Abstract
Description
Technical Field
[0001] This invention relates to the field of phased array radar testing technology, and in particular to a phased array radar antenna simulation device for testing. Background Technology
[0002] A phased array radar antenna is a radar array composed of a large number of identical radiating elements. Each radiating element is independently controlled in phase and amplitude by waveguides and phase shifters, resulting in a precise and predictable radiation pattern and beam pointing. It can simultaneously target multiple targets, offers high reliability and strong anti-jamming capabilities, and is adaptable to more complex environments, significantly improving the radar's survivability and anti-stealth capabilities. To study the structural load-bearing capacity of phased array radar antennas and the destructive effects of different types of loads, numerous destructive tests are required. However, conducting destructive tests on actual radar antenna targets is costly, time-consuming, and inefficient. To facilitate low-cost, rapid testing, a phased array radar antenna structure simulation device needs to be designed. This device can simulate the structural composition of a real radar antenna to a certain extent, reflecting its target physical characteristics to conduct relevant destructive tests and verify its structural load-bearing capacity.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

Furthermore, the terms "first" and "second" are merely used for descriptive distinction and have no special meaning.
[0034] like Figures 1 to 5As shown, this embodiment provides a test phased array radar antenna simulation device, which includes an antenna frame 1, four edge simulated antenna assemblies 2, two horizontal simulated antenna assemblies 3, two vertical simulated antenna assemblies 4, and a central simulated antenna assembly 5. The antenna frame 1 has nine mounting positions arranged in three rows and three columns. The central simulated antenna assembly 5, each edge simulated antenna assembly 2, each horizontal simulated antenna assembly 3, and each vertical simulated antenna assembly 4 are respectively mounted at one mounting position, and are structurally and physically equivalent to the central antenna assembly, edge antenna assembly, horizontal antenna assembly, and vertical antenna assembly in a real radar antenna. Specifically, the two vertical simulated antenna assemblies 4 and the central simulated antenna assembly 5 are arranged side-by-side along the length of the antenna frame 1, with the two vertical simulated antenna assemblies 4 located on either side of the central simulated antenna assembly 5. The four edge simulated antenna assemblies 2 are located at the four corners of the antenna frame 1. The overall structural distribution of the test phased array radar antenna simulation device is equivalent to that of a real radar antenna. By arranging four edge-simulated antenna assemblies 2, two horizontal-simulated antenna assemblies 3, two vertical-simulated antenna assemblies 4, and one central-simulated antenna assembly 5 in three rows and three columns on the antenna frame 1, the overall structure of the simulated phased array radar antenna is imitated. This makes the experimental phased array radar antenna simulation device highly similar to the structure of a real radar antenna, thereby improving the accuracy of the test. Specifically, when it is necessary to test the structural load-bearing capacity of a real radar antenna, this experimental phased array radar antenna simulation device, with a structure similar to that of a real radar antenna, is constructed to conduct destructive tests on it, verifying the destructive effects of different types of loads. This replaces the real radar antenna for structural strength testing, equivalently verifying the structural load-bearing capacity of the real radar antenna, which helps to reduce test costs, shorten the test cycle, and improve cost-effectiveness.
[0035] Specifically, such as Figure 1As shown, the antenna frame 1 includes a beam group 12, to which four edge analog antenna assemblies 2, two horizontal analog antenna assemblies 3, two vertical analog antenna assemblies 4, and a center analog antenna assembly 5 are connected. The beam group 12 includes four rectangular side beams 121 connected end to end and two first beams 122 arranged parallel to each other along the width of the antenna frame 1. Each first beam 122 and a side beam 121 is connected by two second beams 123 arranged parallel to each other along the length of the antenna frame 1. In this structure, the center analog antenna is located in the middle of the antenna frame 1 and is supported and connected to the two first beams 122. Each vertical analog antenna is supported and connected to one side beam 121 and two first beams 122. Each horizontal analog antenna is supported and connected to one side beam 121 and two corresponding second beams 123. Each edge analog antenna is supported and connected to a rectangular frame beam composed of two adjacent side beams 121, one first beam 122, and one second beam 123.
