[0025] S3. Calculate the azimuth angle between the target drone and any drone in the whitelist of drones. If the azimuth angle is less than half of the beam angle of the fixed jamming device, proceed to step S4; otherwise, proceed to step S5.

[0026] S4.

[0042] Figure 2 This is a schematic diagram of a drone detection and countermeasure method in an embodiment of the present invention. Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0044] like Figure 1 As shown, the present invention provides a drone detection and countermeasure system, including a radio detection and jamming device, a display and control device, and a fixed jamming device;

[0045] The radio detection and jamming equipment is used to detect unmanned aerial vehicles (UAVs). After detecting a UAV, it sends UAV information to a display and control device and responds to a precision strike control command issued by the display and control device. It generates jamming signals for interfering with the communication frequency band of the target UAV and transmits the jamming signals to the target UAV to achieve precision strike. The UAV information includes at least the UAV's communication frequency band information and location information. In this invention, the radio detection and jamming equipment has both detection and jamming functions. It is linked with the display and control device. After detecting the location information of the target UAV, it responds to the precision strike control command issued by the display and control device, generates and transmits jamming signals for interfering with the communication frequency band of the target UAV, and transmits jamming signals to a specified narrow frequency band range to achieve precision strike against the target UAV.

[0046] The detection part of the radio detection and jamming device in this invention uses radio protocol cracking, direction finding and positioning, and weak signal identification technologies, while the jamming part uses built-in advanced algorithms to analyze the radio signals received by the antenna. Combined with real-time on-site data and protocol cracking database, it can detect and defend against various drones based on radio frequency flight control, thus achieving integrated detection and jamming.

[0047] The display and control device is used to determine the target UAV after receiving UAV information, and generate a precision strike control command based on the target UAV's location information and send it to the radio detection and jamming device, or generate a directional jamming control command and send it to the fixed jamming device; in this invention, the display and control device is used to control the radio detection and jamming device and the fixed jamming device to generate and send jamming signals.

[0048] Fixed jamming equipment is used to respond to directional jamming control commands issued by display and control equipment, generate and transmit directional jamming signals, and conduct directional jamming attacks on target drones. In this invention, the fixed drone jamming equipment only has jamming function and is linked with display and control equipment. After detecting the location information of the target drone, it responds to the directional jamming control commands issued by display and control equipment, generates and transmits directional jamming signals, and concentrates the transmission of jamming signals to a designated small area to enhance the attack effect and reduce interference to communication equipment in the area.

[0049] After detecting a drone, the radio detection and jamming equipment sends the drone's information to the display and control equipment. Upon receiving the drone's information (at least its communication frequency band and location information), the display and control equipment identifies the target drone and, based on its location information, generates a precision strike control command and sends it to the radio detection and jamming equipment, or generates a directional jamming control command and sends it to the fixed jamming equipment. The radio detection and jamming equipment or the fixed jamming equipment then generates and transmits corresponding jamming signals to precisely strike or directionally jam the target drone's communication frequency band.

[0050] In some implementations, such as Figure 1 As shown, the radio detection and jamming equipment includes a detection antenna, a signal processing unit, a receiving channel unit, an antenna power amplifier unit, and a jamming antenna;

[0051] The detection antenna is used to receive radio signals to detect drones and to send echo data to the signal processing unit through the receiving channel unit;

[0052] The signal processing unit is used to process echo data, determine the azimuth information and communication frequency band information of the UAV, process the precision strike control commands issued by the display and control equipment, determine the frequency band and power of the interference signal, and send the corresponding commands to the antenna power amplifier unit.

[0053] The antenna power amplifier unit is used to respond to the instructions issued by the signal processing unit, generate interference signals in a specified frequency band, and transmit them through the interference antenna.

[0054] In radio detection and jamming equipment, the detection antenna is used to receive radio signals to detect drones, and the jamming antenna is used to transmit radio signals to interfere with drones. The antenna system composed of the detection antenna and the jamming antenna consists of a log-periodic antenna array. In order to ensure the antenna gain for receiving direction-finding signals, the log-periodic antenna array operates at 2.4 GHz and 5.8 GHz. By using multiple antenna array elements, the same radio electromagnetic wave signal in space is induced into wired signals with different amplitudes and phases.

[0055] The core receiver of the receiving channel unit is the LK-H100 broadband receiver, which is a radio monitoring device operating in the frequency range of 9kHz to 6GHz. It adopts a superheterodyne triple conversion system with an intermediate frequency bandwidth of 27MHz. It is mainly used to search, monitor and analyze wireless signals and has high receiving sensitivity.

