Description

Technical Field

[0001] This invention relates to the field of radar stealth technology, and in particular to an airbag-type multi-functional radar equipment protection system. Background Technology

[0002] To monitor the movements of surrounding military forces and prevent surprise attacks and violations of territory, airspace, and territorial waters, the deployment of main combat detection equipment such as radar command and control vehicles is of great significance. Our military has deployed multiple types of radar command and control vehicles and other main combat detection equipment in island and reef areas.

[0003] Currently, radar protection systems employ three methods: fiberglass radomes, concrete or steel structure shelters, and airbag-type shelters. Fiberglass radomes offer radar wave transmission but lack relocation capabilities. Concrete or steel structure shelters lack frequency-selective wave transmission, failing to meet the requirements for normal radar operation. Airbag-type shelters lack stealth capabilities. In operational status, radar vehicles have virtually no stealth protection, making their operational deployment easily detectable, marked, and targeted for wartime strikes. Furthermore, when radar and radar vehicles are relocated or deployed for missions, they are susceptible to environmental factors such as strong winds, heavy rain, and salt spray, which can reduce performance and even cause corrosion, affecting their lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide an airbag-type multi-functional radar equipment protection system. This airbag-type multi-functional radar equipment protection system has radar wave transmission and external shielding in the radar operating band, and has visible light, infrared and radar stealth functions. At the same time, it can provide a multi-functional protection system for the parking and working environment of radar vehicles, which is windproof, rainproof, temperature-controlled, dehumidified and desalinated.

[0012] According to one embodiment of the present invention, the airbag assembly further includes a stealth layer group disposed on the outside of the airbag arch and the airbag door to ensure radar wave transmission of the radar equipment and shield external radar waves, infrared rays and visible light.

[0013] According to one embodiment of the present invention, the stealth layer group includes a visible infrared coating, a stealth substrate, and a frequency-selective layer. The visible infrared coating is sequentially coated on one side surface of the stealth substrate, and the frequency-selective layer is connected to the other side surface of the stealth substrate away from the visible infrared coating to selectively transmit radar waves and reflect and shield radar out-of-band waves.

[0028] like Figures 1 to 5 As shown, Figure 1 A schematic diagram of an airbag-type multi-functional radar equipment protection system provided by the present invention is shown. Figure 2 A perspective view of an airbag-type multi-functional radar equipment protection system provided by the present invention is shown. Figure 3 A schematic diagram of the material of the airbag body 121 of an airbag-type multi-functional radar equipment protection system provided by the present invention is shown. Figure 4A schematic diagram of the internal circulation of an airbag-type multi-functional radar equipment protection system provided by the present invention is shown. Figure 5 The diagram shows a schematic of the stealth layer group 13 of an airbag-type multi-functional radar equipment protection system provided by the present invention.

[0029] The airbag-type multi-functional radar equipment protection system of this invention includes a controller, an airbag assembly 1, an environmental detection assembly, an environmental adjustment assembly 2, and a stealth cloak 3. The airbag assembly 1 forms a sealed space to accommodate the radar equipment. The airbag assembly 1 is electrically connected to the controller to automatically inflate and deflate. The environmental detection assembly includes an internal environmental detector and an external environmental detector, both electrically connected to the controller, to detect the environment within the sealed space and the external environment of the airbag assembly 1, and transmit the detection results to the controller. The environmental adjustment assembly 2 is disposed within the sealed space and electrically connected to the controller to adjust the environmental conditions within the sealed space in real time. The stealth cloak 3 is placed over the vehicle body of the radar equipment to absorb radar waves emitted from the radar equipment's array onto the vehicle body.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the airbag assembly 1 forms a sealed space on the ground. The radar equipment is parked inside the sealed space. The airbag assembly 1 provides a sealed, windproof, and rainproof space for parking, operation, and maintenance of the radar or radar command and control vehicle. The internal environment detection device is used to collect environmental conditions within the sealed space, such as humidity, temperature, and salt spray deposition, and transmits the collected data back to the controller in real time. The controller compares this real-time internal environment data with preset data set inside the space. For example, the preset data sets the temperature between 5℃ and 25℃, humidity ≤50%, and salt spray deposition <300μg / cm³. 2 When the real-time internal environmental data falls outside these preset data ranges, the controller transmits signals to the environmental conditioning component 2 to perform operations such as desalination, dehumidification, cooling, or heating. Preferably, the external environment detection component is used to collect data on the surrounding environment of the airbag component 1, such as wind force, rainfall, and snowfall, and transmits the collected external environmental data back to the controller in real time. The controller compares this real-time external environmental data with preset data set inside. For example, if the preset data sets the wind force to be less than level 7, the airbag component 1 needs to be inflated to 10000Pa. When the real-time external environmental data shows a wind force of level 7, the controller transmits signals to the environmental conditioning component 2 to inflate the airbag component 1. After the radar equipment is parked in a confined space, the stealth cloak 3 covers the outside of the vehicle body, exposing the radar array facets so that the array facets can normally emit radar waves. The stealth cloak 3 can absorb radar waves reflected from the system and emitted from the array facets to the stealth cloak 3, as well as radar waves emitted from the enemy into the stealth cloak 3 that are in the same band as the friendly radar's operating band.