[0036] For example, the crossbeam assembly 12 is made of cold-formed hollow steel, for example, 200mm long, 50mm wide, and 10mm thick, with a cross-sectional dimension of 80mm × 80mm and a thickness of 5mm. Of course, in other embodiments, the dimensions of the crossbeam assembly 12 can also be other, specifically determined according to the dimensions of the actual radar antenna to be tested. The antenna frame 1 has a simple structure and low cost. Compared with the frame structure of the actual radar antenna, the structure of the antenna frame 1 is simpler, but the load-bearing effect is similar, which helps to save costs and assembly time, while ensuring the equivalence of the phased array radar antenna simulation device used in the test with the actual radar antenna, thereby improving the reliability of the test results.
[0037] Furthermore, such as Figures 2 to 4 As shown, the horizontal analog antenna assembly 3, the vertical analog antenna assembly 4, and the central analog antenna assembly 5 have the same structure, each including a first analog radome and a first analog substrate connected at intervals, and several analog antenna elements 103 connected to the first analog substrate. The first analog substrate is connected to the antenna frame 1. The edge analog antenna assembly 2 includes a second analog radome and a second analog substrate connected at intervals, with the second analog substrate connected to the antenna frame 1. The physical structure of each analog antenna assembly closely approximates that of a real antenna assembly, further improving structural equivalence.
[0038] The analog antenna array 103 can directly use an existing real antenna array, or it can adopt an equivalent structure. For example, the analog antenna array 103 includes a metal frame 1031, a microcrystalline glass dielectric rod 1032, and a ferrite magnetic rod. The ferrite magnetic rod is placed inside the metal frame 1031 and is glued to the metal frame 1031. The microcrystalline glass dielectric rod 1032 is coaxially placed at one end of the metal frame 1031 and is glued to the metal frame 1031. For example, the metal frame 1031 is an aluminum alloy shell, the ferrite magnetic rod is a cylinder with a size of φ10×100, and the microcrystalline glass dielectric rod 1032 is a cylinder with a size of φ16mm×25mm. Of course, in other embodiments, the material of the metal frame 1031 and the sizes of the ferrite magnetic rod and the microcrystalline glass dielectric rod 1032 can also be other, depending on the actual needs.
[0039] In this embodiment, the second analog substrate and the first analog substrate have the same structure. The first analog substrate and the second analog substrate each include a first analog antenna layer 1011 and a second analog antenna layer 1012 that are spaced apart and connected to both sides of the crossbeam assembly 12. They also each include a third analog antenna layer 1013 that is stacked with the second analog antenna layer 1012. The third analog antenna layer 1013 is located on the side of the second analog antenna layer 1012 that is away from the first analog antenna layer 1011. The analog antenna element 103 is connected between the first analog antenna layer 1011 and the second analog antenna layer 1012 of the first analog substrate, and one end of the analog antenna element 103 passes through the third analog antenna layer 1013 of the first analog substrate. Specifically, the microcrystalline glass dielectric rod 1032 is connected to the second analog antenna layer 1012 of the first analog substrate and passes through the third analog antenna layer 1013 of the first analog substrate. The end of the analog antenna element 103 that is away from the microcrystalline glass dielectric rod 103 is connected to the first analog antenna layer 1011 of the first analog substrate. Support plates 11 are spaced apart on the side beam 121, the first beam 122, and the second beam 123. For example, the support plates 11 are steel plates, 200mm long, 50mm wide, and 10mm thick, which helps to strengthen the structure and ensure the spacing between the first layer plate 1011 and the second layer plate 1012 of the simulated antenna. The first layer plate 1011 and the second layer plate 1012 of the simulated antenna are preferably fixedly connected to the crossbeam assembly 12 by screws. The structures of the first and second simulated substrates are simpler than those of a real simulated substrate, saving assembly time and reducing manufacturing costs. At the same time, they ensure that the stress conditions during testing are close to those of a real radar antenna, thereby guaranteeing the reliability of the test results.
[0040] Specifically, in the first analog substrate, a plurality of first connection holes are spaced apart on the first layer plate 1011 of the analog antenna, and a plurality of second connection holes are respectively opened on the second layer plate 1012 and the third layer plate 1013 of the analog antenna. One end of each analog antenna element 103 passes through a first connection hole. Specifically, one end of the analog antenna element 103, the microcrystalline glass dielectric rod 1032, passes through a first connection hole and is glued to the hole wall of the first connection hole. The other end of each analog antenna element 103 passes through a second connection hole. Specifically, the other end of the analog antenna element 103, the microcrystalline glass dielectric rod 1032, passes through a second connection hole and is glued to the hole wall of the second connection hole.
