[0019] like Figures 1 to 4As shown, the coaxial device of the integrated anti-drone system includes a lifting mast 100, a radar detection unit 200, a radio detection unit 300, an electro-optical tracking unit 400, an jamming antenna unit 500, a turntable 600, and a control system. The lifting mast 100 has a preset length, is telescopic, and is vertically mounted on the top of an external vehicle. The radar detection unit 200 has a rectangular structure and is located on top of the lifting mast 100. The radio detection unit 300 has a ring structure and is mounted on the lifting mast 100, located at the top of the radar detection unit 500. The radio detection unit 300 and the radar detection unit 200 are located below the radar detection unit 200 and are coaxially arranged; the turntable 600 has a preset length and is located on the top of the external vehicle, and the turntable 600 and the lifting rod 100 are on the same plane; the jamming antenna unit 500 has a rectangular structure and is located on top of the turntable 600; the photoelectric tracking unit 400 has a block structure and is located on top of the jamming antenna unit 500; the control system is located on the external vehicle and the lifting rod 100 and the turntable 600 are electrically connected to the control system.

[0020] More specifically, such as Figure 1 and Figure 4As shown, the coaxial device of the integrated anti-drone system includes a lifting mast 100, a radar detection unit 200, a radio detection unit 300, an electro-optical tracking unit 400, a jamming antenna unit 500, a turntable 600, and a control system. The radar detection unit 200 first obtains information such as the target's distance, azimuth, altitude, and speed by emitting electromagnetic waves and receiving the echo signals reflected from the target. It has advantages such as long detection range, high accuracy, and all-weather operation, unaffected by factors such as light or weather. It can continuously detect, track, and identify drones during the day, night, or in adverse weather conditions, providing the anti-drone system with precise target location and motion status information to enable the system to make appropriate decisions. The radio detection unit 300 is mainly used to detect the drone's image transmission and remote control radio signals. Through analysis and processing of these signals, the drone's azimuth is determined using direction-finding and positioning algorithms, and even its specific location can be pinpointed. Furthermore, it can identify the drone's communication frequency band and signal characteristics, helping to determine the drone's type and operating status, providing a basis for subsequent countermeasures. The photoelectric tracking unit 400 utilizes infrared and visible light detectors to track UAV targets accurately and in real time. The infrared detector detects infrared radiation emitted by the UAV and operates even at night or in inclement weather, while the visible light detector provides high-resolution images in good lighting conditions to aid in identifying and defining the target. This unit extracts target feature information through an image processing unit, controlling the tracking turntable to always be aligned with the target, providing precise target pointing information for subsequent attacks or jamming, ensuring the integrated anti-UAV system's coaxial device can accurately target the objective. The jamming antenna unit 500 primarily emits jamming signals to disrupt the communication link between the UAV and its operator, or interfere with the UAV's navigation system. By emitting noise or false signals at specific frequencies, the UAV loses control and cannot receive correct commands, thus forcing it to return, land, or hover, effectively countering illegally intruding or illegally flying UAVs.

[0021] Among them, such as Figure 1As shown, to prevent interference between the radar detection unit 200 and the radio detection unit 300 during operation, a lifting mast 100 is installed. The radar detection unit 200 is positioned at the top of the lifting mast 100, which allows for vertical movement of the radar detection unit 200, enabling comprehensive detection. Simultaneously, the radio detection unit 300 is also positioned on the lifting mast 100, below the radar detection unit 200. The lifting mast 100 can simultaneously move both the radar detection unit 200 and the radio detection unit 300, maintaining a preset distance between them to avoid interference. Furthermore, the lifting mast 100 can move both the radar detection unit 200 and the radio detection unit 300 upwards and downwards, as well as the vehicle itself, ensuring omnidirectional detection by both units. It should be noted that the radio detection unit 300 receives signals, while the radar detection unit 200 transmits signals. The radar detection unit 200 can transmit signals as long as there are no obstructions throughout its 360-degree range. The coaxial design primarily ensures that the radar detection unit 200 transmits signals without obstruction in all 360 degrees. The radar detection unit 200 uses a pulse delay method for ranging. The distance to the target can be measured by the time it takes for the narrow electromagnetic pulse emitted by the radar detection unit 200 to travel back and forth once between the radar detection unit 200 and the target. To ensure range resolution, the beamwidth of the electromagnetic pulse signal emitted by the radar detection unit 200 is very narrow. Therefore, ensuring unobstructed movement within the 360° direction of the radar detection unit 200 is sufficient to guarantee omnidirectional detection.

[0022] More specifically, such as Figure 3 As shown, the turntable 600 is configured to coaxially mount the photoelectric tracking unit 400 and the jamming antenna unit 500. The turntable 600 can rotate the photoelectric tracking unit 400 and the jamming antenna unit 500 360 degrees, allowing for more comprehensive target tracking. Simultaneously, to prevent interference from the radar detection unit 200 and the radio detection unit 300 with the photoelectric tracking unit 400 and the jamming antenna unit 500, a preset distance is maintained between the lifting rod 100 and the turntable 600.

[0023] In one possible implementation, the radio detection unit 300 includes a detection group 310, a fixing ring 320, and a connecting rod 330; the detection group 310 has an umbrella-shaped structure, and the number of detection groups 310 is two or more; the fixing ring 320 is a hollow cylindrical structure with open ends, and the fixing ring 320 passes through the lifting rod 100; the connecting rod 330 has a preset length, and one end of the connecting rod 330 is connected to the outer peripheral wall of the fixing ring 320, and the other end of the connecting rod 330 is connected to the detection group 310.

