The vertical partition is located inside the chassis body and is arranged parallel to the side wall of the chassis body. The receiving antenna cavity and the transmitting antenna cavity are respectively located on both sides of the vertical partition. The horizontal partition is connected to the top of the vertical partition, and the main unit receiving cavity is formed between the horizontal partition and the chassis cover.

[0021] As described in the background section, 3D ground-penetrating radar systems achieve large-area rapid scanning through antenna arrays. Current 3D ground-penetrating radar systems suffer from the following problems: 1. Rigid Structure: The array housing housing the antenna units has fixed slots, and the position of each antenna unit is strictly limited. This means that once the number and spacing of antenna channels are determined, they cannot be changed, lacking flexibility and unable to be adjusted according to different detection needs. 2. Low Integration: Antennas, main unit, and cables are all independent components, making on-site assembly complex. Exposed cables are easily damaged in harsh field environments, affecting system stability and reliability. 3. Inconvenient Maintenance: The rigid structure makes repair or replacement extremely difficult when an internal antenna or main unit module malfunctions, requiring extensive disassembly.

[0022] Based on this, this application proposes a three-dimensional ground-penetrating radar system to solve the problems of rigid structure, low integration and inconvenient maintenance of existing three-dimensional ground-penetrating radar systems.

[0023] In some embodiments, a three-dimensional ground-penetrating radar system, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes: At least two antenna elements, each of which includes multiple antenna modules 10; The host module 20 is electrically connected to the antenna module 10 of the at least two antenna units; The array chassis 30 includes an antenna housing cavity 31 and a host housing cavity 32. The at least two antenna elements are located in the antenna housing cavity 31, and the host module 20 is located in the host housing cavity 32. The host module 20 and the array chassis 30 are detachably connected. Elastic spacers 40 are used to limit the spacing between two adjacent antenna modules 10 and between the antenna module 10 and the array chassis 30.

[0024] Specifically, the antenna unit is used to classify the antenna modules 10, and each antenna unit includes multiple antenna modules 10 of the same type. The host module 20 is used to receive data transmitted by each antenna module 10 in the antenna unit and analyze the data to obtain the detection results of the three-dimensional ground penetrating radar system. The host module 20 is the "brain" of the three-dimensional ground penetrating radar system.

[0025] In addition, both the host module 20 and the antenna unit are located inside the array chassis 30, and the wires connecting the host module 20 and the antenna unit are also located inside the search array chassis 30, which realizes the integrated setup of the host module 20, the antenna unit and the wires, and improves the integration of the three-dimensional ground penetrating radar system.

[0026] Multiple antenna modules 10 are arranged in an array within the antenna housing cavity 31. The antenna modules 10 are stably positioned relative to the antenna housing cavity 31 under the elastic clamping action of the elastic spacer 40, thereby achieving a limiting and spacing function within the array housing 30.

[0027] It should be noted that the antenna module 10 is located within the antenna receiving cavity 31, and its periphery is provided with elastic spacers 40. Multiple elastic spacers 40 work together to clamp the antenna module 10, thereby fixing its position within the antenna receiving cavity 31. The array pattern of the multiple antenna modules 10 can be adjusted according to actual usage needs; simply replacing the elastic spacers 40 with different specifications is sufficient. The elastic spacers 40 are elastic objects with a certain limiting function, and can be sponges.

[0028] For example, if the antenna modules 10 are arranged in an array of 8 units with a spacing of 10 cm in the antenna housing cavity 31, then the 8 antenna modules 10 are arranged side by side in the antenna housing cavity 31 with a spacing of 10 cm. The width of the elastic spacer 40 located between two adjacent antenna modules 10 should be 10 cm. The width of the elastic spacer 40 located between the antenna module 10 and the side wall of the antenna housing cavity 31 should be adapted to the distance between the antenna module 10 and the side wall of the antenna housing cavity 31.

