Description

Technical Field

[0001] This invention belongs to the field of airborne anti-drone technology, specifically relating to an airborne anti-drone system and its construction method, as well as related devices. Background Technology

[0002] Currently, unmanned equipment is widely used by state actors and non-state actors due to its low cost, easy accessibility and high degree of autonomy, posing a serious challenge to traditional defense systems and increasing the risk of miscalculation and loss of control. Therefore, it is necessary to improve the ability of existing defense systems to counter unmanned equipment.

[0003] Currently, in addition to using traditional conventional hard weapons (such as light weapons, anti-aircraft guns and anti-aircraft missiles) to launch munitions to counter drones, the anti-drone technologies of various countries around the world are becoming more novel and diversified, mainly including radio jamming deception, directed energy weapons, net capture and acoustic jamming, etc., and each method has different characteristics and effects.

[0004] Currently, most anti-unmanned aerial vehicle (AAV) system prototypes are primarily land-based or ship-based. These systems are typically mounted on platforms such as vehicles or ships, resulting in limited operational range. Increasing the operational range comes at the cost of making the AAV system larger, more expensive, and more complex, sacrificing its flexibility. Furthermore, AAV systems employing radio jamming, directed energy weapons, and acoustic interference often cause collateral damage or interference to surrounding friendly equipment, personnel, or facilities.

[0005] Moreover, current methods for constructing airborne anti-drone systems typically focus only on optimizing the system's strike capability, with relatively singular considerations. They fail to integrate with actual application scenarios and coordinate the design of multiple related factors, resulting in a mismatch between the system's strike capability and detection capability, as well as insufficient system reaction time in actual applications. Summary of the Invention

[0006] The purpose of this invention is to provide an airborne anti-drone system, its construction method, and related devices to address the problems in existing technologies where the consideration of factors is too singular, and the design fails to integrate multiple related factors with actual application scenarios, resulting in a mismatch between the system's strike capability and detection capability and insufficient system reaction time in actual applications.

The strike capability target model combines strike coverage, target flight speed, strike distance, effective action time, and the capabilities of the airborne anti-drone system itself to calculate the damage capability required to achieve an effective strike, and is used to characterize strike capability; the detection capability target model combines target flight speed, airborne anti-drone system response time, and strike distance to calculate detection distance, and is used to characterize detection capability. Based on the strike and detection capabilities of the airborne anti-drone system, the hardware configuration that can meet the strike and detection requirements of the airborne anti-drone system is determined, and used for the design of the airborne anti-drone system.

[0008] A further improvement of the present invention is that the defensive target characteristics include electromagnetic spectrum characteristics, radar characteristics, acoustic characteristics, and flight behavior characteristics.

[0009] A further improvement of this invention is that the expression for the strike capability target model is:

[0010] in, To achieve the destructive power required for effective strikes, For the capabilities of the airborne anti-drone system itself, For effective action time, In order to expand the coverage area, To determine the striking distance, The target flight speed.

[0011] A further improvement of this invention is that the expression for the detection capability target model is:

[0012] in, To detect distance, For the target flight speed, For the response time of the airborne anti-drone system, For the range of attack.

[0013] Secondly, the present invention provides an airborne anti-drone system construction system, characterized in that it includes: The target feature analysis module is used to acquire the features of the defense targets, analyze the features of the defense targets, and obtain the analysis results of the defense target features. The system capability determination module is used to determine the strike capability and detection capability of the airborne anti-drone system based on the analysis results of the defensive target characteristics, through the strike capability target model and the detection capability target model; The strike capability target model combines strike coverage, target flight speed, strike distance, effective action time, and the capabilities of the airborne anti-drone system itself to calculate the damage capability required to achieve an effective strike, and is used to characterize strike capability; the detection capability target model combines target flight speed, airborne anti-drone system response time, and strike distance to calculate detection distance, and is used to characterize detection capability. The hardware configuration determination module is used to determine the hardware configuration that can meet the strike capability and detection capability requirements of the airborne anti-drone system based on the strike capability and detection capability of the airborne anti-drone system, and is used for the design of the airborne anti-drone system.

