is generated, a reflected wave is generated by the radio wave generated from the induced current, the radar picks up the reflected wave, and is transmitted. And the reception time difference, the distance from the object, and the general direction can be determined from the radiation characteristics of the antenna. In addition, a radio wave is a thing with a wavelength more than infrared rays among electromagnetic waves.

  In order not to be detected by the radar as described above, either means of reflecting the radio wave in a direction other than the direction from which the radio wave came or absorbing the radio wave is used. In order to reflect a radio wave in a direction other than the direction from which the radio wave comes, a shape control technique is generally used. As an example of the shape control technique, the radar shielding layer 13 is a thin metal plate that covers a vehicle C existing inside the wall 11 and is configured by a plane inclined obliquely from the direction in which radio waves are transmitted. .

  That is, if the anti-radar shielding layer 13 does not exist, most of the radio wave transmitted from the radar passes through the natural lava pieces 12 and the walls 11 and is reflected by the vehicle C, and again passes through the walls 11 and the natural lava pieces 12. Pass through and part of it goes in the direction of the radar. As a result, the vehicle C is detected by the radar. However, the shield 1 is provided with an anti-radar shielding layer 13, and the anti-radar shielding layer 13 reflects radio waves that have passed through the natural lava fragments 12 and the walls 11 in an oblique direction, and the radio waves are directed in the direction of the radar. Therefore, the vehicle C is not detected by the radar.

  Alternatively, in order to absorb radio waves, radio wave absorber technology is generally used. When the radio wave absorber technology is used, the radar shielding layer 13 is a radio wave absorbing material having a predetermined thickness fixed on the inner surface of the wall 11. Radio wave absorbing materials are roughly divided into three types: conductive radio wave absorbing materials, dielectric radio wave absorbing materials, and magnetic radio wave absorbing materials. The anti-radar shielding layer 13 according to the present embodiment is, for example, rubber sheet ferrite that is one of magnetic wave absorbing materials.

  The conductive radio wave absorbing material absorbs current generated by radio waves due to resistance inside the material. Excellent electromagnetic wave absorbers have been put to practical use by conductive fiber fabrics. In addition, dielectric electromagnetic wave absorbing materials use dielectric loss due to molecular polarization reaction, but large loss cannot be expected with a single dielectric, so carbon powder etc. is mixed with dielectric such as rubber, urethane foam, polystyrene foam etc. As a result, a device having a larger apparent dielectric loss has been developed. Furthermore, the magnetic wave absorbing material absorbs radio waves due to the magnetic loss of the magnetic material. Iron, nickel, and ferrite can be used to absorb radio waves, but the disadvantage is that they become heavier.

  In addition, when none of the conventional radio wave absorbing materials sufficiently absorbs electromagnetic waves that pass through the natural lava pieces 12, a new electromagnetic wave absorbing material that sufficiently absorbs electromagnetic waves that pass through the natural lava pieces 12 is adopted for the radar shielding layer 13. Will be.

  In the present invention, the radar shielding layer 13 having both the shape control technique and the radio wave absorber technique described above may be employed.

  The CCD camera 14 is necessary because the vehicle C is almost completely covered by the shield 1 as shown in FIG. That is, in order for the vehicle C to move in a state in which the vehicle C is almost completely covered by the shield 1, it is necessary for the driver to grasp the outside scenery. The CCD camera 14 employs a CCD (Charge Coupled Device), which is a semiconductor light receiving element (charge coupled device) that converts light into an electrical signal as an imaging element.

  In the present embodiment, the CCD camera 14 images a landscape outside the wall 11 and outputs image data obtained by the imaging to the inside of the wall 11 through a communication line (wired) as digital data. A configuration that outputs an analog signal indicating an image captured by the CCD camera 14 may be employed. Further, instead of the CCD camera 14, an image pickup apparatus using another type of image pickup device such as a CMOS (Complementary Metal Oxide Semiconductor) may be employed. Furthermore, instead of outputting these data or signals via a communication line (wired), a configuration of outputting them wirelessly (radio waves) may be employed. However, since radio is easy to detect by the enemy, it is necessary to take another measure for it.