[0041] More specifically, such as Figure 3 and Figure 5 As shown, in the first and second analog substrates, a plurality of connecting posts 104 are spaced apart between the first analog antenna layer 1011 and the second analog antenna layer 1012, thereby enhancing the connection stability between the first analog antenna layer 1011 and the second analog antenna layer 1012. Exemplarily, both ends of the connecting posts 104 are connected to the first analog antenna layer 1011, the second analog antenna layer 1012, and the third analog antenna layer 1013 respectively by connecting screws 105. The connecting screws 105 pass through the first analog antenna layer 1011 and are threaded to one end of the connecting post 104; the connecting screws 105 pass through the third analog antenna layer 1013 and the second analog antenna layer 1012 and are threaded to the other end of the connecting post 104. The stable connection of the first analog antenna layer 1011, the second analog antenna layer 1012, and the third analog antenna layer 1013 is achieved through the connecting posts 104 and the connecting screws 105, resulting in a simple structure, easy assembly, and low cost.
[0042] In this embodiment, the first layer 1011, the second layer 1012, and the third layer 1013 of the analog antenna are all aluminum plates, resulting in lower manufacturing costs and structural strength close to that of a real antenna substrate. Exemplarily, the first layer 1011 has a thickness of 8 mm, the second layer 1012 has a thickness of 12 mm, and the third layer 1013 has a thickness of 8 mm. Of course, in other embodiments, the thicknesses of the first layer 1011, the second layer 1012, and the third layer 1013 can be other thicknesses, specifically determined based on the actual antenna substrate.
[0043] Furthermore, such as Figure 3 and Figure 5As shown, the first and second simulated antenna radomes have identical structures. Each radome includes a fourth simulated antenna plate 1021, a fifth simulated antenna plate 1022, and a sixth simulated antenna plate 1023 stacked sequentially. The fourth simulated antenna plate 1021 is spaced apart from the third simulated antenna plate 1013. The structures of the first and second simulated antenna radomes are similar to those of a real simulated substrate, ensuring that the stress conditions during testing closely resemble those of a real radar antenna, thereby guaranteeing the reliability of the test results.
[0044] Specifically, a plurality of connecting posts 104 are spaced apart between the fourth layer plate 1021 and the third layer plate 1013 of the analog antenna. That is, the first analog antenna radome and the first analog substrate, as well as the second analog antenna radome and the second analog substrate, are also spaced apart by connecting posts 104. Exemplarily, both ends of the connecting posts 104 are connected to the second layer plate 1012, the third layer plate 1013, the fourth layer plate 1021, the fifth layer plate 1022, and the sixth layer plate 1023 of the analog antenna, respectively, by connecting screws 105. Specifically, the connecting screw 105 passes through the second layer plate 1012 and the third layer plate 1013 and is threaded to one end of the connecting post 104; the connecting screw 105 passes through the sixth layer plate 1023, the fifth layer plate 1022, and the fourth layer plate 1021 and is threaded to the other end of the connecting post 104. This structure is simple, easy to assemble, and has low cost.
[0045] In this embodiment, the fourth layer plate 1021 and the sixth layer plate 1023 of the analog antenna are both epoxy glass cloth boards, and the fifth layer plate 1022 of the analog antenna is a rigid polyurethane foam board. This results in lower manufacturing costs and structural strength close to that of a real radome. Exemplarily, the thickness of the fourth layer plate 1021 is 1.5 mm, the thickness of the fifth layer plate 1022 is 35 mm, and the thickness of the sixth layer plate 1023 is 1.5 mm. Of course, in other embodiments, the thicknesses of the fourth layer plate 1021, the fifth layer plate 1022, and the sixth layer plate 1023 can be different, depending on the specific radome.
[0046] After the phased array radar antenna simulation device was assembled, it was vertically fixed to the ground using scaffolding, diagonal bracing, and other methods. The surface of the sixth layer plate 1023 of the simulated antenna served as the contact surface for different types of loads, and destructive tests were conducted to verify the destructive effects of different types of loads, thereby achieving equivalent testing of a real radar antenna. The phased array radar antenna simulation device used in this experiment is low in cost, simple to assemble, and can effectively shorten the test cycle and improve the cost-effectiveness ratio.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