[0014] Thirdly, the present invention provides an electronic device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the above-described method for constructing an airborne anti-drone system.

[0015] Fourthly, the present invention provides a storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of the above-described method for constructing an airborne anti-drone system.

[0016] Fifthly, the present invention provides an airborne anti-drone system designed using the airborne anti-drone system construction method described above.

[0017] A further improvement of the present invention is that it includes an air-to-air end and a ground-to-ground end; The airborne terminal includes a drone, a target attack module, and a first detection subsystem; the drone is used to carry a high-power microwave system to approach the target, the first detection subsystem is used to identify and track the target at close range after the drone approaches the target, and the target attack module is used to attack the target; The ground terminal includes a vehicle, a second detection subsystem, and a command and control subsystem. The vehicle is used to transport the airborne anti-UAV system. The second detection subsystem is used for long-range detection, positioning, and identification of targets. The command and control subsystem is used for fusing data from various sensors of the airborne anti-UAV system, situational analysis, threat assessment, strike guidance and control, and damage assessment. It is also used to monitor the health status of the airborne and ground-based equipment.

[0018] A further improvement of the present invention is that it also includes a power supply system for supplying power to the airborne anti-drone system.

[0019] Compared with the prior art, the present invention has the following beneficial effects: The proposed method for constructing an airborne anti-drone system first determines the strike and detection capabilities of the airborne anti-drone system based on the analysis results of the defense target characteristics, using strike capability target models and detection capability target models. Then, based on these strike and detection capabilities, it determines the hardware configuration that meets the requirements of the airborne anti-drone system's strike and detection capabilities. It is evident that this invention first determines the strike and detection capabilities of the airborne anti-drone system through the analysis results of the defense target characteristics, and then determines the hardware based on these capabilities. This approach avoids being limited to a single factor, effectively solving the problem in existing technologies where considerations are too simplistic and fail to consider multiple relevant factors in conjunction with actual application scenarios, leading to mismatches between strike and detection capabilities and insufficient system response time in practical applications. Furthermore, determining the strike and detection capabilities of the airborne anti-drone system based on the analysis results of the defense target characteristics, using strike and detection capability target models, not only avoids biases caused by relying on experience-based judgments but also ensures that the determination of the airborne anti-drone system's strike and detection capabilities is supported by objective data.

[0024] Example 3: The method for constructing an airborne anti-drone system according to the present invention includes the following steps: S1. Obtain the characteristics of the defense target and analyze the characteristics of the defense target to obtain the analysis results of the defense target characteristics.

[0025] The characteristics of the targets to be defended in this step include electromagnetic spectrum characteristics, radar characteristics, acoustic characteristics, and flight behavior characteristics.

[0026] S2. Based on the analysis results of the defensive target characteristics, the strike capability and detection capability of the airborne anti-drone system are determined through the strike capability target model and the detection capability target model; In this step, the strike capability target model combines the strike coverage area, target flight speed, strike distance, effective action time, and the capabilities of the airborne anti-drone system itself to calculate the damage capability required to achieve an effective strike, which is used to characterize the strike capability.

[0032] S3. Based on the strike capability and detection capability of the airborne anti-drone system, determine the hardware configuration that can meet the strike capability and detection capability requirements of the airborne anti-drone system, and use it to design the airborne anti-drone system.

[0033] Example 4: This embodiment discloses an airborne anti-drone system designed using the airborne anti-drone system construction method described above. This embodiment uses a vehicle-accompanying airborne anti-drone system as an example for illustration. The overall structural diagram of the vehicle-accompanying airborne anti-drone system of this invention is shown below. Figure 3 As shown, a schematic diagram of the vehicle-mounted airborne anti-drone system of the present invention is as follows. Figure 4 As shown, the vehicle-mounted anti-drone system of the present invention includes an airborne end and a ground end. The airborne end and the ground end are described in detail below: The airborne component includes a drone (also called drone platform 4), a target attack module, and a first detection subsystem (also called airborne detection subsystem 5). The drone is used to carry a high-power microwave system to approach the target. The first detection subsystem is used to identify and track the target at close range after the drone approaches the target. The target attack module is used to attack the target.

