The core principle of the anti-drone radar detection device is based on the propagation and reflection of electromagnetic waves. The radar system emits electromagnetic waves of a certain frequency. These waves will be reflected when they encounter targets (such as ground objects, aircraft, or other obstacles). The reflected waves are received by the radar antenna and converted into electrical signals. By processing and analyzing these electrical signals, information such as the distance, azimuth, altitude, and speed of the target can be obtained.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the anti-drone radar system of the present invention will be introduced in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Combined with Figure 1 As shown, the present invention provides an anti-drone radar system, including a frame 1, a heat dissipation component 2 and a number of working devices. The frame 1 is the outer frame body of the entire anti-drone radar system, and the heat dissipation component 2 and the working devices are installed in the frame 1. The working devices are used to realize functions such as transmitting, receiving, signal processing and display control, so as to realize the function of detecting drones. The working devices will generate heat during use, and the heat dissipation component 2 is used to dissipate the heat to the outside to achieve cooling.

[0034] The working devices include a waveguide slot antenna 3. The waveguide slot antenna 3 is based on the mode transmission and radiation of the waveguide. By opening slots on the wide side or narrow side of the waveguide, electromagnetic waves are radiated from the slots to realize the transmission and reception of electromagnetic waves. The frame 1 is surrounded by four side walls on all sides to form a square structure, and is provided with a through hole in the front-rear direction; Figure 1 Among them, the Y-axis direction is the front-rear direction. The waveguide slot antenna 3 is installed at the front end of the frame 1 to block the front end face of the frame 1. The heat dissipation component 2 is installed at the rear end of the frame 1 to block the rear end face of the frame 1. Other working devices are installed in the space between the waveguide slot antenna 3 and the heat dissipation component 2.

[0035] The working devices include a TR component 4, a signal processing module 5 and a power supply module 6 that are in thermally conductive contact with the heat dissipation component 2. The TR component 4, the signal processing module 5 and the power supply module 6 are the devices with the largest heat generation among the working devices. The devices with the largest heat generation are directly in contact with the heat dissipation component 2. The heat dissipation component 2 absorbs the heat dissipated by the working devices and conducts the heat to the outside, conducts the internal heat to the outside, realizes the function of heat dissipation, and cools down the entire anti-drone radar system.

[0036] It should be noted that the heat dissipation component 2 is in thermally conductive contact with the TR component 4, the signal processing module 5 and the power supply module 6 respectively. It can either directly contact the TR component 4, the signal processing module 5 and the power supply module 6 in thermally conductive contact, or set materials such as thermal conductive silicone grease at the contact surface to meet the effect of heat conduction, reduce the thermal resistance, and improve the thermal conduction efficiency.

[0037] The drone radar system provided by the present invention enables the heat generated by the working components to be conducted outward in a timely and rapid manner through the reasonable arrangement of internal components, meeting the heat dissipation requirements of the anti-drone radar system. Heat is directly conducted from the working components to the heat dissipation component 2 through heat conduction, so there is no need to set up additional heat conduction structures, saving space inside the anti-drone radar system, which helps to improve the overall integration and reduce the overall volume.

[0038] Based on the above solution, in some embodiments, in combination with Figure 5 As shown, the heat dissipation component 2 includes a heat conductor 2-1, an outer panel 2-2, and a fan 2-3. The heat conductor 2-1 and the outer panel 2-2 can be fixedly spliced relative to each other to form a hollow inner cavity. The fan 2-3 is installed in the inner cavity formed by the splicing of the heat conductor 2-1 and the outer panel 2-2. The outer panel 2-2 is fixed to the rear end of the frame 1 and serves as the rear end face of the frame 1. The outer panel 2-2 is provided with an air flow channel 2-2-1 for the common air flow. The air inside and outside the heat dissipation component 2 can flow through the air flow channel 2-2-1. Driven by the fan 2-3, the outside air enters the inner cavity from a part of the air flow channel 2-2-1, flows through the fan 2-3, and then is discharged to the outside from a part of the air flow channel 2-2-1. When the air enters the inner cavity formed by the heat conductor 2-1 and the outer panel 2-2, it absorbs heat and takes the heat out to the outside for heat dissipation.