  The CCD camera 14 is embedded in a hole penetrating the wall 11 with its imaging surface exposed to the outside. A communication line connected to the CCD camera 14 comes out of the wall 11 and is connected to a display arranged in the vehicle C. The driver of the vehicle C can perform driving or the like while viewing an image showing an external landscape displayed on the display.

  The first anchor 15 is a male anchor that is engaged and arranged on the outer surface of the vehicle C by, for example, screwing and extends outward. However, the above-described screw fastening and male type do not limit the present invention.

  The first engaging member 15 is, for example, a synthetic resin member composed of four rod-shaped bodies, and the length of the rod-shaped body in the longitudinal direction is about 15 centimeters.

  The second anchor 16 is a female anchor that is engaged and arranged on the inner surface of the wall 11 by, for example, screwing and extends inward. However, the above-described screw fastening and female type do not limit the present invention.

  The second engaging tool 16 is, for example, a synthetic resin member made of four rod-shaped bodies, and the length in the longitudinal direction of the rod state is about 15 centimeters.

  The male structure of the first engaging device 15, for example, a columnar protrusion, is engaged with a female structure of the second engaging device 16, for example, a recess provided at one end of the columnar shape. Worn. As shown in FIG. 2, the vehicle C is covered with the shield 1 by engaging each of the four first engaging members 15 and the second engaging member 16. However, in this state, the skirt portion of the shield 1 is not in contact with the ground, so that the vehicle C can move while checking the surrounding scenery with the CCD camera 14.

  An example of a method of using the shielding tool having the above configuration will be described below.

  The vehicle C on which the shield 1 is mounted is stopped at the friendly side of the battlefield. In general, the means by which the enemy finds the vehicle C is by visual observation, by reflection of radio waves transmitted from the radar, or by infrared rays due to heat generated by the vehicle C or a human (such as a driver or a soldier on board). Either detect or not.

  When visually observed, the shield 1 appears to be assimilated with the surrounding landscape by the shape of the wall 11 and natural lava pieces 12 fixed on the outer surface of the wall 11 and natural plants growing on the natural lava pieces 12. It is extremely difficult for the enemy to find the vehicle C, the driver, etc.

  Further, the radio wave transmitted from the radar is reflected by the anti-radar shielding layer 13 in a direction different from the radar or absorbed by the anti-radar shielding layer 13, so that the vehicle C, the driver, etc. are detected by the radar. It is also unlikely that

Further, the heat generated by the vehicle C or the human being in the shield 1 is once absorbed by the natural lava pieces 12 and then released to the outside of the shield 1 over time. Therefore, the thermal sensor for detecting infrared rays is not very useful for the purpose of finding the vehicle C or the driver in the shield 1.
In this way, the vehicle C, the driver, etc. concealed in the shield 1 are difficult to be detected by the enemy, so it is possible to attack the enemy in case of emergency or move to the friendly base through the enemy team It becomes.

(Embodiment 2)
Hereinafter, another embodiment (Embodiment 2) according to the present invention will be described with reference to the drawings. In the following description, the second embodiment will be described focusing on the differences from the first embodiment described above.

  FIG. 3 is a diagram showing an outline when the shield 2 according to the present embodiment is used for a so-called material B. As shown in FIG. In FIG. 3, a state where almost half of the front side of the shielding tool 2 is cut out is shown so that the positional relationship between the material B and the shielding tool 2 becomes clear.

  The shield 2 is disposed inside the natural lava piece 22, a wall 21 (not shown) that covers the top and side surfaces of the material B, a natural lava piece 22 (not shown) that is fixed on the outer surface of the wall 21. And a radar shielding layer 23 (not shown) and fixing means (not shown) for fixing the wall 21 to the ground.