[0034] The ground-based system includes a vehicle (also called vehicle platform 3), a second detection subsystem (also called ground detection subsystem 2), and a command and control subsystem (in... Figure 3 (Represented by 1). The vehicle is used to transport the airborne anti-drone system, and the second detection subsystem is used for long-range detection, positioning, and identification of targets. The command and control subsystem is used for fusing data from various sensors of the airborne anti-drone system, situational analysis, threat assessment, strike guidance and control, and damage assessment. It is also used to monitor the health status of airborne and ground-based equipment.

[0035] In this embodiment, the target attack module can be a high-power microwave system (also called an airborne high-power microwave system 6), a laser system, a jamming and deception system, an acoustic jamming system, and a net capture system, or it can be a combination of multiple systems.

[0036] The target attack module in this embodiment is illustrated using a high-power microwave system as an example: A high-power microwave system comprises a pulsed power subsystem, a high-power microwave generation subsystem, and an antenna feed subsystem. The pulsed power subsystem powers the high-power microwave generation subsystem. The high-power microwave generation subsystem generates high-power microwaves. The antenna feed subsystem transmits and radiates the generated high-power microwaves.

[0037] In this embodiment, the pulse power subsystem, high-power microwave generation subsystem, and antenna feed subsystem are integrated and coaxially connected. This design allows the pulse power subsystem to be directly connected to the base of the high-power microwave generation subsystem, reducing the space occupied and the weight and number of structural auxiliary components.

[0038] In this embodiment, the high-power microwave generation subsystem is a permanent magnet packaged relativistic magnetron. Compared with other high-power microwave devices such as relativistic backwave tubes and virtual cathode oscillators, the permanent magnet packaged relativistic magnetron has the characteristics of small size, light weight and high conversion efficiency.

[0039] In this embodiment, the pulse power subsystem is a PFN-Marx hybrid pulse power source assembly. This design combines the stable forming capability of traditional PFN with the high boost characteristics of the Marx structure, achieving high amplitude and fast rise time pulse output within a relatively small volume. Furthermore, the PFN-Marx hybrid pulse power source assembly features a compact, high-energy-density, and lightweight design, including solid-state high-voltage energy storage, integrated capacitor array arrangement, and composite material support. This allows the pulse power subsystem to significantly reduce its overall weight while meeting the output power specifications of the airborne platform. Compared to traditional vehicle-mounted pulse sources, it achieves a substantial reduction in both mass and volume, thus meeting the stringent constraints of UAV deployment.

[0040] In this embodiment, the first detection subsystem is a photoelectric detection device.

[0041] The second detection subsystem in this embodiment is a radar detection device.

[0042] In this embodiment, the antenna feeder system also includes a mode converter, which is a coaxial insert-type mode converter. This design not only meets the requirement that the TM01-TE01 mode conversion efficiency is greater than 98% in the required frequency band, but also the coaxial insert-type mode converter is only 122mm long and weighs only 1kg.

[0043] The airborne anti-drone system of the present invention also includes a power supply system for supplying power to the airborne anti-drone system.

[0044] The working process of the airborne anti-drone system of the present invention is described below: The working process of the airborne anti-drone system of this invention is as follows: Figure 5 As shown, the workflow of the airborne anti-drone system of the present invention includes the following steps: When a target approaches, the second detection subsystem performs long-range detection, positioning, and identification of the target to obtain target information. The target information is transmitted to the command and control subsystem, which then performs fusion processing on the received target information, determines the target, and continuously tracks the target. The command and control subsystem controls the drone to approach the target, while the first detection subsystem identifies and tracks the target at close range and guides the antenna to aim at the target. The command and control subsystem generates high-power microwaves, and the control command subsystem controls the setting and transmission of microwave pulse parameters to irradiate the target. The command and control subsystem analyzes the target trajectory and attitude information detected by the detection subsystem to determine whether the target has been destroyed; If the target is destroyed, the drone returns to its origin; if the target is not destroyed, it continues to illuminate the target.