[0039] In combination with Figure 2 、 Figure 3 As shown, the front surface of the heat conductor 2-1 is used for thermally contacting the TR component 4, the signal processing module 5, and the power module 6. The heat generated by the TR component 4, the signal processing module 5, and the power module 6 is conducted to the heat conductor 2-1, and then conducted to the air flow guided by the fan 2-3. As the air flow flows, the heat is discharged outside the heat dissipation component 2. The heat conductor 2-1 and the heat generating components are stacked in sequence, and most of the heat is conducted to the heat dissipation component 2 by relying on the metal heat conduction method. The heat dissipation component 2 uses the fan 2-3 to introduce external cold air into the heat dissipation component 2 and take away the generated heat, achieving the purpose of cooling the radar.

[0040] In order to improve the heat dissipation efficiency, heat dissipation fins 2-4 for increasing the heat exchange area can be arranged in the inner cavity of the heat conductor 2-1. The heat dissipation fins 2-4 are plate-like structures perpendicular to the front end face of the heat conductor 2-1. The heat dissipation fins 2-4 are made of a metal material with a high thermal conductivity. The plate surface direction of the heat dissipation fins 2-4 is parallel to the air flow direction of the fan 2-3. The air flow generated by the fan 2-3 can pass through the gaps between the heat dissipation fins 2-4, and a larger contact area is formed between the air flow and the heat dissipation fins 2-4, improving the heat exchange efficiency.

[0041] There are two sets of heat dissipation fins 2-4 arranged in their extending direction, and the fan 2-3 is arranged between the two sets of heat dissipation fins 2-4. Combining Figure 5 As shown, there are two sets of left and right heat dissipation fins 2-4 respectively. Under the action of the fan 2-3, the air flow blows from the left to the right or from the right to the left. The fan 2-3 is located near the middle, and the lengths of the two sets of left and right heat dissipation fins 2-4 are approximately equal, so that the air flow can reach each position of the heat dissipation fins 2-4 more evenly, thereby forming a uniform cooling and heat dissipation effect.

[0042] Combining Figure 5 As shown, when installing the fan 2-3, fan brackets 2-5 can be fixedly arranged on the left and right sides respectively. The fan brackets 2-5 can be installed into the inner cavity of the heat conductor 2-1 by means of screw fixation. A row of fans 2-3 is supported by the fan brackets 2-5, and a uniform air flow is formed by the row of fans 2-3, so that each heat dissipation fin 2-4 in the row can be in contact with the air flow evenly for heat conduction.

[0043] The anti-drone radar system of the present invention uses the fan 2-3 to achieve active ventilation and cooling, but the external air flow can only enter the inner cavity of the heat dissipation component 2, and the air flow does not contact each device inside the system, so that the internal devices are kept in a waterproof and dustproof environment.

[0044] Combining Figure 1 、 Figure 2 、 Figure 5 As shown, the air flow channel 2-2-1 is a louver hole formed by sheet metal stamping. When in use, the outer panel 2-2 is placed vertically, and the opening of the louver hole faces downward. Through the sheet metal structure, the air flow does not perpendicular to the surface of the outer panel 2-2 when passing through the air flow channel 2-2-1, and the direction of the air flow changes by 90 degrees when passing through the air flow channel 2-2-1. The louver hole has a sheet metal structure to form a shield from above, which can not only provide good heat dissipation performance, but also effectively block the intrusion of external foreign objects and can block rainwater from entering the interior.

[0045] Combining Figure 1 As shown, an antenna cover 3-4 is covered and arranged at the front end of the waveguide slot antenna 3. The antenna cover 3-4 is fixed to the front end of the frame 1 by means of screws and the like. The antenna cover 3-4 is located at the front end of the waveguide slot antenna 3 to block the waveguide slot antenna 3. The antenna cover 3-4 serves as the front end face of the entire anti-drone radar system. The antenna cover 3-4 is used to protect the waveguide slot antenna 3 from the influence of environmental factors (such as rain, snow, dust, etc.), and at the same time minimize the influence on the electromagnetic wave transmission performance.