[0031] Preferably, the stealth cloak 3 comprises a foam matrix and absorbent powder, wherein the foam matrix acts as a molecular cross-linked network structure, and the absorbent is preferably a ferrite absorber, which absorbs waves, making the stealth cloak 3 as light as 800g / ㎡, with a wide absorption bandwidth, capable of absorbing electromagnetic waves from 1GHz to 40GHz, and a flat plate reflectivity of <-10dB. Simultaneously, the stealth cloak 3 adopts a modular design, with each module weighing 20Kg. It is connected by connecting ropes, and the modules can be laid to cover the ground inside the protection system and the surface of vehicles, completely absorbing radar waves emitted from the radar array without any clutter interfering with radar operation.

[0032] In a preferred embodiment of the present invention, the internal environment detection device includes a humidity acquisition unit, a temperature acquisition unit, and a salt spray acquisition unit, which are electrically connected to the controller, respectively, to collect the humidity, temperature, and salt spray deposition of the air in the enclosed space and feed them back to the controller.

[0033] The system includes a humidity acquisition unit electrically connected to the controller, which can be a hygrometer that collects humidity data from the air in the enclosed space and feeds back real-time humidity data to the controller. A temperature acquisition unit is also electrically connected to the controller, which can be a thermometer that collects temperature data from the air in the enclosed space and feeds back real-time temperature data to the controller. A salt spray acquisition unit is also electrically connected to the controller, which can be a chloride ion content testing device that measures the chloride ion content in the air in the enclosed space. Since salt spray deposition is typically determined by chloride ion content, measuring chloride ion content determines the amount of salt spray deposition. The salt spray acquisition unit collects data and feeds back real-time salt spray deposition data to the controller, allowing the controller to compare the actual internal environmental data of the enclosed space with preset data and adjust the humidity, temperature, and salt spray deposition amount accordingly. Preferably, the temperature acquisition accuracy is 0.1℃, the humidity acquisition accuracy is 0.5%, and the salt spray deposition amount acquisition accuracy is 0.05μg / cm³. 2 .

[0034] In a preferred embodiment of the present invention, the external environment detection device includes a wind power acquisition unit and a precipitation acquisition unit that are electrically connected to the controller, respectively, to collect wind power, rainfall and snowfall outside the airbag assembly 1 and feed them back to the controller.

[0035] The wind data acquisition unit, which can be an anemometer or wind speed measuring instrument, collects wind data from the external environment where the airbag assembly 1 is located and promptly feeds the real-time wind data back to the controller. The controller compares the real-time wind data with preset data within the controller, thereby automatically adjusting the pressure of the airbag arch 12 and airbag door 11 to withstand winds of force 10 or higher. The precipitation data acquisition unit, which can be a rain sensor or rain gauge, automatically records data and processes the collected data before feeding it back to the controller. The controller compares the real-time precipitation data with preset data within the controller, thereby automatically adjusting the pressure of the airbag arch 12 and airbag door 11 to withstand larger amounts of rainfall.

[0036] In a preferred embodiment of the present invention, the environmental control component 2 includes a temperature regulator and a humidity regulator disposed in a sealed space. The temperature regulator is electrically connected to the controller to adjust the air temperature and salt spray deposition in the sealed air in real time, and the humidity regulator is electrically connected to the controller to adjust the air humidity and salt spray deposition in the sealed space in real time.