[0045] Example 5: The flowchart of the construction method of the airborne anti-drone system (hereinafter referred to as the system) of the present invention is as follows: Figure 6 As shown, this embodiment uses a high-power microwave system as an example to describe in detail the construction method of the airborne anti-drone system of the present invention: Step S1: Target Feature Analysis The high-power microwave system of this invention is mainly designed for targets including multi-rotor UAVs, fixed-wing UAVs, loitering munitions, and racing drones. The target feature analysis includes the analysis of the target's size, radar characteristics, and flight speed characteristics, providing a data foundation for target detection, identification, and tracking, as shown in Table 1.

[0046] Table 1. Key characteristics of typical UAV targets

[0047] Secondly, for the high-power microwave system of this invention, the high-power microwave effect threshold of the target is also an important part of target analysis. Unmanned aerial vehicles (UAVs) are typical targets exhibiting a combination of front-door and back-door coupling effects. Front-door coupling refers to high-power microwaves entering the electronic system through the UAV antenna and the transmission channel behind it, while back-door coupling refers to high-power microwaves entering the electronic system through gaps in the UAV's casing and cable connections. The coupling efficiency of a UAV to high-power microwaves is related to parameters such as microwave frequency, pulse width, repetition rate, incident angle, irradiation azimuth, and polarization. Different UAVs have different high-power microwave effect thresholds, and even for the same UAV model, the high-power microwave effect threshold varies depending on the UAV's irradiation attitude, polarization, and pulse characteristics. For the same high-power microwave system, different high-power microwave effect thresholds for the target result in different effective ranges. For a high-power microwave system with a feed power of 300MW and a C-band antenna gain of 30dB, the effective range for a target with an effect threshold of 40W / cm2 in the C-band is 243.4m, and the effective radius is 24.3m; the effective range for a target with an effect threshold of 100W / cm2 is 154m, and the effective radius is 15.3m. The actual values ​​are taken based on experience.

[0048] Step S2: Design of overall system functional indicators The main functions of the system are: to use unmanned helicopters (also called drones) equipped with a high-power microwave system to approach targets; and to integrate the unmanned helicopters with vehicle platforms to achieve mobile defensive deployment. This step mainly includes two dimensions: system detection capability design and system strike capability design. These two dimensions are described in detail below: A. Strike capability design Strike range, the capabilities of the airborne anti-drone system itself, and its effective duration. It conforms to the following model:

[0049] in, To achieve the destructive power required for effective strikes, For the capabilities of the airborne anti-drone system itself, For effective action time, In order to expand the coverage area, For the distance of the strike, The target flight speed.

[0050] For high-power microwave systems, antennas are used to radiate microwaves, thereby striking targets and increasing the strike coverage area. The effective range of an antenna in the far field region can be represented by its beamwidth. The relationship between the effective range of the antenna and its distance and beamwidth is as follows: Figure 7 As shown.

[0051] For high-power microwave systems, effective engagement is only possible when the target is within the antenna's radiation area (conical region). Furthermore, the target's dwell time within the engagement coverage area is related to its entry angle. Assuming the target flies tangentially across the antenna's radiation direction, based on the geometric relationships shown in the diagram, the effective engagement time... This can be expressed as:

[0052] Where V represents the target's flight speed, and regardless of the target UAV's attitude when entering the strike range, the effective duration of microwave action on the UAV is typically expected. The longer the better, that is, the wider the strike coverage. The larger the better, and the greater the target flight speed V, the more it is required. The larger the value, the longer the target remains within the strike range.

[0053] Typically, antenna gain G and beamwidth θ satisfy the following mathematical relationship:

[0054] Where G is the antenna gain and C is a constant, typically ranging from 15,000 to 40,000, and for parabolic surfaces, it can be 35,000. The antenna gain G is inversely proportional to the beamwidth θ.