[0046] Combining Figure 1 、 Figure 2 、 Figure 5As shown in the figure, a number of screw holes are provided at the rear end face of the side wall of the frame 1. The outer panel 2-2 is fixed to the frame 1 by a number of screws. The edge of the outer panel 2-2 is flush with the edge of the frame 1 and presses against the rear end face of the frame 1. The cross-sectional area of the heat conductor 2-1 is smaller than the area of the outer panel 2-2. The heat conductor 2-1 can be completely placed inside the frame 1, and the surrounding side walls of the heat conductor 2-1 can form a heat conduction contact with the frame 1, so as to conduct part of the heat of the heat conductor 2-1 to the frame 1 and dissipate the heat to the outside through the frame 1. The frame 1 is made of heat-conducting metal and is directly in contact with the outside air, increasing the heat exchange area.

[0047] Thus, the heat dissipation efficiency of the entire anti-drone radar system is improved. The heat conductor 2-1 is fixed to the outer panel 2-2 by means of screws, etc. The outer panel 2-2 is used to carry the heat conductor 2-1, and no additional fixing structure needs to be provided between the heat conductor 2-1 and the frame 1.

[0048] Combined Figure 1 、 Figure 2 、 Figure 3 As shown in the figure, in some embodiments of the present invention, the TR component 4 is installed in the middle of the rear end face of the waveguide slot antenna 3, and the signal processing module 5 and the power supply module 6 are respectively installed on the left and right sides of the rear end face of the waveguide slot antenna 3. The TR component 4, the signal processing module 5 and the power supply module 6 are all located at the rear side of the waveguide slot antenna 3. The signal processing module 5, the TR component 4 and the power supply module 6 are arranged in sequence along the length direction of the waveguide slot antenna 3, and there is no overlap between them. The widths of the signal processing module 5, the TR component 4 and the power supply module 6 are approximately equal to the width of the waveguide slot antenna 3, so that the width is fully utilized.

[0049] Combined Figure 1 、 Figure 4 As shown in the figure, the working device further includes a sum-difference component 7 and a comprehensive channel module 8. The sum-difference component 7 is installed at the middle position of the rear end face of the TR component 4, and the comprehensive channel module 8 is stacked between the signal processing module 5 and the waveguide slot antenna 3. The waveguide slot antenna 3, the comprehensive channel module 8 and the signal processing module 5 are stacked in sequence from front to back; the heat generated by the comprehensive channel module 8 is small, so it does not need to be directly in heat conduction contact with the heat dissipation component 2. There is a signal transmission between the comprehensive channel module 8 and the signal processing module 5, so the two are stacked with each other.

[0050] The sum-difference component 7 protrudes from the surface of the TR component 4. In order to avoid the sum-difference component 7, a recessed area needs to be provided on the front end face of the heat conductor 2-1 for the sum-difference component 7 to be embedded. The sum-difference component 7 is in contact with the surface of the heat conductor 2-1 and can conduct heat.

[0051] Combined Figure 1As shown, due to the combinations formed by the stacking of the integrated channel module 8 and the signal processing module 5, and the combination formed by the stacking of the sum-difference component 7 and the TR component 4, and the different thicknesses (dimensions in the Y-axis direction) of the TR component 4 and the power module 6, the front end face of the heat conductor 2-1 is not a flat surface, but is set with uneven protrusions and depressions, so as to ensure that different positions on the front end face of the heat conductor 2-1 are in contact with the signal processing module 5, the TR component 4, the sum-difference component 7, and the power module 6 respectively.

[0052] The material of the waveguide slot antenna 3 is aluminum alloy, with a relatively large thermal conductivity and specific heat capacity. The peripheral side walls or the edges of the rear end face of the waveguide slot antenna 3 are kept in close contact with the frame 1. Part of the heat of the TR component 4, the integrated channel module 8, the power module 6, etc. is radiated or conducted to the frame 1 through the waveguide slot antenna 3, and the frame 1 exchanges heat with the air through convection.