[0037] like Figure 1 and Figure 4 As shown, the temperature regulator can be an air conditioner, which also functions as a humidity regulator for dehumidification. When the temperature of the enclosed space is below 5℃ or above 25℃, the controller activates the air conditioner to adjust the temperature. When the humidity of the enclosed space is above 50%, the controller activates the humidity regulator or the dehumidification function of the air conditioner to dehumidify, ensuring that the humidity of the enclosed space is less than or equal to 50%. Furthermore, when the salt spray deposition is greater than or equal to 300 μg / cm³... 2 When the controller activates the temperature regulator for constant humidity cooling, or the humidity regulator for constant temperature dehumidification, or both the temperature regulator and humidity regulator can be activated simultaneously for dehumidification cooling, all of which can achieve the effect of reducing salt spray deposition.

[0038] In a preferred embodiment of the present invention, the airbag assembly 1 includes an airbag door 11, an airbag arch 12 and an inflation device. The inflation device is electrically connected to a controller. The airbag arch 12 is mounted on the outside of the radar equipment and communicates with the inflation device. The airbag door 11 is connected to one end of the airbag arch 12 and communicates with the inflation device to provide an access passage for the radar equipment.

[0039] like Figure 1 , Figure 2 and Figure 4As shown, the airbag arch 12 is an arched structure with openings at both ends, mounted on the outer periphery of the radar equipment. The left and right sides of the airbag arch 12 are fixed to the ground, and the front and rear sides are open and equipped with embedded airbag doors 11. The two airbag doors 11 are connected to the airbag arch 12 to form a sealed space, which isolates the external environment of the airbag assembly 1 from the sealed space. When the airbag doors 11 are opened, they can provide an access passage for the radar equipment. Preferably, the size of the airbag doors 11 is 6000mm*6000mm to ensure convenient access for personnel and radar equipment.

[0040] Preferably, the airbag assembly 1 further includes an airbag pressure acquisition unit disposed in the airbag arch 12 and the airbag door 11 respectively, which can acquire pressure data in the airbag arch 12 and the airbag door 11, and control the pressure of the airbag arch 12 and the airbag door 11 to be in a stable state through a controller. When the pressure is too low, the airbag arch 12 and the airbag door 11 are inflated by an inflation device, and the airbag is deflated when the pressure is too high.

[0041] Preferably, the high-strength windproof belt 4 is 5cm wide, made of aramid fiber, has good aging resistance, and can withstand a tensile force of more than 5 tons.

[0042] In a preferred embodiment of the present invention, the airbag arch 12 includes an airbag body 121, an annular sling, and a rope strap. A plurality of airbag bodies 121 are arranged side by side and fixed by a plurality of annular slings spaced apart. The rope straps spaced apart pass through the plurality of annular slings to fix the annular slings. The airbag body 121 is made of an airbag membrane, which includes a self-cleaning layer 1211, a surface weather-resistant coating 1212, a surface airtight coating 1213, a membrane substrate 1214, an inner airtight coating 1215, and an inner weather-resistant coating 1216 arranged from the outside to the inside.

[0043] like Figure 3As shown, the present invention comprises 13 airbag bodies 121, each with a diameter of 2m. The 13 airbag bodies 121 are arranged side by side to form an arched airbag frame 12, and are bound together by a ring-shaped sling. The ring-shaped sling is perpendicular to the airbag body 121, and is then bound and fixed by a rope strap passing through it. Preferably, the airbag body 121 is made of a high-strength airtight membrane material, and the entire airbag assembly 1 adopts a metal-free design. All O-rings and pulleys are made of high-strength plastic or high-strength polyester to avoid metal parts affecting the normal detection operation of the radar. Applying PVC material to the outer surface of the membrane substrate 1214 can form a surface airtight coating 1213, and applying PVC material to the inner surface of the membrane substrate 1214 can form an inner airtight coating 1215. Thus, the surface airtight coating 1213 and the inner airtight coating 1215 combine to protect the membrane substrate 1214 located between them, thereby increasing the waterproofness of the membrane substrate 1214. The surface weather-resistant coating 1212 is coated with PVDF on the outer surface of the surface airtight coating 1213, and the inner weather-resistant coating 1216 is coated with PVDF on the inner surface of the inner airtight coating 1215. PVCF mainly refers to vinylidene fluoride homopolymer or copolymer of vinylidene fluoride with other small amounts of fluorinated vinyl monomers. In its chemical structure, it is bonded by fluorine-carbon bonds, and its short-bond structure forms the most stable and strong bond with hydrogen ions. Therefore, the surface weather-resistant coating 1212 and the inner weather-resistant coating 1216 generated by coating with PVDF have unique physicochemical properties, which makes the film substrate 1214 not only have strong wear resistance and impact resistance, but also have high resistance to fading and ultraviolet radiation in extremely harsh and severe environments, and can withstand radiation intensity of up to 1120W / ㎡.

