Description

Technical Field

[0001] The present invention relates to the technical field of drone countermeasures, and in particular to a multifunctional anti-drone detection and attack system. Background Art

[0002] At present, anti-UAV technology is mostly concentrated on vehicle-mounted or fixed platforms, usually using technologies such as microwave jammers, laser strike systems and high-energy electromagnetic weapons, which are suitable for point defense of important facilities or large-area coverage. However, they are large in size, complex to deploy, and lack flexibility. They cannot adapt to rapid response needs and cannot meet the needs of individual combat scenarios, especially when dealing with "low, slow and small" targets. Their efficiency is low, and most existing anti-UAV systems use a single signal jammer or a single physical interception method, lacking a systematic design that organically combines the two. A single signal jammer has limited effect against UAVs with strong jamming capabilities, making it difficult to achieve effective countermeasures. A single physical interception method is highly dependent on target positioning and tracking, lacks strike accuracy, and is prone to target slippage.

[0003] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a multifunctional anti-UAV detection and strike system is proposed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a multifunctional anti-UAV detection and strike system, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a multifunctional anti-UAV detection and strike system, comprising a radio detection subsystem, an optoelectronic detection subsystem, a micro-weapon subsystem and a control terminal, wherein the radio detection subsystem is connected to the control terminal via a wireless communication module, the optoelectronic detection subsystem is connected to the control terminal via a wireless communication module, the micro-weapon subsystem is connected to the control terminal via a wireless communication module, the control terminal is also connected to a radio countermeasure subsystem via a wireless communication module, and the radio countermeasure subsystem comprises an electromagnetic interference module and a satellite navigation system interference module, and the optoelectronic detection subsystem, the micro-weapon subsystem, the radio countermeasure subsystem and the wireless communication module are all mounted on the UAV body of the party.

[0006] Furthermore, the control terminal is connected to a data display module, and the data display module displays target information and strike status in real time through a graphical interface.

[0007] Furthermore, the radio detection subsystem is used to perform omnidirectional detection of target signals within the frequency band of 20MHz to 6GHz, and capture the characteristics of drone remote control signals and image transmission signals.

[0008] Furthermore, the radio detection subsystem is internally equipped with a direction finding algorithm, and the direction finding algorithm is used to calculate the moving direction of the target.

[0009] Furthermore, the optoelectronic detection subsystem is used to identify the type and location of the drone, and the micro-weapon subsystem is used to achieve target damage through projectile scattering, fragment attack and capture net interception according to the strike signal sent by the control terminal.

[0010] Furthermore, the control terminal is used to process data information of each subsystem, generate a comprehensive situation map, and execute uploading and distribution of task instructions.

[0011] Furthermore, the radio countermeasure subsystem interferes with the target UAV communication link and satellite navigation signal through the electromagnetic interference module and the satellite navigation system interference module.

[0012] Furthermore, a target movement prediction subsystem is provided inside the control terminal, and the target movement prediction subsystem is used to determine the position that the target can reach in each future time period according to the target movement direction calculated by the direction finding algorithm and the target movement speed.

[0013] Furthermore, the target movement prediction subsystem is connected to a self-control subsystem, and the self-control subsystem is connected to a movement control system of the own UAV.

[0014] Furthermore, the mobile control system is used to remotely control the movement of the own UAV, and the self-control subsystem is used to take over the mobile control system to automatically control the own UAV so that it reaches a designated location within a preset time period.

[0015] The present invention provides a multifunctional anti-UAV detection and strike system, which has the following beneficial effects: 1. This multifunctional anti-UAV detection and strike system adopts an integrated design and can be carried by a single soldier and quickly deployed. It covers a complete closed loop of detection, interference, identification and strike. It is suitable for single-soldier combat and flexible defense scenarios against "low, slow and small" UAV threats. It solves the technical problems of existing anti-UAV technologies such as single detection means, slow response speed, and low coordination efficiency caused by separation of system modules. It realizes efficient collaboration of the whole process of detection, interference, identification and physical strike to meet the needs of rapid deployment and flexible combat of single soldiers.

