Description

Technical Field

[0001] The present application relates to the technical field of submarine decoy target production, and in particular to a submarine metal decoy target with full-size multi-target characteristics and a production and deployment method thereof. Background Art

[0002] Military camouflage technology has a long history. Concealing the truth and displaying the false are two inseparable aspects of military camouflage. Displaying the false is conducive to ensuring the concealment of the target, dispersing and attracting the enemy's attention and firepower, and improving military and economic benefits.

[0003] Submarine decoys are one of the important means of military camouflage and deception, and are of great significance for protecting the safety of real submarines. With the continuous development of military reconnaissance technology, submarine decoys also need to be continuously updated and upgraded to adapt to the new battlefield environment. For example, the development of remote sensing technology has made the concealment of the berthing state of submarines (including surface navigation and berthing) an important tactical consideration, which involves the safety and concealment of submarines when they are moored in ports, bases or hidden waters. Therefore, by preparing and deploying decoys at the dock, the enemy's reconnaissance system can be effectively confused, making it difficult for the enemy to accurately judge the position and status of the real submarine through remote sensing means, thereby protecting the safety of the real submarine; on the other hand, by deploying submarine decoys, the enemy can be forced to disperse its forces and waste resources, thereby confusing the enemy's decision-making and creating a tactical advantage.

[0004] Traditional false targets are mainly designed for enemy optical reconnaissance, and only pursue the similarity of the target's appearance optical characteristics. Traditional false targets are mostly made of inflatable models, which have the advantages of realistic appearance, light weight, easy transportation, and fast installation and withdrawal. However, with the rapid development of new reconnaissance technology, especially the emergence and application of radar and satellite technology, microwave and infrared reconnaissance have gradually become the mainstream of modern detection technology. Traditional optical false targets are different from real targets in terms of material, internal structure, etc., and their radar reflection cross-sectional area and infrared emission characteristics are obviously different from those of real missile vehicles. Therefore, it is increasingly difficult to adapt to the needs of war by only pursuing the similarity of the appearance contour and the visible light band. In the field of submarine false targets, the current inflatable submarine false targets are also difficult to meet the concealment requirements of submarines in the berthing state. Therefore, it is necessary to propose a new technical solution to solve the problems existing in the prior art. Summary of the invention

[0027] Compared with the prior art, this application has at least the following beneficial effects:

[0028] 1. Based on further analysis and research on the existing technical problems, the present application recognizes that under the background of the rapid development of microwave and infrared reconnaissance and detection technology, traditional inflatable false targets can hardly achieve military camouflage effects, especially the current inflatable submarine false targets can hardly meet the concealment requirements of submarines in the berthed state. Therefore, the present application provides a full-size submarine metal false target with multiple target characteristics. The false target is composed of a chassis, a keel structure and a skin. The shape and size of the false target are based on the structural size of the exposed part of the real target in the berthed state. It is a simulation structure of the real target. In particular, the present application sets a fuel injection heating device inside the structure of the false target. The false target can be heated by the fuel injection heating device to simulate the actual temperature of the real target. Therefore, the submarine metal false target provided by the present application adopts a metal material, and simulates the structural form of the exposed part of the real target in the berthed state, and simulates the actual temperature of the real target by internal heating, so as to maintain consistency with the real target in terms of multiple target characteristics such as shape, size, structure, material, temperature (infrared target characteristics), and provide cover for the real target submarine in the berthed state.

[0029] 2. In order to adapt to microwave detection technology, this application also configures a shore-based omnidirectional angular anti-array device and a floating omnidirectional angular anti-array device for the submarine metal decoy target. The settings of these two omnidirectional angular anti-array devices are used to enhance the radar wave target characteristics of the decoy target and further improve the camouflage effect.

[0030] 3. The chassis of the submarine metal decoy target provided by the present application adopts a pontoon splicing structure, so it is highly assemblable and can be assembled accordingly according to the shape and size of the part of the real target exposed above the water surface. Therefore, the present application can adapt to real target submarines of various shapes and sizes.

[0031] 4. In the present application, a steel structure reinforcement is provided on the chassis of the submarine metal decoy to prevent the decoy from being swayed and deformed due to the impact of waves on the decoy. The steel structure reinforcement may be a steel hoop that fastens the various pontoon modules together.

[0032] 5. In order to facilitate the movement of the submarine metal decoy target, the present application is provided with six hidden towing devices around the chassis, which can move the submarine metal decoy target to the target position by means of power devices such as tugboats.

