[0017] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0018] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0019] In response to the reconnaissance, sabotage and attack activities of drones in target areas, existing technologies often employ countermeasures such as navigation deception. This method simulates and transmits false satellite navigation signals to mislead the drone's flight control system, causing it to deviate from the preset flight path, thereby achieving non-contact countermeasures.
[0020] However, such decoy systems lack accurate real-time positioning and continuous tracking of the target drone's location, making it difficult to dynamically generate an induction trajectory that matches the real airspace conditions. This results in low fault tolerance and poor adaptability in the induction process, low overall countermeasure efficiency, and difficulty in dealing with highly dynamic drone targets.
[0021] To address the aforementioned issues, this application provides an intelligent countermeasure system, method, device, and medium for unmanned aerial vehicles (UAVs). The solution described in this application is detailed below.
[0022] Figure 1 The present application provides a structural block diagram of an intelligent anti-drone system 100, which may include: a detection and identification module 110, a positioning and direction finding module 120, a signal jamming module 130, and a path guidance module 140 connected in pairs; the detection and identification module 110 is used to determine whether there is an unmanned aerial vehicle (UAV) in the target area; the positioning and direction finding module 120 is used to determine the real-time position of the UAV; the signal jamming module 130 is used to jam the communication link between the UAV and the corresponding controller and the UAV's positioning signal based on the real-time position; the path guidance module 140 is used to transmit an inducement signal to the UAV based on the real-time position and generate a dynamic inducement path, wherein the dynamic inducement path is used to guide the UAV to leave the target area when the UAV receives the inducement signal.
[0023] It should be noted that the UAV's data link includes core components such as a radio frequency transceiver, a modem module, and an antenna. The communication stability of the data link determines whether the UAV can fly safely in the target area. In this embodiment, the signal jamming module 130 can interfere with the UAV's data link, preventing the UAV from transmitting effective information with the remote control device and interfering with the remote control device's control of the UAV.
[0024] It is understood that the interference mentioned in this embodiment refers to communication interference with data links. Communication interference is a general term for electronic attack actions aimed at disrupting or interfering with the information (image or data) transmission process of local communication systems. In particular, a communication interference system can disrupt the radio communication process by emitting a specific form of electromagnetic signal associated with the communication signal, thereby causing communication paralysis.
[0025] In the specific implementation process, the detection and identification module 110 can scan the frequency band from 300MHz to 6GHz in the target area using spectrum sensing technology to determine whether there is a drone signal in the target area. If there is a drone signal, the module will compare the signal characteristics of the drone signal with the built-in artificial intelligence classification algorithm and drone model library (including hundreds of models such as DJI, Autel, Dahua, and EHang) to determine the specific model of the drone.
[0026] The positioning and direction finding module 120 is connected to the detection and identification module 110 and receives the UAV signal output by the detection and identification module 110 to determine the UAV's real-time position. Specifically, the positioning and direction finding module 120 uses two or more detection devices and employs a cross-positioning algorithm (when two devices are deployed) or a TDOA (Time Difference of Arrival) positioning algorithm (when three or more devices are deployed) to accurately determine the UAV's real-time position and simultaneously calculate the position of the UAV pilot (i.e., the UAV remote controller operator).
[0027] The signal jamming module 130 connects the detection and identification module 110 and the positioning and direction finding module 120. Based on the real-time position of the UAV provided by the positioning and direction finding module 120, the signal jamming module 130 can precisely jam the communication link between the UAV and its corresponding controller, as well as the UAV's positioning signal. Specifically, the signal jamming module 130 includes a digital baseband unit and an analog radio frequency unit. The digital baseband unit can detect and synchronize UAV signals and generate jamming signals based on the UAV's real-time position. The analog radio frequency unit can convert the jamming signal to the target frequency band and finally transmit it through an antenna to jam the communication link (uplink) between the UAV and its corresponding controller, as well as the UAV's positioning signal.
[0028] The path guidance module 140 is connected to the signal jamming module 130. The path guidance module 140 can generate and transmit an inducement signal, i.e., a false navigation signal, based on the real-time position of the UAV. In addition, the path guidance module 140 can also calculate the forwarding delay of the inducement signal, causing the UAV navigation system to calculate an incorrect self-position, thereby generating a dynamic inducement path to guide the UAV to a preset safe area.
[0029] In one embodiment, the detection and identification module 110 can identify the model information of the UAV, which is transmitted in real time to the positioning and direction finding module 120 and the signal jamming module 130. The positioning and direction finding module 120 can use the model information to determine the communication frequency band and frequency hopping mode of the UAV model, thereby calibrating the scanning parameters and improving the positioning speed and positioning accuracy.