[0044] In a preferred embodiment of the present invention, the airbag assembly 1 further includes a stealth layer group 13 disposed on the outside of the airbag arch 12 and the airbag door 11 to ensure that the radar equipment is transparent to radar waves and shields external radar waves, infrared rays and visible light.

[0045] like Figures 1 to 3 As shown, the stealth layer 13 is used for visible light and infrared stealth, ensuring radar transmission in the working band and reflection in the out-of-band band. The stealth layer 13 and the stealth cloak 3 work together to ensure effective stealth protection under normal radar operation.

[0046] In a preferred embodiment of the present invention, the stealth layer group 13 includes a visible infrared coating 131, a stealth substrate 132, and a frequency selective layer 133. The visible infrared coating 131 is sequentially coated on one side surface of the stealth substrate 132, and the frequency selective layer 133 is connected to the other side surface of the stealth substrate 132 away from the visible infrared coating 131, so as to selectively transmit radar waves and reflect and shield radar out-of-band waves. The frequency selective layer 133 is attached to the outside of the airbag arch 12.

[0047] like Figure 1 , Figure 4 and Figure 5 As shown, the stealth layer 13 adopts a layered structure to achieve multiple functions such as visible light, infrared, and radar stealth. The total thickness is less than 0.8 mm. The stealth substrate 132 provides a coating base for the visible light and infrared coating 131 and the frequency-selective layer 133. The visible light and infrared coating 131 is coated on the outer surface of the stealth substrate 132, providing visible light and infrared stealth for radar equipment in a confined space. The presence of the frequency-selective layer 133 ensures that the radar equipment can transmit waves normally in its operating band and provides radar shielding stealth for the radar equipment, thereby ensuring the normal operation of the radar equipment. The visible light and infrared coating 131 adopts a camouflage pattern designed with refined target imitation camouflage, and the camouflage pattern is segmented and refined to imitate the target. The camouflage pattern is then integrated with the environmental colors of the airbag-type multi-functional radar equipment protection system, resulting in a visible light contrast of less than 0.1 between the infrared stealth coating and the standard color chart, and an infrared contrast of less than 0.2. This allows the stealth substrate 132 to achieve both visible light and infrared stealth effects. The frequency-selective layer 133 is connected to the side of the stealth substrate 132 away from the infrared stealth coating. When the stealth layer group 13 covers the surface of the airbag assembly 1, the frequency-selective layer 133 is close to the radar equipment. It can selectively transmit the radar equipment's operating waveband through the frequency-selective layer 133, while simultaneously reflecting and shielding the radar out-of-band waveband outside the stealth substrate 132, thereby meeting the radar's normal operating wave transmission requirements. The stealth substrate 132 is made of 500D polyester material with a warp and weft tensile strength of 1800N / 1600N / 5cm, which makes its warp tensile strength ≥1800N / 5cm and weft tensile strength ≥1600N / 5cm. This can maximize the tensile strength of the stealth substrate 132. In addition, the 500D polyester material is a flexible material, which makes the stealth cloak 3 soft and retractable, with good mobility.

[0048] In a preferred embodiment of the present invention, the frequency selection layer 133 includes frequency selection units 1331 and frequency selection protective layer 1332. A plurality of frequency selection units 1331 are arranged at equal intervals on the stealth substrate 132, and the frequency selection protective layer 1332 is disposed on the side surface of the frequency selection units 1331 away from the stealth substrate 132 to provide protection for the frequency selection units 1331.

