Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, and in particular to an array antenna device for detecting unmanned aerial vehicles. Background Technology

[0002] The rapid development and widespread application of drone technology, while bringing convenience, has also triggered a series of problems such as privacy leaks and airspace security. Therefore, effective detection and control of drones is particularly important. Currently, most drone detection equipment on the market relies on capturing and analyzing specific radio signals such as drone remote control signals and image transmission signals. This type of technology becomes significantly less effective, or even ineffective, when facing drones flying in radio silence.

[0003] Existing detection equipment, limited by its antenna design and system architecture, generally suffers from limited detection coverage and blind spots. To achieve comprehensive monitoring of a specific area, multiple devices are often required, which not only increases system complexity and construction costs but also creates inconvenience for daily maintenance. Furthermore, some devices are bulky and consume a lot of power, making them unsuitable for flexible application scenarios such as temporary deployment and rapid response.

[0004] Therefore, there is an urgent need for a drone detection device that can achieve a wider range, higher precision, stronger environmental adaptability, and is easy to deploy. Utility Model Content

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0032] A specific embodiment of this utility model discloses an array antenna device for UAV detection, such as... Figure 1As shown, the device includes an array antenna module radome 1, a circumferential antenna array module 20, and a detection module 14. The radome 1 is located on the outermost side of the device, serving as a protective shield and providing environmental isolation. The circumferential antenna array module 20 is used to detect signals. The detection module 14 is used to process and analyze the electrical signals received and converted by the circumferential antenna array module 20 to identify the UAV target and its characteristic information.

[0033] Furthermore, the circumferential antenna array module 20 is connected to the detection module 14. Specifically, the circumferential antenna array module 20 is as follows: Figure 2 As shown, the circumferential antenna array module 20 includes detection elements 201. There are four or more detection elements 201 arranged at equal intervals in a fan-shaped angle on the outer side of the detection module 14, with the fan-shaped angle ranging from 36° to 90°. Preferably, there are ten detection elements 201, spaced at 36° central angles in a fan-shaped angle, with the detection direction facing outwards. The detection elements 201 can provide 360° omnidirectional detection within the spatial area.

[0034] Specifically, such as Figure 2 As shown, the detection element 201 includes an antenna radiating plate 2011, a first metal detection unit 2012, a second metal detection unit 2013, and a through hole 2014. The antenna radiating plate 2011 is configured as a triangular sheet structure, and its structural design is beneficial for signal transmission and radiation. The antenna radiating plate 2011 is mounted on the detection module 14.

[0035] Furthermore, the first metal detector 2012 is configured as a sheet-like rectangular structure, and is horizontally positioned in the middle of the antenna radiating plate 2011. The second metal detector 2013 is configured as two or more sheet-like rectangular structures with gradually varying lengths. Specifically, the second metal detectors 2013 are alternately distributed on the antenna radiating plate 2011, and are located on both sides of the first metal detector 2012. Preferably, there are 12 second metal detectors 2013, with 6 on each side of the first metal detector 2012. This alternating distribution of the first metal detector 2012 and the second metal detector 2013 enhances signal reception capability, improves signal detection sensitivity, and avoids signal interference between adjacent detector sheets.

[0036] Furthermore, both the first metal detection unit 2012 and the second metal detection unit 2013 are fixedly connected to the antenna radiating plate 2011 to ensure smooth signal transmission.

[0037] Furthermore, the through-hole 2014 is located at the center of the antenna radiating plate 2011 near the detection module 14. The through-hole 2014 penetrates the antenna radiating plate 2011. The through-hole 2014 makes the wiring inside the array antenna device more organized, which is conducive to heat dissipation inside the device and further improves the heat dissipation effect of the device.

[0038] Specifically, the circumferential antenna array module 20 employs multiple detection elements 201. The circumferential antenna array module 20 has a compact structure, occupies less space, and can further reduce the overall size of the device, lowering deployment difficulty, making it particularly suitable for scenarios with limited space. Multiple alternately distributed first metal detectors 2012 and second metal detectors 2013 can achieve more uniform signal coverage, improve the consistency and stability of signal detection, and effectively enhance the ability to identify UAV signals in complex electromagnetic environments. The circumferential antenna array module 20 has high signal reception efficiency, enabling it to capture UAV signals faster, shorten detection response time, and improve the detection capability for fast-moving UAVs.

[0039] Furthermore, the array antenna device also includes heat dissipation teeth 2, connecting posts 3, a first excitation source 4, a second excitation source 5, a third excitation source 6, a module mounting plate 7, a wind deflector 8, a mounting chassis 9, a bottom shell 10, a power module 11, a handle 12, a cooling fan 13, a power amplifier module 15, a waterproof fan 16, a switching module 17, a tripod mounting assembly 18, and a support post 19.

[0040] Specifically, the heat dissipation fins 2 are fixed to the cooling fan 13, and the heat dissipation fins 2 are used to increase the heat dissipation area and improve heat dissipation efficiency. The connecting post 3 is fixed to the circumferential antenna array module 20 and is used for fixed connection with the heat dissipation fins 2. The module mounting plate 7 is fixed to the mounting chassis 9, forming the main load-bearing structure of the array antenna equipment. The mounting chassis 9 is connected to the bottom shell 10, together forming the main shell of the array antenna equipment. The power module 11, the detection module 14, the power amplifier module 15, and the switching module 17 are connected to the module mounting plate 7. The power module 11 is used to supply power to the detection module 14, the power amplifier module 15, the cooling fan 13, and the waterproof fan 16. The detection module 14 is used to process the radio frequency signals received by the circumferential antenna array module 20 and to perform signal analysis and identification. The power amplifier module 15 is used to amplify the transmitted or received signals. The switching module 17 is used for data exchange between the internal modules of the array antenna equipment and external equipment. The handle 12 is fixed to the side of the bottom shell 10 for easy handling of the array antenna equipment. Waterproof fans 16 are respectively installed on the mounting base 9, and the waterproof fans 16 are used to form a forced air duct. The tripod mounting assembly 18 is installed at the bottom of the base shell 10, and the tripod mounting assembly 18 is used to connect the external support column 19 to achieve stable installation of the equipment.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