[0024] More specifically, such as Figure 1 As shown, the specific structure of the radio detection unit 300 includes a detection group 310, a fixing ring 320, and a connecting rod 330. The detection group 310 has an umbrella-shaped structure, and the arrangement of two or more detection groups 310 allows for more comprehensive detection. The connecting rod 330 and the fixing ring are used to fix the detection group 310 to the lifting rod 100. Since the lifting rod 100 is a cylinder, the fixing ring 320 is a cylindrical structure with open ends. The other end of the connecting rod 330 has a preset angle with the lifting rod 100, and the detection group 310 has a preset angle with the horizontal plane. This arrangement allows the detection surface of the detection group 310 to face slightly upwards, thus improving detection accuracy. It should be noted that the radio detection unit 300 is a passive receiving device and does not emit electromagnetic waves itself. It relies on the surrounding detection group 310 to receive image transmission signals emitted by UAV targets from various directions. The detection group 310 also receives electromagnetic wave signals in space; therefore, the radar above it will not affect the reception of radio signals.

[0025] In one possible implementation, the interference antenna unit 500 includes an extension plate 510, a fixed plate 520, a spine antenna 530, a peripheral antenna 540, and a power amplifier 550. The fixed plate 520 is an inverted convex structure and is mounted on a turntable 600. The extension plate 510 has a preset length and is vertically mounted on the back of the fixed plate 520. There are two extension plates 510, and a preset distance exists between them. The turntable 600 is positioned between the two extension plates 510. The spine antenna 530 is a rectangular structure with a preset length and is mounted on the top of the fixed plate 520. There are two spine antennas 530. The peripheral antenna 540 is a rod-shaped structure and is mounted on the front of the fixed plate 520. There are two power amplifiers 550 mounted on the lower front of the fixed plate.

[0026] Among them, such as Figure 2As shown, the specific structure of the jamming antenna unit 500 includes an extension plate 510, a fixing plate 520, a spine antenna 530, a peripheral antenna 540, and a power amplifier 550. The extension plate 510 is provided to fix the fixing plate 520 onto the turntable 600; therefore, two extension plates 510 are provided, positioned behind the fixing plate 520, forming an "L" shape between them. The spine antenna 530, by adding a ridge structure at the waveguide outlet of the horn antenna, can widen the antenna's operating bandwidth, maintaining stable performance over a wider frequency range, making it suitable for multi-band jamming systems. Simultaneously, the ridge structure can optimize the internal electromagnetic field distribution of the antenna, reduce reflections, improve energy conversion efficiency, lower the VSWR, enhance the antenna's front-to-back ratio and cross-polarization isolation, reduce signal interference, and thus radiate the jamming signal more efficiently, interfering with the UAV's communication link or navigation system with stronger signal strength. The peripheral antenna 540 generally has omnidirectional or wide-angle radiation characteristics, enabling omnidirectional or large-angle signal coverage. Its gain is high; for example, some circumpolar antennas can achieve gains of over 6 dBi in specific frequency bands. It can detect and interfere with drone signals within a 360-degree range, effectively covering a certain area and ensuring that drones in different directions within that area are affected by the interference signal. This can block communication between the drone and its operator, or interfere with its navigation signals, causing the drone to lose control. Furthermore, the circumpolar antenna 540 also has good anti-multipath interference capabilities, allowing it to operate stably in complex electromagnetic environments and ensuring effective interference.

[0027] More specifically, there is a preset distance between the two spinal antennas 530, and the photoelectric tracking unit 400 is positioned between the two spinal antennas 530. The periodic antennas are of models 0.7-6 and 0.3-0.7. The advantages of the 0.7-6 model periodic antenna are: wide bandwidth, high gain, low cross-polarization, and convenient polarization adjustment. The advantages of the 0.3-0.7 model periodic antenna are: good low-frequency adaptability, low VSWR, and strong anti-interference capability.

[0028] The specific locations of the circumferential antennas are as follows: the 0.7-6 model circumferential antenna is positioned on the upper part of the mounting plate, and there is a preset angle between the 0.7-6 model circumferential antenna and the bottom of the mounting plate. The 0.3-0.7 model circumferential antenna is vertically positioned on the lower part of the mounting plate, and there are multiple 0.3-0.7 model circumferential antennas.

[0029] In one possible implementation, the lifting boom 100 includes a fixed cylinder and a telescopic shaft. The fixed cylinder is vertically mounted on the body of the external vehicle, and the telescopic shaft is housed inside the fixed cylinder. Both the radar detection unit and the radio detection unit are located on top of the telescopic shaft. The turntable 600 includes a fixed shaft and a rotating gimbal. The fixed shaft is vertically mounted on the body of the external vehicle, and the rotating gimbal is located on top of the fixed shaft, positioned between two extension plates. Both the lifting boom 100 and the turntable 600 are prior art and will not be described in detail here.

[0030] This application, through the above-mentioned configuration, achieves a coaxial design of the radar detection unit, radio detection unit, jamming antenna unit, and photoelectric tracking unit, and controls the radar detection unit, radio detection unit, photoelectric tracking unit, and jamming antenna unit through a control system. This solves the problem that the radar detection equipment, being on the same plane as the radio detection equipment, may have its target detection affected by obstructions.

[0031] 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 equivalent substitutions or changes made by those skilled in the art within the scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