[0030] Specifically, the detection and identification module 110 includes a spectrum sensing unit and an identity recognition unit. The spectrum sensing unit is equipped with a wideband radio frequency receiver and can identify the radio frequency signals of drones in the target area. The identity recognition unit is equipped with a high-performance embedded DSP as the core processor, which contains a drone model library. It can use artificial intelligence classification algorithms to compare and match signal features to obtain the specific model of the drone.
[0031] In one embodiment, the location information of the drone pilot calculated by the positioning and direction-finding module 120 is uploaded to the system terminal. The system may also include a pilot processing module, which can allocate resources and process the pilot based on the location information. It is understood that the pilot processing module can be a software logic module or it can be linked with physical security forces.
[0032] In one embodiment, the signal interference module 130 is configured with a first signal generator and a power amplifier. The first signal generator and the power amplifier can generate various forms of interference waveforms according to interference guidance parameters, thus obtaining an interference signal. It should be noted that the first signal generator is a DSP+FPGA architecture, capable of generating baseband signals of arbitrary waveforms, such as linearly swept signals. The power amplifier then amplifies this baseband signal to form the interference signal. It can be understood that the power amplifier can amplify a low-power baseband signal to obtain an interference signal that meets the interference requirements.
[0033] In another embodiment, the signal jamming module 130 may include a digital baseband unit and an analog radio frequency unit. The digital baseband unit may adopt a DSP+FPGA architecture. The DSP is the core and can communicate with the host computer for signal detection of the UAV remote control link. The FPGA can be used for high-speed signal processing, that is, to generate jamming signals in real time in conjunction with the DSP.
[0034] It should be noted that the interference signals generated by the digital baseband unit can have various signal patterns, including but not limited to linear sweep signals and AWGN (additive white Gaussian noise) signals.
[0035] The analog radio frequency unit is divided into a receiving path and a transmitting path. The receiving path includes S-band downconversion (processing 2-4GHz signals) and C-band downconversion (processing 4-8GHz signals), and consists of filters, low-noise amplifiers (LNAs), mixers, local oscillator modules, and controllable digital attenuators, which can downconvert radio frequency signals to 375MHz analog intermediate frequency signals for output. The transmitting path consists of an upconversion module and a power amplifier, which can upconvert interference signals output by the digital baseband unit to the target frequency band and amplify them.
[0036] It is understandable that the analog radio frequency unit can convert the interference signal generated by the digital baseband unit to the target frequency band, thus obtaining the final interference signal. This final interference signal can then be used to interfere with the communication link between the UAV and the corresponding controller, as well as the UAV's positioning signal.
[0037] In one embodiment, the path guidance module 140 includes an inducement signal generation unit and an inducement path generation unit. The path guidance module 140 is configured with a second signal generator. The second signal generator has the same internal structure as the first signal generator. The inducement signal generation unit can generate an inducement signal based on GPS spoofing.
[0038] GPS spoofing refers to an attacker actively transmitting false navigation signals that resemble genuine GPS signals, causing the drone to mistakenly believe the false navigation signals originate from real satellites, thereby calculating incorrect position, speed, or time. It is understood that this embodiment generates a misleading signal based on GPS spoofing, which can cause the drone's receiving terminal to generate incorrect positioning information.
[0039] Specifically, the induced signal generation unit has a built-in GPS receiver. After receiving visible satellite signals, the GPS receiver analyzes them to obtain the signal transmission time. Simultaneously, the GPS receiver obtains the signal reception time using its own clock. Subtracting the two times and multiplying by the speed of light yields the distance between the GPS receiver and the satellite. Furthermore, the GPS receiver can obtain the satellite's motion parameters by analyzing the GPS signal, thus obtaining the satellite's coordinates. Precise positioning can then be achieved through calculation.
[0040] Please see Figure 2 , Figure 2 This diagram illustrates the principle of GPS positioning. In a geocentric coordinate system, the GPS receiver coordinates are (x, y, z), and the coordinates of satellite Si obtained by the GPS receiver are (x, y, z). Si ,y Si ,z Si ), i=1, 2, 3…, the pseudoranges measured by the GPS receiver are ρi, i=1, 2, 3, where the pseudoranges can be calculated using the following formula (1): (1) by Figure 2 Taking the reception of signals from three satellites as an example, formula (1) can be: (2) Based on formula (2), the specific values of x, y, and z can be solved, thereby obtaining the coordinates of the GPS receiver and realizing GPS positioning.
