Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle interference, and in particular to a method for interfering with unmanned aerial vehicles and a device thereof, a countermeasure gun and a storage medium. Background Art

[0002] Unmanned aerial vehicles (UAVs) are increasingly used in civil and military fields, and the stability and security of their wireless communication links are particularly critical. Interference on this communication link can prevent the UAV from receiving control instructions or sending data, causing it to lose control or perform incorrect operations. UAV communication mainly includes two parts: flight control signals and image transmission signals. The flight control signal is responsible for the transmission of control information between the UAV and the remote control, while the image transmission signal is used to transmit the video data of the UAV. In order to enhance the robustness of the flight control signal in an interference environment, frequency hopping communication technology is currently widely used, combined with OFDM (Orthogonal Frequency-Division Multiplexing) modulation to improve the signal's anti-interference ability and spectrum utilization efficiency.

[0003] However, traditional spectrum interference methods mostly rely on broadband or narrowband noise interference, which has obvious shortcomings, such as low power efficiency, limited anti-interference ability for frequency hopping communications, and insufficient utilization of spectrum resources. Summary of the invention

[0004] One purpose of an embodiment of the present invention is to provide a method and device for jamming a drone, a countermeasure gun, and a storage medium, so as to solve the technical problem of poor jamming effect when jamming a drone.

[0005] In a first aspect, an embodiment of the present invention provides a method for jamming a drone, the method comprising:

[0006] Obtaining interference parameters corresponding to the target UAV, wherein the interference parameters are determined according to the UAV communication signal;

[0007] Generating a first OFDM interference signal according to the interference parameter;

[0008] Generate a target frequency sweep signal according to the first OFDM interference signal and the preset noise signal, wherein the target frequency sweep signal covers all operating frequency points of the UAV communication signal;

[0009] Signal interference is performed on the target UAV based on the target frequency sweep signal.

[0010] In combination with the first aspect, in a possible implementation method, generating a target frequency sweep signal according to the first OFDM interference signal and a preset noise signal includes: determining the preset noise signal according to a preset condition, wherein the preset condition is that the preset noise signal is consistent with the bandwidth in the first OFDM interference signal, and the preset noise signal and the first OFDM interference signal satisfy a preset power ratio; performing signal processing on the first OFDM interference signal and the preset noise signal to obtain a second OFDM interference signal; performing signal processing on the second OFDM interference signal to generate a target frequency sweep signal, wherein the target frequency sweep signal covers all operating frequency points of the UAV communication signal.

[0011] It can be seen that in this embodiment, by adding a preset noise signal, the interference effect is enhanced, the anti-avoidance capability of the interference signal is improved, and the target frequency sweep signal is further generated to have the required interference characteristics and can effectively interfere with the UAV communication system.

[0012] In combination with the first aspect, in a possible implementation, the signal processing of the second OFDM interference signal to generate a target swept frequency signal includes: obtaining a preset linear frequency modulation signal; mixing the second OFDM interference signal with the preset linear frequency modulation signal to generate a target swept frequency signal.

[0013] It can be seen that in this embodiment, the introduction of a preset linear frequency modulation signal can enhance the frequency change characteristics of the interference signal and improve the anti-avoidance capability of the interference signal; and through the mixing processing, the generated target frequency sweep signal not only retains the interference capability of the original interference signal, but also obtains the frequency sweep characteristic of the linear frequency modulation signal, thereby enabling the target frequency sweep signal to move within a wide frequency range, thereby effectively interfering with multiple communication frequency bands of the drone.

[0014] In combination with the first aspect, in a possible implementation method, the signal interference on the target UAV based on the target sweep frequency signal includes: obtaining the communication frequency band of the target UAV; performing frequency conversion processing on the target spectrum of the target sweep frequency signal to obtain a frequency-converted target sweep frequency signal consistent with the communication frequency band of the target UAV; performing data processing on the frequency-converted target sweep frequency signal to obtain a target transmission signal, wherein the target transmission signal is a target sweep frequency signal that meets the transmission requirements; and transmitting the target transmission signal to interfere with the signal of the target UAV.