[0016] 2. When the multifunctional anti-UAV detection and strike system detects a target UAV and requires the operator to control the UAV to approach it, it will automatically plan the best interception path by calculating the target's moving direction and the position that can be reached in each future time period, and the operator does not need to manually operate the UAV until the UAV approaches the target UAV, and then the operator can manually operate it. This relieves the operator's workload so that the operator can concentrate on maintaining the best state to intercept the two UAVs when they meet. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1-Figure 5As shown, the present invention provides a technical solution: a multifunctional anti-UAV detection and strike system, including a radio detection subsystem, an optoelectronic detection subsystem, a micro-weapon subsystem and a control terminal, the radio detection subsystem is connected to the control terminal through a wireless communication module, the optoelectronic detection subsystem is connected to the control terminal through a wireless communication module, the micro-weapon subsystem is connected to the control terminal through a wireless communication module, the control terminal is also connected to a radio countermeasure subsystem through the wireless communication module, and the radio countermeasure subsystem includes an electromagnetic interference module and a satellite navigation system interference module, the optoelectronic detection subsystem, the micro-weapon subsystem, the radio countermeasure subsystem and the wireless communication module are all mounted on the UAV body of the party, the control terminal is connected to a data display module, and the data display module is connected to the control terminal through the wireless communication module. The graphical interface displays the target information and strike status in real time. The radio detection subsystem is used to perform omnidirectional detection of target signals in the frequency band of 20MHz to 6GHz, and capture the characteristics of the remote control signal and the image transmission signal of the drone. The radio detection subsystem is equipped with a direction finding algorithm, and the direction finding algorithm is used to calculate the moving direction of the target. The photoelectric detection subsystem is used to identify the type and position of the drone. The micro weapon subsystem is used to achieve target damage through projectile scattering, fragment attack and capture net interception according to the strike signal sent by the control terminal. The control terminal is used to process the data information of each subsystem, generate a comprehensive situation map, and perform the upload and distribution of task instructions. The radio countermeasure subsystem interferes with the communication link and satellite navigation signal of the target drone through the electromagnetic interference module and the satellite navigation system interference module; The specific operation is as follows: the radio detection subsystem is respectively mounted on the ground position and the own UAV according to the power range effect. The radio detection subsystem mounted on the ground is used to capture the signals of non-own UAVs within the monitoring range and their approximate positions in a large range. The own UAV uses its own radio detection subsystem to further retrieve the target signal and position based on the approximate position of the target after approaching the position. The radio detection subsystem performs omnidirectional detection of target signals in the frequency band of 20MHz to 6GHz, captures the characteristics of the UAV remote control signal and image transmission signal, and calculates the approximate direction of the target through the direction finding algorithm, so as to provide preliminary early warning and positioning, and provide support for subsequent interference and strike operations; When the friendly UAV reaches the approximate location and searches for the target signal and location, the friendly UAV approaches it and identifies the type and location of the UAV through the optoelectronic detection subsystem. The optoelectronic detection subsystem uses a CMOS high-definition camera and an uncooled infrared detector to efficiently identify and dynamically track the target, supporting target identification in daylight and low-light conditions. It has the ability to identify visible light within a range of 200 meters and infrared within a range of 50 meters, and can accurately lock the target, thereby achieving the effect of accurately identifying the type and location of the UAV and reducing misjudgment and missed judgment; When the target is determined to be a drone that is not on the whitelist, the radio countermeasure subsystem is used to interfere with the target drone's communication link and satellite navigation signal, which covers multiple frequency bands to force the target to lose control or return, thereby weakening the drone's control ability and reducing its threat. Since the UAV of the enemy will approach the target UAV, the enemy can freely choose whether to activate the micro-weapon subsystem while interfering. The micro-weapon subsystem uses a multi-level firepower strike strategy to achieve target damage through projectile scattering, fragment attack and capture net interception. The target is gradually hit through three stages: projectile scattering, fragment attack and capture net. The capture net covers a range of 1.5×1.5 meters, which effectively increases the damage rate and reduces the target's escape probability, thereby achieving signal interference while providing physical strike means to ensure that the target is completely intercepted or destroyed. The above operation process is displayed in real time through the data display module with a graphical interface to display target information and strike status, thus providing intuitive decision support for the operator; Based on the above description, the present invention adopts an integrated design, can be carried by a single soldier and deployed quickly, covering the complete closed loop of detection, interference, identification and attack, and is suitable for single-soldier combat and flexible defense scenarios against "low, slow and small" drone threats. It solves the technical problems existing in existing anti-UAV technologies, such as single detection means, slow response speed, and low coordination efficiency caused by separation of system modules, and realizes efficient collaboration of the entire process of detection, interference, identification and physical attack to meet the needs of rapid deployment and flexible combat of single soldiers.