[0041] It should be noted that in practical scenarios, since the GPS receiver clock and the satellite clock cannot be perfectly synchronized, this embodiment introduces a new unknown quantity in formula (1): receiver clock difference t. u Therefore, formula (1) is modified to: (3) Where c represents the speed of light in a vacuum, and in this embodiment, c equals 3 × 10⁻⁶. 8 m / s.
[0042] Based on formula (3), the current coordinates (x, y, z) of the GPS receiver and the receiver clock error t can be obtained using the least squares method. u This enables GPS positioning.
[0043] It should be noted that GPS positioning is achieved by solving multiple pseudorange positioning equations. In transponder spoofing, the spoofing device delays and amplifies the received real signal, thereby changing the pseudorange value entering the GPS receiver loop and affecting the positioning result.
[0044] Please see Figure 3 , Figure 3 This diagram illustrates a satellite positioning and relay-based navigation deception method, assuming that the relay delay corresponding to satellite Si is... The corresponding GPS receiver (i.e. Figure 3 The pseudorange values of each satellite calculated by the target receiver B) upon receiving the induced signal are: (4) At this point, if the target receiver B needs to be located at the deceiving target point C, only adjustment is needed. , making This allows one to achieve the purpose of deception.
[0045] Furthermore, the induced path generation unit is equipped with a GPS positioning algorithm, which can achieve precise deception by dynamically generating a virtual trajectory that smoothly extends from the current location of the drone to a safe area.
[0046] Specifically, the induced path generation unit continuously generates a sequence of path points at a high refresh rate (e.g., once per second). For each new path point, the induced path generation unit calculates the forwarding delay required for all satellite signals in real time, and the second signal generator synchronously adjusts the deception signals of each channel, causing the pseudorange value received by the UAV to change dynamically.
[0047] Here, each channel refers to the signal transmission link of different GPS satellites. When the system generates the induced path, it calculates the required forwarding delay for each visible satellite at each path point. The second signal generator then synchronously adjusts the transmission timing and phase of the corresponding satellite signals on each channel. Dynamic change refers to the synchronous and continuous minute adjustment of the pseudorange values of all channels according to a preset trajectory, so that the position coordinates calculated by the UAV receiver produce the illusion of smooth position drift, rather than a sudden position jump.
[0048] It is understood that the dynamic guidance path obtained in this embodiment can match the phenomenon of the UAV moving at a constant speed along the preset path as simulated by UAV navigation, effectively simulating the continuous motion trajectory in real flight, thereby effectively avoiding the triggering of the protection mechanism of the UAV flight control system (such as triggering the UAV to hover) due to sudden changes in positioning information, and ensuring that the guidance process is stable and covert.
[0049] Those skilled in the art should understand that the division of the various modules in the embodiments is merely a division of logical functions. In actual applications, they can be fully or partially integrated into one or more actual carriers. These modules can be implemented entirely in software through processing unit calls, entirely in hardware, or a combination of software and hardware.
[0050] The intelligent countermeasure system for unmanned aerial vehicles (UAVs) proposed in this application firstly uses a detection and identification module 110 to monitor the target area in real time, which can quickly and accurately determine whether there is an UAV intrusion, providing basic information for subsequent countermeasures. Secondly, the positioning and direction finding module 120 determines the real-time position of the UAV, and the signal jamming module 130 interferes with the communication link between the UAV and the controller and the positioning signal based on the real-time position information, cutting off the normal communication between the UAV and the outside world, causing it to lose control commands and positioning capabilities. Finally, the path guidance module 140 generates an induction signal with the same structure as the original positioning signal of the UAV, guiding it to leave the target area along a dynamic induction path, effectively solving the problems of low fault tolerance and poor adaptability in the induction process in the prior art.

Based on the real-time location, transmit an induction signal to the UAV and generate a dynamic induction path, wherein the dynamic induction path is used to guide the UAV away from the target area when the UAV receives the induction signal.
[0052] It should be noted that each step in the intelligent countermeasure method for unmanned aerial vehicles in this embodiment corresponds one-to-one with each module in the intelligent countermeasure system for unmanned aerial vehicles in the aforementioned embodiment. Therefore, the specific implementation of this embodiment can refer to the implementation of the intelligent countermeasure system for unmanned aerial vehicles in the aforementioned embodiment, and will not be repeated here.

[0054] In another embodiment, the intelligent drone countermeasure method can also be applied to a vehicle-mounted drone defense system. This system is highly integrated into the vehicle platform and features real-time calibration capabilities, allowing for dynamic calibration of the vehicle's heading while in motion to ensure accurate positioning and jamming targeting. The system supports detection and handling of surrounding drones at speeds up to 140 km / h, making it suitable for mobile security scenarios.

[0056] Furthermore, the logical instructions in the aforementioned memory 330 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, essentially, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product.