[0015] It can be seen that this embodiment can obtain a target transmission signal with sufficient power and frequency range by performing transmission processing on the target frequency sweep signal before transmission to cover the spectrum range of the drone communication signal, thereby achieving effective interference.

[0016] In combination with the first aspect, in a possible implementation method, the data processing of the target frequency sweeping signal after the frequency conversion to obtain the target transmission signal includes: power amplifying the target frequency sweeping signal after the frequency conversion to obtain the power-amplified target frequency sweeping signal, and the power-amplified target frequency sweeping signal is the target transmission signal.

[0017] It can be seen that the target frequency sweep signal after power amplification processing in this embodiment has sufficient power to cover the communication range of the target UAV and achieve the expected interference effect.

[0018] In combination with the first aspect, in a possible implementation, generating a first OFDM interference signal according to the interference parameter includes: obtaining random data, the random data being used to simulate the data load of the target UAV in communication; converting the random data into modulation symbols according to a preset modulation mode; mapping the modulation symbols to the symbols in the interference parameters to obtain target symbols, the total number corresponding to the target symbols being the number of target symbols; allocating the target symbols to the subcarriers in the interference parameters according to the subcarrier spacing in the interference parameters to obtain target subcarriers that meet the subcarrier spacing, the target subcarriers indicating that each subcarrier carries a target symbol; performing time domain conversion on the target symbols on the target subcarriers to obtain converted target subcarriers, the converted target subcarriers indicating that each subcarrier carries the target symbol after time domain conversion; adding a cyclic prefix before each of the converted target subcarriers to obtain a first OFDM interference signal including the cyclic prefix length, the cyclic prefix being determined by the cyclic prefix length in the interference parameters.

[0019] It can be seen that in this embodiment, an OFDM interference signal including a cyclic prefix is ​​generated according to the interference parameters. The OFDM signal simulates the OFDM signal used in normal UAV communications, but because it is generated based on random data, it does not carry useful information. It is intended to block or interfere with the control channel and image transmission channel of the target UAV by interfering with the normal signal of the target UAV communication, thereby affecting the normal operation of the UAV.

[0020] In combination with the first aspect, in a possible implementation method, obtaining interference parameters corresponding to the target UAV includes: obtaining model parameters of the target UAV; determining characteristics of a flight control signal and an image transmission signal of the target UAV based on the model parameters; and determining the interference parameters of the target UAV based on the characteristics of the flight control signal and the image transmission signal.

[0021] It can be seen that the interference parameters determined in this embodiment can exert an influence on the communication system of a specific drone, thereby achieving effective control or interference of the drone, further ensuring that the entire process complies with relevant laws and regulations, and ensuring that no interference or damage is caused to other legitimate airspace users when performing interference operations.

[0022] In a second aspect, an embodiment of the present invention provides a jamming device for a drone, the device comprising:

[0023] An acquisition unit, configured to acquire interference parameters corresponding to a target UAV, wherein the interference parameters are determined according to a UAV communication signal;

[0024] A generating unit, configured to generate a first OFDM interference signal according to the interference parameter;

[0025] The generating unit is further configured to generate a target frequency sweep signal according to the first OFDM interference signal and a preset noise signal, wherein the target frequency sweep signal covers all operating frequency points of the UAV communication signal;

[0026] An interference unit is used to perform signal interference on the target UAV based on the target sweep frequency signal.

[0027] In a third aspect, a countermeasure gun is provided, comprising a memory and a processor, wherein the memory is connected to the processor, and the processor is used to execute one or more computer programs stored in the memory, and when the processor executes the one or more computer programs, the countermeasure gun implements the interference method of the drone as described in the first aspect.

[0028] In a fourth aspect, a computer-readable storage medium is provided, wherein the computer-readable storage medium stores a computer program, wherein the computer program includes program instructions, and when the program instructions are executed by a processor, the processor executes the interference method of the drone as described in the first aspect.