  The fixing means is constituted by a nail-like member protruding from the wall 21 and driven into the ground in a state where the wall 21 is disposed on the ground.

  The nail-like member is integrally formed with the wall 21, for example. Therefore, for example, the material of the nail-like member is ABS resin like the wall 21.

  Further, for example, the length of the nail-like member in the longitudinal direction is about 10 centimeters, and the nail-like members are provided at intervals of 50 centimeters on a substantially circumference constituting the lower end portion of the wall 21. These sizes do not limit the present invention.

  The nail-like member may not be integrally formed with the wall 21. Therefore, a fixing means for fixing the wall 21 to the ground by protruding from the wall 21 and being fixed to the ground by a nail-like member driven into the ground in a state where the wall 21 is disposed on the ground. May be provided. In this case, a portion to be fixed near the bottom of the wall 21 is provided to be pressed downward by any portion of the nail-like member. In this case, the nail-like member is made of stainless steel, for example.

  The fixed part is, for example, a rectangular member extending in a direction parallel to the ground from the wall 21, and a plurality of the fixed parts are provided at intervals of 50 centimeters on the substantially circumference constituting the lower end part of the wall 21. It has been. And the hole for driving the part except the head of the above-mentioned nail-like member is provided in the center vicinity of the said to-be-fixed part, respectively. In addition, the shape of a to-be-fixed part and this are not restricted, A thing with various shapes can be employ | adopted in the shield 2. FIG.

  In addition, when the material B is covered with the plant covering 2 covered with plants, the state shown in FIG. 4 is obtained. Since the shield 2 is fixed to the ground by the fixing means described above, the shield 2 is not moved by wind or the like.

  As described above in the first embodiment, the shielding tool 2 configured as described above conceals an object to be shielded arranged in the shielding tool 2 from any enemy detection means as invalid. can do.

(Embodiment 3)
Hereinafter, an embodiment (Embodiment 3) according to the present invention, which is different from Embodiments 1 and 2 described above, will be described with reference to the drawings. In the following description, parts different from those of the first and second embodiments will be mainly described.

  FIG. 5 is a diagram showing an outline when the shield 3 according to the present embodiment is used for a so-called soldier S. FIG. FIG. 5 shows a state in which almost half of the front side of the shield 3 is cut out so that the positional relationship between the soldier S and the shield 3 becomes clear.

  The shield 3 includes a wall 31 (not shown) that covers the upper and side surfaces of the material B, a natural lava piece 32 (not shown) fixed on the outer surface of the wall 31, and a radar shielding layer 33 (not shown). With. The anti-radar shielding layer 33 is necessary because a weapon possessed by the soldier S or a metal contained in an object worn by the soldier S may reflect radio waves emitted by the radar.

  In addition, the shielding tool 3 has the opening part O for the soldier S to shoot a gun in the side part. However, this does not limit the present invention.

  The soldier S can wait for an enemy attack in the state shown in FIG. In this state, the soldier S may advance forward. Therefore, it is desirable that the shield 3 has a size corresponding to the physique of the soldier S and is as light as possible. In addition, when the soldier S is covered with the shield 2 overgrown with plants, the state shown in FIG. 6 is obtained.

  As described above with respect to the first and second embodiments, the shield 3 configured as described above invalidates all enemy detection means. Therefore, the soldier can reduce the possibility of being known to the enemy by its presence and its position. On the other hand, the soldier S can also shoot a gun toward the enemy from an opening O provided in one side surface portion of the shield 3.

(Modification)
The embodiments described above can be variously modified within the scope of the technical idea of the present invention. Examples of these modifications are shown below.

  The numerical values representing the shape, material, length, etc. used in the description of the shielding tools 1, 2, and 3 are merely examples, and any other shape, material, and numerical value may be employed in the shielding device according to the present invention. For example, the wall 11 is made of ABS resin, but other materials such as duralumin may be used as the material.