[0033] 6. The keel structure in this application is the structural frame of the submarine metal decoy, which supports the skin and forms a simulation structure of the real target with the skin coated with the same color as the real target, which is consistent with the shape and structural characteristics of the real target, thereby improving the camouflage effect.

[0034] 7. In order to avoid exposing the intention of action after frequent towing by tugboats to form a regular pattern, the present application also sets a power device, a drive device and a control device on the chassis of the submarine metal decoy target. Such a structural design can realize the autonomous movement and steering of the submarine metal decoy target, and approach the real target in terms of movement characteristics.

[0055] Embodiment 1

[0056] This embodiment provides a submarine metal false target with full-scale multi-target characteristics, such as Figure 1 , 3 The submarine metal decoy mainly includes a chassis 1, a keel structure 2 and a skin 3. The chassis 1 is a spliced ​​plate-shaped structural member. The shape and size of the chassis 1 are respectively the same as the shape and size of the waterline contour of the real target in the berthing state; the keel structure 2 is installed above the chassis 1, and the keel structure 2 is composed of a plurality of steel beams. The skin 3 is welded and fixed on the surface of the keel structure 2 away from the chassis 1. The keel structure 2 is used to support the skin 3, and together with the skin 3, it forms a simulation structure that is the same as the structure of the part of the real target exposed above the water in the berthing state. A coating with the same color as the real target is arranged on the surface of the skin 3; a fuel injection heating device (not shown) is arranged in the space enclosed by the skin 3 and the chassis 1.

[0057] In a specific application example, the fake target is docked at the port, and the simulation requirements of the infrared target characteristics are different under different meteorological conditions. Under direct sunlight on a sunny day, the temperature of the fake target itself is much higher than the ambient temperature. At this time, it is in a natural state, and its characteristics are similar to those of the actual installation (real target) under the same environment, so no simulation is required. However, under weather conditions such as cloudy days, rainy days and nights, the infrared target characteristics of the fake target will be quite different from those of the actual installation. Considering that the internal space of the submarine fake target is relatively empty and the sealing performance is far inferior to that of the actual installation, the inventor proposes that an electronically controlled fuel injection heating method can be used inside the fake target to increase the temperature of the fake target itself, so as to simulate the infrared characteristics of the actual installation and improve the infrared target characteristics.

[0058] In one embodiment of the present application, the fuel injection heating device arranged inside the false target includes a fuel tank, a fuel pump, a fuel injector, an igniter, a combustion chamber, a temperature sensor and a controller, wherein the fuel pump is used to pump the fuel in the fuel tank into the fuel injector, the fuel injector is used to inject the fuel into the combustion chamber, the igniter is used to ignite the fuel injected into the combustion chamber, the temperature sensor is used to monitor the temperature inside the submarine metal false target in real time, the controller stores the internal temperature reference value of the real target, and the controller can send a control signal to the fuel injector to control the start and stop of the fuel injector according to the internal temperature reference value and the temperature signal obtained from the temperature sensor. Compared with other heating methods such as electric heating wires, this fuel injection heating method heats up more quickly and can quickly simulate infrared target characteristics that are similar to those of the real target.

[0059] In the above embodiment, the shape, size and color of the false target are based on the structural size and color of the part of the real target exposed to the water surface in the moored state, which is a simulation structure of the real target. The present application improves the camouflage effect of the false target by accurately simulating the shape and color of the real target, thereby improving the concealment and survivability of the real target; in addition, the present application sets a fuel injection heating device inside the structure of the false target, through which the false target can be heated, which can adjust the surface temperature of the false target according to the external ambient temperature, so that it can still maintain infrared characteristics similar to those of the real target under different weather conditions, thereby enhancing adaptability; at the same time, the chassis 1 in the present application adopts a splicing structure, which is easy to disassemble and maintain, and can quickly replace damaged parts, and can adapt to the production of false targets of various structural sizes; therefore, the submarine metal false target provided in the present embodiment adopts a metal material, and simulates the structural form of the part of the real target exposed to the water surface in the moored state, and simulates the actual temperature of the real target by internal heating, so as to maintain consistency with the real target in terms of multiple target characteristics such as shape, size, structure, material, temperature (infrared target characteristics), and provide cover for the real target submarine in the moored state.

[0060] In one embodiment of the present application, the chassis 1 of the decoy target is spliced ​​by pontoon bridges, and the cross-sectional shape of the waterline contour of the real target submarine is spliced ​​by pontoon bridges, so as to simulate the shape, structure and size of the part of the real target exposed above the water. Specifically, the chassis 1 is composed of a plurality of pontoon bridge modules, and the plurality of pontoon bridge modules are arranged in a grid shape on the same horizontal plane, such as Figure 4 Any two adjacent floating bridge modules are fastened together by a connector. The floating bridge module can be made of light, high-strength materials, such as aluminum alloy, steel or high-density polyethylene (HDPE) and other materials with good buoyancy and corrosion resistance. The floating bridge module used in this application can be a ready-made modular product, or it can be specifically customized according to the shape and size of the decoy target.