[0055] The system can achieve an effective strike under the condition that E ≥ Emin, and the specific formula is as follows:

[0056] in, In order to expand the coverage area, For the distance of the strike, The capabilities of the airborne anti-drone system itself. It is related to the parameters of the airborne anti-drone system itself. Minimum damage factor This is a time parameter related to the target's flight speed.

[0057] For high-power microwave systems, the capabilities of airborne anti-drone systems themselves It can be expressed by the spatial power density formula: (5) Where S is the power density, P is the source power, G is the antenna gain (linear value), and R is the detection range. Based on an empirically chosen effect threshold of 100 W / cm², the system design is carried out, i.e., Emin = 100 W / cm². According to the condition that the system can achieve effective strike capability, E ≥ Emin, the capability of the airborne anti-drone system is expressed as:

[0058] As shown in Formula 6, given the power density S and detection distance R, the source power P is inversely proportional to the antenna gain G. When designing a high-power microwave system, it is desirable for the beamwidth to cover a wider range to increase the system's effective radius. However, for the antenna gain G, the larger the beamwidth, the smaller the gain G. The decrease in gain requires increasing the source power to compensate. The source power is generally proportional to the system weight. Increasing the source power will increase the system weight and make the UAV's payload bulky. Therefore, a balance needs to be struck between the two during the design process.

[0059] When designing a high-power microwave system, considering the requirement for lightweight design, the source power P=300MW, power density S=100W / cm2, and system operating frequency of 5.8GHz were selected for the design. Based on the above formula, the relationship between antenna gain and beamwidth under different antenna apertures is shown in Table 2.

[0060] Table 2. Estimation of Antenna Gain and Beamwidth Relationship under Different Antenna Apertures

[0061] After evaluating the antenna aperture, gain, beamwidth, and weight, an antenna aperture of 0.25m and an antenna gain of G=21.7dB were selected for the design, resulting in a system operating distance of R=60m. The system design was then carried out based on these specifications.

[0062] B. Detection Capability Design The primary requirement for detection capability design is that the detection system can accurately detect and identify targets such as multi-rotor UAVs, fixed-wing UAVs, loitering munitions, and racing drones. The calculation formula for detection is as follows:

[0063] in, To detect distance, For the target flight speed, For the response time of the airborne anti-drone system, For the range of attack.

[0064] According to the strike range of the airborne anti-drone system =60m, taking the target's maximum flight speed as 80m / s, and the airborne anti-drone system response time T=60s, the detection range is obtained. ≥4860m≈5km.

[0065] Step S3: Design of the hardware platform (or hardware configuration) for the airborne anti-drone system (also called anti-drone system). Based on the strike and detection capabilities of airborne anti-drone systems, the hardware configuration that can meet the requirements of these capabilities is determined. Specifically, the detection system capabilities and hardware selection in the anti-drone system are determined according to the detection capability indicators (also called detection capability), the anti-drone system hardware (such as high-power microwave systems) is determined according to the strike capability indicators (also called strike capability), and the hardware capabilities of each part of the anti-drone system (such as laser, net capture, and acoustic jamming) are determined according to the effective range.

[0066] The following is a detailed description of the hardware configuration that meets the strike and detection requirements of an airborne anti-drone system: The airborne anti-drone system consists of two main parts: the airborne end and the ground end. The airborne end comprises an unmanned helicopter platform (also called a drone platform 4), an airborne detection subsystem, a pulse power subsystem, a high-power microwave generation subsystem, and an antenna feed subsystem. The ground end comprises a ground detection subsystem, a command and control subsystem, a power supply and distribution system, and a vehicle platform. The airborne end and the ground end are described in detail below: a. Air terminal Unmanned helicopter platform: The unmanned helicopter platform is used to carry high-power microwave system payloads to approach targets. When the high-power equipment is working, it will cause electromagnetic interference to the UAV's own communication and flight. When designing the system and its components, electromagnetic compatibility design technologies such as electromagnetic shielding, filtering, and grounding are used to carry out high electromagnetic compatibility design for key components such as non-control, data link, and power supply on the unmanned helicopter platform, effectively blocking the electromagnetic interference generated by the high-power microwave system itself. At the same time, the system layout takes into account the impact of system counterweight on the UAV helicopter's mobility.