[0056] The antenna power amplifier unit enables the switching between low-end and high-end antenna channels, realizes the switching selection of direction-finding antenna array signals, and sends the routed signals to the down-conversion equipment. The RF switch matrix is ​​the core control device for signal exchange between various RF front-end devices. It receives instructions from the signal processing unit and outputs different control signals in different modes to implement signal selection and switching control for the external antenna system.

[0057] The signal processing unit has two built-in SOM boards to drive the antenna to receive radio signals from 70MHz to 6GHz. After the received signals are amplified by the LNA, the built-in algorithm performs protocol cracking and intelligent analysis on the signals.

[0058] In some implementations, such as Figure 1 As shown, the fixed jamming device includes a communication module, a power amplifier module, and a two-dimensional turntable;

[0059] The communication module is used to exchange information with the display and control equipment, and to send control commands to the power amplifier module and the 2D turntable;

[0060] The power amplifier module is used to transmit directional jamming signals. The power amplifier module operates in the 0.4GHz to 6GHz frequency band, and the jamming signal transmission frequencies include: 433±5MHz, 840MHz to 845MHz, 902MHz to 928MHz, 1430MHz to 1485MHz, 2400MHz to 2485MHz, 5150MHz to 5250MHz, and 5720MHz to 5850MHz, which can cover the entire communication frequency band of the UAV. The jamming signal transmission frequency can be selected to be enabled according to the communication frequency band information in the UAV information.

[0061] The two-dimensional turntable is used to carry the power amplifier module and control the transmission direction of the directional jamming signal. The two-dimensional turntable controls the direction of the jamming signal transmitted by the power amplifier module by rotating in two directions: azimuth and pitch, and sends real-time azimuth and pitch data to the communication module. The rotation of the two-dimensional turntable can realize the transmission of directional jamming signals in all directions of 360°.

[0062] In some implementations, the drone detection and countermeasure system also includes a network connection device; the display and control device is connected to the radio detection and jamming device and the fixed jamming device via the network connection device.

[0063] In some implementations, the drone detection and countermeasure system also includes a server;

[0064] The server connects to the display and control equipment and the radio detection and jamming equipment via network connection devices.

[0065] This invention enables the connection between the display and control device and the server, the display and control device and the fixed jamming device, and the server and the radio detection and jamming device through network connection devices, and conducts information exchange through the network port; through the server, in addition to the user who controls the display and control device, other users can also obtain the detection information of the target UAV by the radio detection and jamming device, and at the same time, the detection information of the target UAV can also be stored locally on the server.

[0066] In some implementations, the operating modes of the display and control device include unattended mode and manual control mode.

[0067] This invention enables the control of radio detection jamming devices and fixed UAV jamming devices through a display and control device. The display and control device operates in two modes: unattended mode and manual control mode. In manual control mode, the display and control computer does not actively issue precision strike control commands and directional jamming control commands based on UAV information. Through manual control, all precision strike control commands and directional jamming control commands that can be issued in unattended mode can be issued. Specifically, it controls the azimuth, pitch, and jamming signal transmission status of the fixed UAV jamming device, and controls the addition and removal of whitelists, the jamming of designated UAVs, and the jamming of designated communication frequency bands of the radio detection jamming device.

[0068] The general application environment of the UAV detection and countermeasure system of this invention is regional control at fixed locations. In order to enhance the UAV detection and countermeasure effect, the front-end equipment (radio detection and jamming equipment, fixed UAV jamming equipment) is set up at a high place and needs to be connected to the back-end equipment (server, display and control computer) through network connection equipment. The network connection adopts a local area network. The back-end equipment is placed within a few kilometers and can remotely control the front-end equipment.

[0069] like Figure 2 As shown, the present invention also provides a method for detecting and countering unmanned aerial vehicles (UAVs), which is implemented using the UAV detection and countermeasures system of the first aspect described above, and includes the following steps:

[0070] S1. Enable unattended operation mode and set the interference cycle;

[0071] S2. Detect drones using radio detection and jamming equipment, and send the detected drone information to the display and control equipment to generate a whitelist of drones and a list of drones to be attacked. Set the drone ranked first in the list of drones to be attacked as the target drone. It should be noted that the whitelist of drones is the list of friendly drones.