[0061] In one embodiment of the present application, in order to prevent the swaying deformation caused by the impact of waves on the false target, a steel structure can be used to reinforce the surroundings and bottom surface of the chassis 1. Specifically, steel structure reinforcement members (not shown), such as steel hoops and other structural members with a fastening function, can be arranged around the surroundings and bottom surface of the chassis 1.

[0062] In one embodiment of the present application, in order to facilitate the tugboat to tow the false target, no less than six hidden towing devices (one each at the front and rear of the false target and two each at the left and right, not shown) can be arranged around the chassis 1. In a specific manufacturing example, the hidden towing device includes a connecting seat fixed on the steel structure reinforcement member around the chassis 1 and a towing rope arranged on the connecting seat.

[0063] In one embodiment of the present application, Figure 5 The keel structure 2 is composed of a plurality of curved cross beams 21, a plurality of connecting vertical beams 22 and a plurality of supporting beams 23 to form a frame structure. The plurality of curved cross beams 21 are arranged in parallel and spaced in sequence along the length direction of the chassis 1, and the plurality of connecting vertical beams 22 are arranged in parallel and spaced in sequence along the width direction of the chassis 1. Each connecting vertical beam 22 is welded and fixed to the plurality of curved cross beams 21. The supporting beams 23 are installed under the curved cross beams 21 and are fixedly connected to the chassis 1. The bottom outer edge of the keel structure 2 is adapted and connected to the outer edge of the chassis 1.

[0064] During the specific production, the keel is made of high-strength, corrosion-resistant high-quality steel. Since the real target submarine has various shapes and sizes, when making the corresponding fake target, the corresponding keel structure 2 needs to be made according to the shape and size of the real target. The size and curvature of each keel (i.e., the curved cross beam 21, the connecting vertical beam 22 and the supporting beam 23) that constitutes the keel structure 2 are different. During production, each group of keels needs to be designed separately according to the specific structural shape. The overall structural layout and stress conditions of the submarine need to be fully considered during the design. The cross-sectional shape and size of the keel need to be accurately calculated and optimized to meet the requirements of strength and stability.

[0065] In one embodiment of the present application, the skin 3 is made of a light, high-strength metal material, such as aluminum alloy, titanium alloy, magnesium alloy or stainless steel. To ensure the flatness of the appearance, the skin 3 is constructed using a welding process. After the skin 3 is constructed, a coating similar to the target color is applied to the entire surface, including detail beautification.

[0066] In one embodiment of the present application, in order to avoid the exposure of action intention after the false target is frequently towed by a tugboat to form a regular pattern, a large generator driving the motor can be installed on the chassis 1 to support the autonomous transfer operation of the false target. Specifically, a power device, a drive device and a control device can be installed on the chassis 1; the power device includes a generator and a battery pack; the drive device includes a motor and a travel steering control mechanism, the motor is electrically connected to the output end of the generator and the battery pack respectively, the travel steering control mechanism includes a control mechanism steering gear, a transmission assembly and a rudder blade, the control mechanism steering gear is connected to the motor signal, the transmission assembly includes a first gear installed on the output shaft of the motor, and the rudder blade is provided with a second gear meshing with the first gear. The control mechanism steering gear is connected to the control device signal and can control the motor to rotate according to the signal received from the control device, thereby driving the rudder blade to swing; the control device includes a processor and a sensor module connected to the processor signal, the sensor module includes a GPS, a gyroscope and a speed sensor, and the processor outputs a command signal to the control mechanism steering gear according to the sensor signal received from the sensor module.

[0067] In the above embodiment, the design of the generator and the battery pack ensures the stability and endurance of the power. The electric motor is connected to the generator and the battery pack as a driving source, and the power source can be flexibly switched as needed. The travel steering control mechanism can achieve precise steering control through the combination of the steering gear, the transmission assembly and the rudder blade. The steering gear, as a control mechanism, can respond quickly according to the instructions sent by the control device. The transmission assembly ensures that the rotation of the motor can be effectively transmitted to the rudder blade through gear meshing (the first gear and the second gear meshing), thereby realizing the swing of the rudder blade. The gear transmission can enhance the torque output and improve the flexibility of the rudder blade rotation. The combination of the above GPS, gyroscope and speed sensor can obtain the position information and motion state of the model ship in real time. The processor can dynamically adjust according to these data, thereby outputting the command signal for controlling the steering gear. This feedback control system helps to improve the control accuracy of the model ship. Through the setting of the above power device, drive device and control device, the false target can adjust the heading in real time after receiving the sensor information, and the steering gear drives the rudder blade to change direction according to the control command, and has good steering ability.