[0067] Airborne Detection Subsystem: The airborne detection subsystem is an optoelectronic detection device used for close-range optoelectronic visual identification and tracking of targets after the UAV approaches the target.

[0068] The high-power microwave system is the core component of the entire vehicle-mounted anti-drone system. It consists of a pulse power subsystem, a high-power microwave generation subsystem, and an antenna feed subsystem. These subsystems are connected coaxially in sequence. The payload components of each subsystem are designed with miniaturization and weight reduction in mind to ensure the system's mobility and safety. A schematic diagram of the high-power microwave system is shown below. Figure 8 As shown.

[0069] The pulse power subsystem is charged by a high-voltage charging power supply and triggers discharge to generate high-voltage pulses, which power the high-power microwave generation subsystem. The high-power microwave generation subsystem is the core of the entire system; the high-power microwave generating device converts the electrical pulses generated by the pulse power drive source into high-power microwave output. The vacuum unit maintains a high vacuum level inside the device, ensuring stable operation at the repetition rate. The antenna feed subsystem transmits the high-power microwaves generated by the high-power microwave generation subsystem to the radiating antenna through a waveguide, achieving focused energy targeting.

[0070] b. Ground end The ground-based system is primarily mounted on a vehicle platform, which consists of the vehicle platform, storage and transportation container, UAV take-off and landing platform, and integrated support equipment. It mainly enables the mobile, accompanying anti-UAV defense transport deployment and support of airborne anti-UAV systems. The storage and transportation container is used for storing and securing the UAV helicopter platform and support equipment, and is transported over long distances via the vehicle platform. The integrated support equipment, designed to ensure flight operations, mainly includes commonly used field equipment such as ground operation facilities, refueling equipment, testing and maintenance equipment, including ground transfer equipment, ground power supply equipment, fuel dumping equipment, tools, instruments, and spare parts, for the daily use, maintenance, repair, and upkeep of the UAV helicopter.

[0071] The ground detection subsystem is a radar detection device used for long-range detection, location, and identification of targets.

[0072] The main function of the power supply and distribution system is to ensure the power supply needs of the vehicle-accompanying airborne anti-drone system. The onboard payload adopts two modes: direct charging and battery swapping. The ground support vehicle is equipped with a charger and a backup battery, and a small diesel generator is also equipped to provide initial energy for the system.

[0073] The command and control subsystem includes functions such as overall system situational surveillance, command and control, intelligence analysis, comprehensive situational awareness display, equipment health monitoring, and overall system power management. It mainly consists of equipment such as a flight control terminal, an optoelectronic control terminal, positioning and orientation devices, alarm devices, radar terminal software, and a strike decision system. The flight control terminal is used to control the UAV, including its azimuth, speed, altitude, and attitude. The optoelectronic control terminal is used to obtain visual images and video information of the target, continuously visually detecting and tracking the target. The radar control terminal is used for ground-based detection of the surrounding airspace to defend against enemy UAV attacks. When an enemy UAV enters the defense range, it triggers the alarm device to alert ground terminal control personnel and reports the target information to the command and control system. The positioning and orientation devices include ground-based and airborne positioning and orientation. Ground-based positioning and orientation can obtain precise location information of the incoming UAV and control friendly UAVs to reach the target area for interception. The strike decision system is used for the final decision on handling incoming targets and setting corresponding strike strategies. A schematic diagram of the command and control subsystem is shown below. Figure 9 As shown.

[0074] Step S4: System Workflow Design The workflow of the vehicle-accompanied airborne anti-drone system proposed in this invention is as follows: When a target approaches, the second detection subsystem performs long-range detection, positioning, and identification of the target to obtain target information. The target information is transmitted to the command and control subsystem, which then performs fusion processing on the received target information, determines the target, and continuously tracks the target. The command and control subsystem controls the drone to approach the target, while the first detection subsystem identifies and tracks the target at close range and guides the antenna to aim at the target.