[0053] The rear end of the waveguide slot antenna 3 is a receiving surface structure. The power module 6 and the integrated channel module 8 are fixed to the left and right sides of the rear end of the waveguide slot antenna 3 by means of screws. The signal processing module 5 is then stacked on the rear end face of the integrated channel module 8, and the heat dissipation component 2 is stacked on the rear end faces of the TR component 4, the signal processing module 5, and the power module 6. This solution forms a stacking and fixing method for each module, and each module is closely fitted, thus realizing a highly integrated assembly between the module components, making the anti-drone radar system small in volume and light in weight.

[0054] Combined Figure 5 As shown, the heat conductor 2-1 is a thin-shell structure. Correspondingly, the inner cavity surface of the heat conductor 2-1 is also a structure with uneven protrusions and depressions. The heat dissipation fins 2-4 are not of equal width either. The rear edge of the heat dissipation fins 2-4 close to the outer panel 2-2 is straight. The heat dissipation fins 2-4 are fixed to the front edge of the inner cavity of the heat conductor 2-1 and are adapted to the outer shape of the heat conductor 2-1. The width is larger in the part where the heat conductor 2-1 protrudes outward at the front end, which helps to increase the heat exchange area.

[0055] Combined Figure 1 As shown, in the normal usage state orientation, the wall surface of the frame 1 facing downwards is the bottom plate. The wave control component 9 is installed inside the bottom plate of the frame 1. The wave control component 9 is fixed to the inner cavity bottom plate of the frame 1 by means of screws for assembly. The wave control component 9 is a flat plate-like structure, and the length of the wave control component 9 is approximately equal to the length of the TR component 4; the waveguide slot antenna 3 is arranged perpendicular to the bottom plate of the frame 1, and a notch for avoiding the wave control component 9 is provided in the middle of the bottom edge of the waveguide slot antenna 3 for avoiding the wave control component 9.

[0056] The bottom plate of the frame 1 is provided with an external interface 1-1 for connection to the outside world. The external interface 1-1 is used for plugging with the signal lines from the outside world to achieve power supply and signal transmission. The external interface 1-1 is arranged at the bottom plate of the frame 1 and is located below during normal use, which can reduce the probability of rainwater ingress.

[0057] To achieve convenient assembly, the TR component 4, the signal processing module 5, the power supply module 6, and the integrated channel module 8 of the present invention are respectively fixed to the waveguide slot antenna 3 by means of screws, etc. Figure 1 As shown, a number of through holes for screws to pass through are provided at the edges and / or top corners of the TR component 4, the signal processing module 5, the power supply module 6, and the integrated channel module 8 respectively, and a number of matching studs are provided on the rear end face of the waveguide slot antenna 3. The screws pass through the through holes and are connected to the waveguide slot antenna 3.

[0058] The wave control component 9 is fixed to the frame 1 by means of screws, etc. A number of through holes are provided in the wave control component 9, and a number of screw holes are provided on the bottom plate of the frame 1. The screws pass through the wave control component 9 and fix it to the bottom plate of the frame 1.

[0059] The sum-difference component 7 is fixed to the TR component 4 by means of screws, etc. A number of through holes for screws to pass through are provided at the top corners and edges of the sum-difference component 7, and a number of threaded holes are provided on the rear end face of the TR component 4. The screws pass through the through holes and are screwed into the TR component 4.