[0020] like Figure 1-Figure 5 As shown, a target movement prediction subsystem is provided inside the control terminal, and the target movement prediction subsystem is used to determine the position that the target can reach in each future time period according to the target movement direction calculated by the direction finding algorithm and the target movement speed, and the target movement prediction subsystem is connected to the self-control subsystem, and the self-control subsystem is connected to the movement control system of the own UAV, the movement control system is used to remotely control the movement of the own UAV, and the self-control subsystem is used to take over the movement control system to automatically control the own UAV to make it reach the designated location within the preset time period; The specific operation is as follows: when the ground radio detection subsystem or the radio detection subsystem carried by the own UAV detects the target UAV signal, the direction finding algorithm calculates the approximate direction of the target, and at the same time, the control terminal measures the position that the target UAV will reach in the future time period based on the moving speed of the target UAV signal through the target movement prediction subsystem, and the own UAV obtains the ground terrain image in real time through the photoelectric detection subsystem after taking off and feeds it back to the control terminal. After obtaining the surrounding terrain image, the control terminal plans the best interception path based on the position of the target UAV in each future time period, so that the own UAV can intercept the target UAV at the preset position, and after planning the best interception path, the mobile control system connected to the own UAV is connected through the self-control subsystem, thereby taking over the mobile control system to automatically control the own UAV to make it reach the designated location within the preset time period; Based on the above description, when the present invention detects a target drone and requires the operator to control its own drone to approach it, it plans the best interception path by itself according to the target movement direction and the position that can be reached in each future time period, and there is no need for the operator to manually operate the drone movement until the own drone approaches the target drone and then switches to manual operation by the operator, thereby relieving the operator's workload so that the operator can concentrate on maintaining the best state when the two drones meet to intercept them. Example

[0021] Taking the temporary target defense scenario as an example, the specific system configuration is as follows: Equipment composition: Radio detection subsystem: used to detect and capture UAV signals. It is set in the ground defense position and in the UAV of the party. For the convenience of distinction, the radio detection subsystem set in the UAV of the party is referred to as the radio detection module below; Radio countermeasure subsystem: used to interfere with and cut off drone control signals; Photoelectric detection subsystem: used for target recognition and dynamic tracking; Micro-weapon subsystem: provides layer-by-layer firepower strikes, including projectiles and capture nets; Control terminal: coordinate various modules and display real-time data; Operation process: Deployment phase: A single soldier carries backpack equipment to a defense area (such as a temporary camp), places the backpack, and quickly deploys the ground equipment; The ground radio detection subsystem immediately begins signal detection, scanning the airspace for target drone signals; Detection phase: After detecting the drone signal, the operator confirms the target location and activates the radio countermeasure subsystem to implement signal interference to weaken or cut off the communication link of the target drone; Tracking phase: The radio detection subsystem captures the approximate position of the target and simultaneously activates the photoelectric detection subsystem onboard the drone to accurately track and image the target; Attack phase: The operator confirms the target threat level and activates the micro-weapon subsystem to destroy or forcefully land the target drone using projectiles and capture nets; Mission accomplished: The system provides real-time feedback on the strike results, and the operator recovers the drone equipment and ends the mission. Example