[0049] like Figure 5As shown, the size and total perimeter of the frequency selective unit 1331 depend on the radar operating band. Each frequency selective unit 1331 has a transmittance of ≥80% to the radar operating band and a transmittance of ≤10% to out-of-band bands outside the radar operating band. It can selectively transmit the radar operating band and shield or reflect the out-of-band bands. A frequency selective protective layer 1332 is provided on the surface of the frequency selective unit 1331 away from the stealth substrate 132 to provide wear-resistant, salt spray-resistant and other protective layers for the frequency selective unit 1331.

[0050] Preferably, the frequency selection unit 1331 is made of metal paste and volatile organic compound and printed with a bandpass pattern. The metal paste and volatile organic compound are mixed in a liquid state. The mixture is heated to 100°C and begins to boil. When the temperature reaches 150°C, the volatile organic compound begins to evaporate and form a blank area. At the same time, the metal paste solidifies into a paste area. The blank area and the paste area together form the frequency selection unit 1331. Then, a bandpass pattern is printed on the frequency selection unit 1331, wherein the bandpass pattern is determined by the radar operating band. The frequency selective protective layer 1332 is made of resin, cement pigment, and binder. The resin in a molten state is mixed with the cement pigment and binder to form ink. The cement pigment provides the most basic material for color in the ink, while the resin is the carrier of the cement pigment in the ink. The binder determines the viscosity, tack, drying properties, and flowability of the ink. The ink is coated on the surface of the frequency selective body by ink printing to form a frequency selective protective layer 1332 with a thickness of 0.05 mm, which provides protection for the frequency selective unit 1331. The wear resistance level can reach B1 level, and it can withstand 96 hours of acidic salt spray test, thus enabling the stealth skin to be used in coastal areas.

[0051] In a preferred embodiment of the present invention, the airbag-type multi-functional radar equipment protection system further includes a high-strength windproof belt 4, a counterweight load 5, and a high-strength connecting belt 6. The high-strength connecting belt 6 is disposed on the outer periphery of the airbag assembly 1, and the airbag arch frame 12 is obliquely connected to the ground through the high-strength connecting belt 6. The counterweight load 5 is respectively disposed on the inner bottom and outer bottom of the airbag arch frame 12.

[0052] like Figure 1 and Figure 2 As shown, the high-strength connecting belt 6 forms a mesh structure covering the outer periphery of the airbag arch frame 12. The left and right sides of the airbag arch frame 12 are fixed to the ground by being diagonally pulled by the high-strength connecting belt 6. The edge of the high-strength windproof belt 4 is pulled to the ground by the counterweight load 5, which tightly stretches the high-strength windproof belt 4 to the outer surface of the airbag arch frame 12, thereby ensuring that the airbag assembly 1 can be used normally under the action of level 10 wind. When this airbag-type multi-functional radar equipment protection system is subjected to wind load, the airbag arch frame 12 will evenly transfer the force to the high-strength windproof belt 4, and finally transfer the force to the counterweight load 5, avoiding stress concentration in the airbag assembly 1.

[0053] The airbag component 1 of the airbag-type multi-functional radar equipment protection system of the present invention provides a sealed, windproof, and rainproof parking, working, and maintenance space for radars or radar command and control vehicles parked inside; the environmental detection component is used to monitor external wind, rain, and snow environments and internal temperature, humidity, and salt spray environmental factors in real time; the controller and environmental regulation component 2 is used to control the airbag pressure in real time to ensure the strength of the airbag-type multi-functional radar equipment protection system, and at the same time to regulate the internal temperature, humidity, and salt spray content of the system in real time to ensure that the internal space is dry and salt-free, providing a good working and parking environment for radar equipment such as radar command and control vehicles used in the field or along the coast of my country; the high-strength windproof belt 4, the counterweight load 5, and the high The strong connection band 6 and other windproof anchors provide ground anchoring for the airbag-type multi-functional radar equipment protection system, ensuring its normal operation under winds of up to level 10. The stealth cloak 3 is used to absorb radar waves reflected from the internal radar operating band of the multi-functional protection system. When the enemy radar detection band and our radar operating band are the same, it can absorb the enemy detection radar waves, ensuring that the radar waves reflected from the internal radar of the multi-functional protection system do not affect the normal operation of the radar, and has good anti-detection function. The stealth layer group 13 provides visible light, infrared stealth and radar shielding stealth for the multi-functional protection system. At the same time, the presence of the frequency-selective coating ensures normal radar transmission in the radar operating band, ensuring the normal operation of the radar.