[0072] S3. Calculate the azimuth angle between the target drone and any drone in the whitelist of drones. If the azimuth angle is less than half of the beam angle of the fixed jamming device, proceed to step S4; otherwise, proceed to step S5.

[0073] S4. Send a precision strike control command to the radio detection and jamming device through the display and control device, instructing the radio detection and jamming device to generate and transmit corresponding jamming signals to precisely strike the communication frequency band of the target UAV. After one jamming cycle, stop sending the precision strike control command and execute step S6.

[0074] S5. Send a directional jamming control command to the fixed jamming device through the display and control device, instructing the fixed jamming device to generate and emit directional jamming signals to carry out directional jamming attacks on the target UAV. After one jamming cycle, stop sending the directional jamming control command and execute step S6.

[0075] S6. Mark the drones that are being interfered with;

[0076] S7. If the unattended mode ends, proceed to step S8; otherwise, return to step S2.

[0077] S8. Exit unattended mode, stop sending all interference signals, and enter manual control mode.

[0078] This invention's drone detection and countermeasure method can be implemented in both unattended and manual control modes. In unattended mode, after detecting a drone using a radio detection and jamming device, the detected drone information is sent to a display and control device. Upon receiving the drone information (at least its communication frequency band and azimuth information), the display and control device marks the drone, generating a whitelist of drones. Drones not on the whitelist are then sorted to generate a list of drones to be attacked, and the drone ranked first in the list is identified as the target drone. When the number of drones in the whitelist is not zero, the azimuth angle between the target drone and any drone in the whitelist is calculated based on the target drone's azimuth information. The azimuth angle between the target drone and any drone in the whitelist is then determined. The azimuth angle between drones in the single list determines the jamming method. When the azimuth angle between the target drone and any drone in the whitelist is less than half the beam angle of the fixed jamming device, in order to avoid affecting drones in the whitelist, the display and control device sends a precision strike command to the radio detection and jamming device targeting the target drone. The radio detection and jamming device then generates and transmits jamming signals to interfere with the communication frequency band of the target drone, thereby achieving a precision strike against the target drone. When the azimuth angle between the target drone and any drone in the whitelist is greater than half the beam angle of the fixed jamming device, the display and control device sends a directional jamming command to the fixed jamming device targeting the target drone. The fixed jamming device then generates and directs the jamming signals, thereby achieving directional jamming against the target drone.

[0079] In some implementations, the whitelist of drones and the list of drones to be targeted are generated in the following way:

[0080] The display and control equipment marks its own drones based on the detected drone information and generates a whitelist of drones.

[0081] Sort the drones not on the whitelist to generate a list of drones to be targeted.

[0082] Furthermore, the drones in the list to be attacked in this invention are sorted according to the order in which they appeared, with the earlier ones appearing first and the later ones appearing last. However, this is not limited to this. They can also be sorted according to the size of the azimuth angle between the drones to be attacked and the drones in the whitelist of drones, with the smaller azimuth angle appearing first and the larger azimuth angle appearing last.

[0083] In some implementations, the radio detection jamming device generates and transmits corresponding jamming signals including:

[0084] Based on the target drone's communication frequency band, generate and transmit a narrowband, low-power jamming signal targeting the target drone's communication frequency band.

[0085] In some implementations, the fixed jamming device generates and transmits directional jamming signals including:

[0086] Based on the target drone's communication frequency band, a wideband, high-power jamming signal covering the target drone's communication frequency band is generated and transmitted towards the target drone.

[0087] To avoid affecting whitelisted drones during the jamming of a target drone, this invention determines the jamming method based on the azimuth angle between the target drone and any drone in the whitelist. When the azimuth angle between the target drone and any drone in the whitelist is less than half the beam angle of the fixed jamming device, the radio detection jamming device generates and transmits jamming signals that interfere with the target drone's communication frequency band, sending jamming signals to drones within a specified narrow frequency band range to achieve precise strikes against the target drone. Otherwise, the fixed jamming device generates and transmits wideband, high-power directional jamming signals covering the target drone's communication frequency band, concentrating the jamming signals to a specified smaller area.

[0088] The drone detection and countermeasure method provided by this invention has no active electromagnetic radiation during the early warning and detection phase, and the entire detection and countermeasure process has very little impact on communication equipment within the control area. It has unattended operation capability and can automatically complete the detection and strike of multiple target drones in the area without human intervention. In addition, the drone detection and countermeasure method provided by this invention can add friendly drones to a whitelist, enabling the identification and protection of friendly drones during the automatic strike of target drones.

[0089] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