  In addition, the natural lava pieces 12, 22, and 32 are fixed on the outer surface of the wall 11 by an adhesive, for example, but may be fixed on the outer surface of the wall 11 by any other method.

  Moreover, the structure which attaches the pseudo plant which is the artificial object which has the external appearance imitating the external appearance of a natural plant may be employ | adopted for the natural lava pieces 12, 22, and 32. In that case, in the case where the plant is thick in the surroundings, the shields 1, 2, and 3 can be camouflaged as a natural object to some extent by the pseudo plant until the natural plant grows thick.

  The radar shielding layers 13, 23, 33 are provided inside the walls 11, 21, 31. However, as long as they are arranged inside the natural lava pieces 12, 22, 32, they are provided at any position. It may be done. Therefore, for example, when the electromagnetic wave emitted from the radar has a wavelength that does not pass through the walls 11, 21, and 31, the walls 11, 21, and 31 are not detected by the radar. , 21 and 31 and the natural lava pieces 12, 22, and 32 are desirable.

  In addition, as an example of the shape control technique described above, the radar shielding layers 13, 23, and 33 are metal thin plates configured by planes inclined obliquely from the direction in which radio waves are transmitted. Any method or means may be used as long as it reflects the radio wave in a direction other than the direction from which the wave comes.

  In addition, as an example of the above-described radio wave absorption technology, the anti-radar shielding layers 13, 23, and 33 are layers having a predetermined thickness made of a radio wave absorption material, but most of the radio waves transmitted from the radar are used. Any other material may be used as long as it can absorb.

  Further, the engagement between the shielding tool 1 and the vehicle S by the first engaging tool 15 and the second engaging tool 16 may be replaced by any other means. For example, the male and female of the first engagement device 15 and the second engagement device 16 may be reversed, and a configuration is employed in which they have a structure that engages with each other without the sex. Also good.

  Moreover, the fixing means described above may be replaced by any other means for fixing the shield 2 to the ground.

  Moreover, the above-described barrier may cover any object or person other than the vehicle C, the material B, and the soldier S. For example, a helmet worn by the soldier S may be covered.

  Moreover, the usage method of the shielding tool concerning embodiment mentioned above is an example to the last, and a shielding tool may be used by what kind of other method. For example, when a hole is dug underground and a stockpile of goods is stored in the hole, the opening of the reserve hole may be shielded by the shielding tool according to the present invention. In that case, the shielded object becomes the stockpiling hole.

  In addition, the external appearance of the battlefield where the shielding tool concerning this invention is used is shown in FIG. The color of the landscape as shown in FIG. 7 changes according to the change in season of the battlefield. This is because the growing plant changes its color. According to the shield according to the present invention, since natural plants cover their surfaces, the color and the like of the surrounding plants change according to the change of seasons. For this reason, there is no risk that the camouflage becomes invalid as the season changes.

  As described above, according to the present invention, friendly soldiers, vehicles, weapons, supplies, etc. can be concealed from the enemy's exploration by visual observation, image processing, radar, thermal sensors, etc. on the battlefield. As a result, it is possible to reduce ally sacrifices and develop more effective tactics against the enemy.

  Also, military buildings such as ordinary stockpiles disturb the landscape and often destroy nature for its construction. In particular, in the case of a jungle where the battlefield is blessed with nature, the loss due to natural destruction caused by the construction of military equipment is large. On the other hand, according to the shield according to the present invention, it is possible not only to conceal military equipment from enemies, but also to reduce the degree of natural landscape disturbance and the degree of natural destruction.

  In the above description, it has been described that what surrounds the shield according to the present invention is a plant, but it goes without saying that organisms such as insects may live together with the plant. Such animal inhabitants can realize camouflages that are harder to detect.

  The shield according to the present invention is mass-produced because it is widely effective in hiding from enemies such as humans, buildings, supplies, and vehicles on the battlefield, and can be used in the manufacturing industry, the construction industry, and the like.