[0068] Therefore, the submarine metal decoy provided in this embodiment is based on the structural dimensions of the part of the real target that is exposed above the water surface in the moored state, and is a simulation structure of the real target. In particular, the present application arranges a fuel injection heating device inside the structure of the decoy target, and the decoy target can be heated by the fuel injection heating device to simulate the actual temperature of the real target. Therefore, the submarine metal decoy provided in this application is made of metal material, and simulates the structural form of the part of the real target that is exposed above the water surface in the moored state, and simulates the actual temperature of the real target by internal heating, so as to maintain consistency with the real target in terms of multiple target characteristics such as shape, size, structure, material, temperature (infrared target characteristics), and provide cover for the real target submarine in the moored state.

[0069] Embodiment 2

[0070] This embodiment provides a submarine metal decoy target. This embodiment includes all the contents recorded in the above-mentioned embodiment one. Compared with the embodiment one, the submarine metal decoy target provided by this embodiment realizes the simulation of radar target characteristics.

[0071] This embodiment configures a shore-based omnidirectional corner reflector device 4 and a floating omnidirectional corner reflector device 5 for the submarine metal decoy target. During the specific deployment process, omnidirectional radar scattering cross-section coverage can be achieved through reasonable corner reflector array design and layout, which can achieve a better radar detection interference effect.

[0072] In this embodiment, the shore-based omnidirectional angle anti-array device 4 is arranged at the edge of the dock where the submarine metal decoy is docked, and a shore-based omnidirectional angle anti-array device 4 is arranged near the head, middle and tail of the submarine metal decoy, such as Figure 6 .

[0073] In a preferred embodiment of the present application, Figure 7 , 8 The shore-based omnidirectional corner reflector array device 4 includes a base frame and a multi-layer corner reflector array group installed on the base frame. Each layer of the corner reflector array group includes a plurality of corner reflectors 6 arranged in a circle along the circumference of the base frame. From the bottom of the base frame to the top of the base frame, the number of corner reflectors 6 constituting each layer of the corner reflector array group decreases layer by layer; a corner reflector 6 is arranged on the top of the base frame, and the open end face of the corner reflector 6 is away from the ground and parallel to the ground.

[0074] In this embodiment, Fig. 9 Each submarine metal decoy is equipped with two floating omnidirectional angular anti-array devices 5, and the two floating omnidirectional angular anti-array devices 5 are arranged relatively along the central axis direction of the submarine metal decoy, one floating omnidirectional angular anti-array device 5 is close to the head of the submarine metal decoy, and the other floating omnidirectional angular anti-array device 5 is close to the tail of the submarine metal decoy.

[0075] In a preferred embodiment of the present application, a floating omnidirectional corner reflector device 5 includes a floating seat and a vertical mounting rod arranged on the upper surface of the floating seat, and a plurality of omnidirectional corner reflector groups are arranged on the vertical mounting rod from bottom to top, each omnidirectional corner reflector includes eight corner reflectors 6, and the eight corner reflectors 6 are closely arranged to form a regular octahedron structure.

[0076] The corner reflector 6 used in the present application is an existing product, which can reflect the incident light or signal back to the original direction. The corner reflector is usually composed of three mutually perpendicular planes to form a three-dimensional structure similar to an L shape. This design ensures that no matter what the angle of the incident light is, the reflected light can always return along the incident direction.

[0077] Therefore, the submarine metal decoy provided in this embodiment has full-size and multi-target characteristics, including shape, size, structure, material, temperature (infrared target characteristics) and radar target characteristics, which can greatly improve the concealment of the real target submarine in the berthed state. This application not only solves the full-size preparation problem of the hull above the surface of the submarine decoy target, but also realizes the enhancement of the radar wave target characteristic effect of the submarine decoy target, as well as the simulation of the infrared target characteristic effect, which greatly improves the camouflage effect of the submarine in the berthed state and effectively meets the concealment application requirements of the berthed state.