[0029] In this embodiment, by setting the host module 20 to be detachably connected to the array chassis 30, and using elastic spacers 40 to limit the spacing of the antenna modules 10 within the antenna housing cavity 31, the antenna modules 10 are detachably connected to the array chassis 30 and the array is adjustable. This allows for an adjustable number and spacing of antenna modules 10 in the 3D ground-penetrating radar system, achieving flexibility in the setup of the antenna modules 10 and improving the flexibility and practicality of the 3D ground-penetrating radar system. Furthermore, the host module 20 and the antenna units are located within the array chassis 30 via the host housing cavity 32 and the antenna housing cavity 31, respectively, improving the integration of the 3D ground-penetrating radar system and enhancing its stability and reliability. In addition, the detachable arrangement of both the antenna modules 10 and the host module 20 relative to the array chassis 30 allows for partial disassembly, repair, or replacement of the 3D ground-penetrating radar system in case of a malfunction in either the antenna module 10 or the host module 20, thus improving the maintenance convenience of the 3D ground-penetrating radar system.

[0030] In some embodiments, such as Figure 2 As shown, the antenna housing cavity 31 includes a receiving antenna housing cavity 31 and a transmitting antenna housing cavity 31. The at least two antenna elements include a transmitting antenna element and a receiving antenna element. The transmitting antenna element is located inside the transmitting antenna housing cavity 31, and the receiving antenna element is located inside the receiving antenna housing cavity 31. The two adjacent antenna modules 10 belonging to the same antenna unit are spaced apart by the elastic spacer 40.

[0031] Specifically, the transmitting antenna unit is used to transmit signals, and the receiving antenna unit is used to receive signals. Both the transmitting and receiving antenna units include multiple antenna modules 10, each of which performs its corresponding function. For example, the multiple antenna modules 10 belonging to the transmitting antenna unit are all used to transmit signals. Setting the antenna housing 31 as both the receiving and transmitting antenna housings facilitates the setup of the transmitting and receiving antenna units, thereby improving the practicality of the three-dimensional ground-penetrating radar system.

[0032] In addition, the antenna receiving cavity 31 includes the receiving antenna receiving cavity 31 and the transmitting antenna receiving cavity 31. Multiple antenna modules 10 located in the receiving antenna receiving cavity 31 are arranged adjacent to each other, and multiple antenna modules 10 located in the transmitting antenna receiving cavity 31 are arranged adjacent to each other. Two adjacent antenna modules 10 belonging to the same antenna unit are limited and spaced apart by the elastic spacer 40. Antenna modules 10 belonging to different antenna units are located in different receiving cavities and are arranged independently of each other.

[0033] In this embodiment, the at least two antenna units include a transmitting antenna unit and a receiving antenna unit. The antenna housing 31 includes a receiving antenna housing 31 and a transmitting antenna housing 31. The transmitting antenna unit is located within the transmitting antenna housing 31, and the receiving antenna unit is located within the receiving antenna housing 31. This allows for the classification and partitioning of the at least two antenna units, facilitating the setup of the transmitting and receiving antenna units and thereby improving the practicality of the three-dimensional ground-penetrating radar system.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the array chassis 30 includes a chassis body 33, a chassis cover 34, a horizontal partition 35, and a vertical partition 36 connected to each other. The vertical partition 36 is located inside the chassis body 33 and is arranged parallel to the side wall of the chassis body 33. The receiving antenna cavity 31 and the transmitting antenna cavity 31 are respectively located on both sides of the vertical partition 36. The horizontal partition 35 is connected to the top of the vertical partition 36, and the main unit receiving cavity 32 is formed between the horizontal partition 35 and the chassis cover 34. The main unit module 20 is located on the horizontal partition 35 and is detachably connected to the horizontal partition 35.