[0029] In the embodiments implemented by the above-mentioned interference method and device of the UAV, the countermeasure gun and the storage medium, the interference parameters corresponding to the target UAV are first obtained, and the interference parameters are determined according to the UAV communication signal. Secondly, according to the interference parameters, a first OFDM interference signal is generated. Then, according to the first OFDM interference signal and the preset noise signal, a target sweep signal is generated, and the target sweep signal covers all the operating frequencies of the UAV communication signal. Finally, based on the target sweep signal, the signal of the target UAV is interfered. This embodiment obtains the OFDM interference signal parameters of the target UAV and generates an OFDM interference signal that matches it, ensuring that the generated interference signal matches the communication signal characteristics of the target UAV, thereby achieving precise interference and enhancing the interference effect. The OFDM interference signal parameters can be adjusted according to real-time needs, and can adapt to the communication parameters and anti-interference capabilities of different UAVs, thereby improving the flexibility of interference and optimizing the interference effect. The OFDM interference signal is further combined with the noise signal to generate a more interference-capable swept frequency signal, which can perform spectrum scanning within the communication frequency band of the target UAV, ensuring comprehensive interference to its communication link, improving the effective coverage of the interference signal, and thereby improving the interference effect on the target UAV. Finally, by accurately generating and transmitting interference signals, the occupation of other spectrum resources is reduced, unnecessary interference is avoided, and the efficiency of interference is improved.

[0034] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] It should be noted that, if there is no conflict, the various features in the embodiments of the present invention can be combined with each other, all within the scope of protection of the present invention. In addition, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a different order from the module division in the device or the flow chart. Furthermore, the words "first", "second", "third", etc. used in the present invention do not limit the data and execution order, but only distinguish the same items or similar items with basically the same functions and effects.

[0036] In addition to the problems with the related technologies pointed out in the background technology, other related problems are also found: (1) When facing drones of different models and communication protocols, traditional jamming methods may lack sufficient adaptability and cannot effectively interfere with specific drones; (2) Traditional jamming equipment may require professional operators to configure and operate, which increases the complexity of use.

[0037] In order to solve these problems, the present method proposes a method for jamming a UAV. In the present embodiment, the OFDM jamming signal parameters of the target UAV are obtained to generate an OFDM jamming signal matching the target UAV, thereby ensuring that the generated jamming signal matches the communication signal characteristics of the target UAV, thereby achieving precise jamming and enhancing the jamming effect. The OFDM jamming signal parameters can be adjusted according to real-time needs, and can adapt to the communication parameters and anti-interference capabilities of different UAVs, thereby improving the flexibility of jamming and optimizing the jamming effect. The OFDM jamming signal is further combined with the noise signal to generate a frequency sweeping signal with greater jamming capability. The frequency sweeping signal can perform spectrum scanning within the communication frequency band of the target UAV, ensuring comprehensive jamming of its communication link, improving the effective coverage of the jamming signal, and thereby improving the jamming effect on the target UAV. Finally, by accurately generating and transmitting jamming signals, the occupation of other spectrum resources is reduced, unnecessary interference is avoided, and thus the efficiency of jamming is improved.

[0038] See also Figure 1 , Figure 1 A flowchart of a method for jamming a drone provided by an embodiment of the present invention is provided. The method comprises the following steps:

[0039] S10. Obtain interference parameters corresponding to the target UAV, where the interference parameters are determined according to the UAV communication signal.

[0040] The interference parameters include but are not limited to the number of symbols, the number of subcarriers, the subcarrier spacing, and the cyclic prefix length.

[0041] Specifically, the number of symbols refers to the total number of symbols contained in the OFDM signal. In OFDM technology, one symbol can carry signals of multiple subcarriers. The number of symbols directly affects the time domain length and frequency domain distribution of the interference signal. The more symbols there are, the longer the time length of the interference signal, which may affect the interference effect on the drone communication link. Adjusting the number of symbols can help simulate interference signals of different durations to evaluate different interference scenarios for the target drone communication.

[0042] Specifically, the number of subcarriers refers to the total number of subcarriers allocated in the OFDM signal. Each subcarrier can carry data independently. The number of subcarriers determines the frequency domain resolution of the OFDM signal. Increasing the number of subcarriers can improve the efficiency and resolution of spectrum utilization. Selecting the appropriate number of subcarriers helps to generate interference signals with different frequency domain characteristics, which in turn affects the communication link of the target drone.