[0084] In the above step S2, the keel is made of high-strength, corrosion-resistant high-quality steel. Since the real target submarine has various shapes and sizes, when making the corresponding false target, the corresponding keel structure 2 needs to be made corresponding to the shape and size of the real target. The size and curvature of each keel (i.e., the curved cross beam 21, the connecting vertical beam 22 and the supporting beam 23) that constitutes the keel structure 2 are different. When making, each group of keels needs to be designed separately according to the specific structural shape. When designing, the overall structural layout and stress conditions of the submarine need to be fully considered. The cross-sectional shape and size of the keel need to be accurately calculated and optimized to meet the requirements of strength and stability.

[0085] In the above step S3, the skin 3 is made of lightweight, high-strength metal materials, such as aluminum alloy, titanium alloy, magnesium alloy or stainless steel. To ensure the smoothness of the appearance, the skin 3 is constructed by welding. After the skin 3 is constructed, a coating similar to the target color is applied to the whole, including detail beautification.

[0086] Considering the subsequent deployment and installation work, it is also necessary to configure a shore-based omnidirectional angle anti-array device 4 and a floating omnidirectional angle anti-array device 5 for the submarine metal false target, wherein: the shore-based omnidirectional angle anti-array device 4 includes a base frame and a multi-layer corner reflector array group installed on the base frame, each layer of the corner reflector array group includes a plurality of corner reflectors 6 arranged in a circle along the circumference of the base frame, and the number of corner reflectors 6 constituting each layer of the corner reflector array group decreases layer by layer along the direction from the bottom of the base frame to the top of the base frame; a corner reflector 6 is arranged on the top of the base frame, and the open end face of the corner reflector 6 is away from the ground and parallel to the ground. In the specific installation and application process, the staff can set the number of corner reflectors 6 and the specific installation angle of each layer of the corner reflector array group according to the needs, as long as the final debugging can achieve omnidirectional radar scattering cross-section coverage. The corner reflector 6 used in this application is an existing product. The above-mentioned floating omnidirectional corner anti-array device 5 includes a floating seat and a vertical mounting rod arranged on the upper surface of the floating seat. Two omnidirectional corner anti-array groups are arranged on the vertical mounting rod from bottom to top. Each omnidirectional corner anti-array includes eight corner reflectors 6. The eight corner reflectors 6 are closely arranged to form a regular octahedron structure, thereby realizing omnidirectional radar scattering cross-section coverage.

[0087] Embodiment 4

[0088] This embodiment provides a method for deploying a submarine metal false target with full-scale multi-target characteristics, including the following steps:

[0089] L1: Dock the submarine metal decoy at the target dock;

[0090] L2: three shore-based omnidirectional angle anti-array devices 4 are arranged at the edge of the target dock, and the three shore-based omnidirectional angle anti-array devices 4 are respectively close to the head, middle and tail of the submarine metal false target;

[0091] L3: A floating omnidirectional angular anti-array device 5 is arranged at the head of the submarine metal decoy target, and a floating omnidirectional angular anti-array device 5 is arranged at the tail of the submarine metal decoy target. The two floating omnidirectional angular anti-array devices 5 are respectively connected to the submarine metal decoy targets.

[0092] In the above step L1, a fuel injection heating device is arranged inside the metal false target of the submarine docked at the target dock.

[0093] In the above steps L2 and L3, omnidirectional angle anti-arrays are used to enhance the radar wave target characteristics of the false target. Three groups of shore-based omnidirectional angle anti-arrays are used for each submarine false target, which are set up close to the edge of the target docking pier, with one group set up at the head, middle (near the island), and tail of the target; two groups of floating omnidirectional angle anti-arrays are used for each target, with one group set up before and after the target along the central axis, such as Figure 6 .

[0094] In summary, the present application provides a full-size multi-target submarine metal decoy and a method for making and deploying the same. The decoy consists of a chassis, a keel structure and a skin. The shape and size of the decoy are based on the structural size of the exposed part of the real target in the berthed state. It is a simulation structure of the real target. In particular, the present application sets a fuel injection heating device inside the structure of the decoy, and the decoy can be heated by the fuel injection heating device to simulate the actual temperature of the real target. In addition, the present application also configures a shore-based omnidirectional angular anti-array device and a floating omnidirectional angular anti-array device for the submarine metal decoy. The two omnidirectional angular anti-array devices are set up to enhance the radar wave target characteristics of the false target and further improve the camouflage effect; therefore, the submarine metal false target provided in the present application is made of metal material, and simulates the structural form of the part of the real target exposed above the water in the berthed state, and simulates the actual temperature of the real target by internal heating, and enhances the radar wave target characteristics of the false target by deploying and configuring the omnidirectional angular anti-array, so as to maintain consistency with the real target in multiple target characteristics such as shape, size, structure, material, temperature (infrared target characteristics) and radar wave target characteristics, thereby providing cover for the real target submarine in the berthed state.