[0035] Specifically, the chassis body 33 and the chassis cover 34 are detachably and sealed to prevent external impurities from entering the array chassis 30, which is beneficial to improving the practicality of the three-dimensional ground penetrating radar system. The vertical partition 36 is located inside the chassis body 33 to decompose the antenna receiving cavity 31 inside the chassis body 33 into the receiving antenna receiving cavity 31 and the transmitting antenna receiving cavity 31. The horizontal partition 35 is connected to the top of the vertical partition 36 to form the host receiving cavity 32 between the top of the horizontal partition 35 and the chassis cover 34, so that the array chassis 30 can accommodate at least two antenna units and the host module 20, realizing the integration of the three-dimensional ground penetrating radar system, which is beneficial to improving the integration degree of the three-dimensional ground penetrating radar system and making it easier for users to use the three-dimensional ground penetrating radar system.

[0036] For example, the host module 20 and the horizontal partition 35 are detachably connected by 3M double-sided hook and loop fasteners. The bottom of the host module 20 is provided with the hook side of the 3M double-sided hook and loop fasteners, and the area on the top surface of the horizontal partition 35 opposite to the host module 20 is provided with the rough side of the 3M double-sided hook and loop fasteners. The hook side and the rough side of the 3M double-sided hook and loop fasteners are glued together, so that the host module 20 and the horizontal partition 35 are detachably connected.

[0037] In some embodiments, such as Figure 2As shown, the top of the vertical partition 36 is provided with a horizontal support plate 37, and the horizontal partition 35 is connected to the vertical partition 36 through the horizontal support plate 37.

[0038] Specifically, the horizontal partition 35 is arranged parallel to the horizontal support plate 37, and the bottom surface of the horizontal partition 35 is connected to the top surface of the horizontal support plate 37. The horizontal support plate 37 can increase the connection area between the horizontal partition 35 and the vertical partition 36, thereby increasing the connection strength between the horizontal partition 35 and the vertical partition 36, which is beneficial to improving the connection stability between the horizontal partition 35 and the vertical partition 36.

[0039] It should be noted that multiple horizontal support plates 37 are provided at equal intervals on the vertical partition 36 to meet the connection requirements between the vertical partition 36 and the horizontal partition 35. At the same time, this avoids the horizontal support plates 37 occupying too much space of the antenna module 10 in the antenna receiving cavity 31, which is beneficial to the diversity of the arrangement of the antenna module 10 in the antenna receiving cavity 31.

[0040] In some embodiments, such as Figure 1 As shown, the chassis cover 34 includes a cover body 341 and a protrusion 342 protruding from the top of the cover body 341. The protrusion 342 is located on the top of the horizontal partition 35, and the host housing cavity 32 is formed between the protrusion 342 and the horizontal partition 35.

[0041] Specifically, the cover plate body and the protrusion 342 are integrally formed. The protrusion 342 is used to form the host housing cavity 32 between itself and the horizontal partition 35, so that the array chassis 30 has both the host housing cavity 32 and the antenna housing cavity 31. The protrusion 342 increases the internal volume of the array chassis 30, which is beneficial to the integrated installation of the host module 20 and the at least two antenna units in the array chassis 30.

[0042] In some embodiments, such as Figure 1 As shown, the chassis cover 34 is provided with a cable tray 343. The cable tray 343 has multiple cable holes on the bottom wall near the chassis body 33. The cable tray 343 is used to accommodate the wires connecting the host module 20 and the at least two antenna units. The wires pass through the cable holes and are connected to the host module 20 and the at least two antenna units.

[0043] Specifically, the cable tray 343 is used to accommodate coiled wires. The cable tray 343 is located on the chassis cover 34, near the bottom wall of the chassis body 33, i.e., the area where the chassis cover 34 and the cable tray 343 connect. It has multiple cable holes so that the coiled wires inside the cable tray 343 can extend out of the cable tray 343 and electrically connect to the antenna module 10 and the main module located inside the chassis body 33, thereby connecting the antenna module 10 and the main module. The cable tray 343 can prevent the wires connecting the antenna module 10 and the main module from being placed messily and disorderly inside or outside the array chassis 30, which is beneficial to improving the integration of the three-dimensional ground penetrating radar system and facilitating the maintenance of the three-dimensional ground penetrating radar system.