[0060] The waveguide slot antenna 3 and the TR component 4 are connected by a waveguide port. When the waveguide slot antenna 3 and the TR component 4 are assembled in place with each other, the signal connection of the waveguide port can be achieved. The connection between the waveguide slot antenna 3 and the TR component 4 by the waveguide port ensures the efficient coupling between the TR component 4 and the waveguide slot antenna 3. Compared with a cable, the waveguide has lower transmission loss when operating in the high-frequency band, which is very beneficial for improving the overall performance of the system. By directly connecting the TR component and the antenna through the waveguide port, the physical structure of the system is simplified, which is convenient for installation and maintenance. The interface form between the TR component 4 and the sum-difference component 7 is SMP-J. When the TR component 4 and the sum-difference component 7 are assembled in place with each other, the signal connection of the SMP-J interface can be achieved. The SMP connector is a push-in and bite type plug-in connector, and the minimum size installation density can reach a center pitch of 4.3 mm for the connector, which is suitable for high-density blind mating. Through the signal transmission method of directly assembling and plugging between devices, the physical structure between components is simplified, which is easy to integrate and reduces the overall size and weight of the radar system.

[0061] Combined with Figure 6As shown, the waveguide slot antenna 3 includes an upper antenna cavity 3-1, a lower antenna cavity 3-2, and positioning pins 3-3. The two antenna components, the upper antenna cavity 3-1 and the lower antenna cavity 3-2, are processed by high-speed cutting technology. The lower antenna cavity 3-2 is provided with a number of positioning pins 3-3, and the upper antenna cavity 3-1 is provided with a number of positioning holes. The upper antenna cavity 3-1 and the lower antenna cavity 3-2 are positioned by the positioning pins 3-3. The precise positioning by the positioning pins 3-3 ensures the accurate relative position of the upper antenna cavity 3-1 and the lower antenna cavity 3-2. And they are fixedly assembled by means of screws etc. The upper antenna cavity 3-1 is fixed on the back of the lower antenna cavity 3-2 by means of screws etc.

[0062] The present invention uses a screw-fastening installation method. Compared with other high-cost fixing methods (such as welding, adhesives, etc.), it can not only significantly reduce the material cost, but also significantly reduce the manufacturing and assembly costs, ensuring the structural stability and reliability of the antenna.

[0063] In the present invention, through the staggered and stacked distribution among various components such as the frame 1, the heat dissipation component 2, the waveguide slot antenna 3, the TR component 4, the signal processing module 5, the power supply module 6, the sum-difference component 7, the integrated channel module 8, and the wave control component 9, heat is quickly conducted to the heat dissipation component 2 through heat conduction, and signal fast transmission is achieved through the way of joint plugging.

[0064] In order to make the heat dissipation of the main heat sources such as the TR component 4, the signal processing module 5, and the power supply module 6 stable, convex platforms are designed on the installation contact surface of the heat conductor 2-1, so that the TR component 4 is closely attached to the convex platform plane, and the signal processing module 5 and the power supply module 6 are respectively closely attached to the left and right plane sides of the convex platform. Most of the heat is quickly conducted to the heat conductor 2-1. At the same time, a large number of heat dissipation fins 2-4 are arranged inside the heat conductor 2-1 to increase the surface area and improve the chance of contact with air, thereby improving the heat dissipation efficiency. The fan 2-3 introduces external cold air into the heat dissipation component 2 and takes away the heat conducted to the heat conductor 2-1 through heat exchange. The external cold air enters the heat dissipation component 2 through the air flow channel 2-2-1 opened on the outer panel 2-2, and the hot air flows out from the heat dissipation holes on both sides of the outer panel 2-2 after heat exchange with the heat dissipation fins 2-4. Driven by the fan 2-3, the heat conductor 2-1, the fan 2-3, and the outer panel 2-2 form a unique concave-shaped air duct design. The louvered air flow channel 2-2-1 of the outer panel 2-2 can not only provide good heat dissipation performance, but also effectively block the intrusion of external foreign objects, ensuring good heat dissipation effect and protection performance of the radar system during operation.

[0065] The physical structure between the components of the anti-drone radar system of the present invention is simple, easy to integrate, reducing the overall size and weight of the radar system. The heat dissipation air duct is independently arranged, and the air flow does not need to pass through the internal components, with high heat dissipation efficiency and convenient maintenance. The whole machine is light in weight, convenient for erection and transportation, meeting the rapid erection requirements in different application scenarios.

[0066] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