[0022] The operation scenario is to detect and counterattack in a designated area: Equipment composition: Radio detection subsystem carried by drones: used for high-altitude reconnaissance; Photoelectric detection subsystem: provides accurate image recognition and tracking; Micro weapon subsystem: intercepts targets by mounting projectiles and capturing nets; Data display module: used for real-time ground monitoring and operation command input; Operation process: Task launch: The soldier carries the equipment to the reconnaissance area, opens the backpack, releases the drone, and activates the aerial radio detection subsystem for reconnaissance; Reconnaissance phase: The drone is equipped with a radio detection module to capture drone communication signals in the area and display the approximate location of the target through the ground terminal; Locking target: The optoelectronic detection subsystem begins to identify and dynamically track the target drone, adjusts the focus in real time, and provides key information such as the target's direction and distance; Countermeasures: The operator activates the radio countermeasure subsystem to interfere with the target drone's communication signal. If the target is not forced to land, the micro-weapon strike subsystem is triggered to physically destroy it. Feedback and withdrawal: The ground terminal indicated that the strike was complete, and the operator recovered the drone and ground equipment, ending the reconnaissance mission.

[0023] In summary, when the multifunctional anti-UAV detection and strike system is used, the radio detection subsystem is first mounted on the ground position and the own UAV according to the power range effect. The radio detection subsystem mounted on the ground is used to capture the signals of non-own UAVs within the monitoring range and their approximate positions in a large range. The own UAV uses its own radio detection subsystem to further retrieve the target signal and position after approaching the position based on the approximate position of the target. The radio detection subsystem performs omnidirectional detection of target signals in the frequency band of 20MHz to 6GHz, captures the characteristics of the UAV remote control signal and the image transmission signal, and calculates the approximate direction of the target through the direction finding algorithm, so as to provide preliminary early warning and positioning, and provide support for subsequent interference and strike operations. When the friendly UAV reaches the approximate location and searches for the target signal and location, the friendly UAV approaches it and identifies the type and location of the UAV through the optoelectronic detection subsystem. The optoelectronic detection subsystem uses a CMOS high-definition camera and an uncooled infrared detector to efficiently identify and dynamically track the target, supporting target identification in daylight and low-light conditions. It has the ability to identify visible light within a range of 200 meters and infrared within a range of 50 meters, and can accurately lock the target, thereby achieving the effect of accurately identifying the type and location of the UAV and reducing misjudgment and missed judgment; When the target is determined to be a drone that is not on the whitelist, the radio countermeasure subsystem is used to interfere with the target drone's communication link and satellite navigation signal, which covers multiple frequency bands to force the target to lose control or return, thereby weakening the drone's control ability and reducing its threat. Since the UAV of the enemy will approach the target UAV, the enemy can freely choose whether to activate the micro-weapon subsystem while interfering. The micro-weapon subsystem uses a multi-level firepower strike strategy to achieve target damage through projectile scattering, fragment attack and capture net interception. The target is gradually hit through three stages: projectile scattering, fragment attack and capture net. The capture net covers a range of 1.5×1.5 meters, which effectively increases the damage rate and reduces the target's escape probability, thereby achieving signal interference while providing physical strike means to ensure that the target is completely intercepted or destroyed. The above operation process is displayed in real time through the data display module with a graphical interface to display target information and strike status, thus providing intuitive decision support for the operator; When the ground radio detection subsystem or the radio detection subsystem carried by the own UAV detects the target UAV signal, the direction-finding algorithm calculates the approximate direction of the target, and at the same time, the control terminal measures the position that the target UAV will reach in the future time period based on the moving speed of the target UAV signal through the target movement prediction subsystem. After taking off, the own UAV obtains the ground terrain image in real time through the photoelectric detection subsystem and feeds it back to the control terminal. After obtaining the surrounding terrain image, the control terminal plans the best interception path based on the position of the target UAV in each future time period, so that the own UAV can intercept the target UAV at a preset position. After planning the best interception path, the mobile control system of the own UAV is connected through the self-control subsystem, thereby taking over the mobile control system to automatically control the own UAV to reach the designated location within the preset time period.