[0044] In some embodiments, the sidewall of the protrusion 342 is provided with a plurality of ventilation openings, and the ventilation openings are provided with dustproof and waterproof cooling fans.

[0045] Specifically, the main unit receiving cavity 32 is formed between the protrusion 342 and the horizontal partition 35. The ventilation port is provided on the side wall of the protrusion 342 and communicates with the main unit receiving cavity 32. The main unit module 20 is located inside the main unit receiving cavity 32. The main unit receiving cavity 32 is also connected to the antenna receiving cavity 31. Heat exchange with the external environment is achieved through the ventilation port, which can avoid the problem of the main unit module 20 and the at least two antenna units being affected by excessive temperature due to working heat, thus improving the service life of the three-dimensional ground penetrating radar system.

[0046] In addition, the dustproof and waterproof cooling fan installed on the vent can accelerate the heat exchange efficiency of the host housing 32 and the antenna housing 31, which is beneficial for thermal protection of the three-dimensional ground penetrating radar system. Furthermore, the dustproof and waterproof cooling fan can prevent external dust or water from entering the host housing 32 and the antenna housing 31 through the vent, thus preventing damage to the host module 20 and the at least two antenna units, which is beneficial for improving the service life and practicality of the three-dimensional ground penetrating radar system.

[0047] In some embodiments, such as Figure 1 As shown, the chassis cover 34 is provided with a structural connector 50, which is used to connect with an external structure. The three-dimensional ground-penetrating radar system is connected to the external structure through the structural connector 50.

[0048] Specifically, the structural connector 50, located on the chassis cover 34, prevents it from interfering with the operation of the at least two antenna units, allowing them to be located within the chassis and directly transmit signals to the ground, thus improving the practicality of the 3D ground-penetrating radar system. Furthermore, the structural connector 50 facilitates connection between the 3D ground-penetrating radar system and external structures, making it easier for users to operate the system and further enhancing its practicality.

[0049] For example, the structural connector 50 is connected to the front bumper of the vehicle, and the user moves the three-dimensional ground-penetrating radar system by driving the vehicle so that the three-dimensional ground-penetrating radar can complete its work, which can facilitate the user and reduce the user's workload.

[0050] In some embodiments, such as Figure 1 As shown, the structural connector 50 includes a first structural connector plate and a second structural connector plate. The first structural connector plate and the second structural connector plate are located on both sides of the center line of the chassis cover 34 and are symmetrically arranged with respect to the center line of the chassis cover 34.

[0051] Specifically, the arrangement of the first structural connecting plate and the second structural connecting plate can enhance the connection strength between the three-dimensional ground penetrating radar system and the external structure. Furthermore, the symmetrical arrangement of the first structural connecting plate and the second structural connecting plate with respect to the centerline of the chassis cover 34 ensures that the three-dimensional ground penetrating radar system is subjected to uniform force and remains horizontal, which is beneficial to the practicality of the three-dimensional ground penetrating radar system.

[0052] In some embodiments, such as Figure 1 As shown, the protrusion 342 is symmetrically arranged with respect to the center line of the chassis cover 34.

[0053] Specifically, the symmetrical arrangement of the protrusion 342 with respect to the centerline of the chassis cover 34 makes the main unit module 20 symmetrical with respect to the centerline of the chassis cover 34, thereby achieving a symmetrical arrangement of the three-dimensional ground penetrating radar system. On this basis, the symmetrical arrangement of the first structural connecting plate and the second structural connecting plate with respect to the centerline of the chassis cover 34 can further improve the uniformity of force and stability of the three-dimensional ground penetrating radar system during use, which is beneficial to the practicality of the three-dimensional ground penetrating radar system.