[0043] Specifically, the subcarrier spacing is the frequency difference between adjacent subcarriers. It determines the bandwidth and spectrum distribution of each subcarrier. The subcarrier spacing affects the frequency domain bandwidth of the OFDM signal and the frequency domain characteristics of the interference. Smaller subcarrier spacing can make the signal denser, thereby covering more frequency ranges on the spectrum, which may cause more extensive interference to the target drone's signal.

[0044] Specifically, the cyclic prefix is ​​a redundant part added before each OFDM symbol to offset the multipath effect and improve the stability of the signal. The cyclic prefix length refers to the length of this redundant part. The cyclic prefix length affects the robustness of the OFDM signal to the multipath effect. A longer cyclic prefix can effectively alleviate multipath interference, but it will also increase the system overhead. According to the environment of the target drone communication link, choosing an appropriate cyclic prefix length can help generate an effective interference signal.

[0045] In the process of obtaining the interference parameters corresponding to the target UAV, the initial interference parameters can be set by analyzing the signals of different UAVs, and the initial interference parameters are the interference parameters of the obtained target UAV. The initial interference parameters can be determined by the technical specifications, standard documents or previous experimental data of the UAV communication system, or calculated based on the analysis of different UAV signals, and are not limited here.

[0046] It can be seen that in this embodiment, by obtaining and setting the OFDM interference parameters for the target UAV communication link, it is ensured that the parameters in the subsequently generated interference signal are the same as the parameters of the OFDM signal used for the UAV signal, thereby ensuring the consistency of the interference signal and the UAV communication signal in the spectrum, thereby improving the interference effect.

[0047] S20. Generate a first OFDM interference signal according to the interference parameter.

[0048] The first OFDM interference signal includes but is not limited to modulation symbols, number of subcarriers, cyclic prefix length, and time domain signals.

[0049] In which, in the first OFDM interference signal, the number and type of modulation symbols carried by each subcarrier correspond to the number of symbols and the number of subcarriers in the interference parameters; and the spectrum distribution and time domain characteristics (such as inter-symbol interference and power distribution) of the first OFDM interference signal are affected by the subcarrier spacing and the cyclic prefix length.

[0050] It can be seen that the first OFDM interference signal generated in this example will have similar characteristics to the target UAV communication signal, thereby being able to more effectively interfere with the normal communication of the UAV.

[0051] S30. Generate a target frequency sweep signal according to the first OFDM interference signal and the preset noise signal, wherein the target frequency sweep signal covers all operating frequency points of the UAV communication signal.

[0052] Among them, the target sweep frequency signal refers to the sweep frequency signal that can effectively interfere with the communication of the UAV after processing.

[0053] Among them, in the process based on the first OFDM interference signal and the preset noise signal, a target frequency sweep signal can be generated according to signal processing, and the signal processing can include but is not limited to filtering, modulation, mixing and other steps to enhance the power and complexity of the interference signal.

[0054] Among them, the preset noise signal refers to the noise signal used to enhance the interference effect during the interference process. The preset noise signal includes but is not limited to Gaussian white noise. Gaussian white noise has the characteristic of uniform energy distribution in the entire bandwidth, which is similar to the noise characteristics of the actual communication signal, and can effectively increase the concealment and interference effect of the interference signal. It can be seen that the generation of the target frequency sweep signal in this embodiment is adjusted and optimized according to the first OFDM interference signal and the demand obtained by the interference parameters of the drone. Further, the target frequency sweep signal has the characteristic of gradually changing frequency and covers the specified frequency band to ensure that the interference effect reaches the expected effect.

[0055] S40: performing signal interference on the target UAV based on the target frequency sweeping signal.

[0056] Signal jamming refers to interfering with the normal communication of the target drone by transmitting a specific signal. That is, the jamming signal is mixed with the communication signal of the target drone, thereby reducing the quality of the received signal and making it impossible for the drone to receive commands or send information from its control source.

[0057] Among them, the target scanning signal is sent to the area where the target UAV is located through the transmitting equipment, and its frequency and power are designed to cover and interfere with the communication frequency band of the target UAV.

[0058] Optionally, while jamming the signal, the response of the drone and changes in the communication status are monitored, and the parameters of the jamming signal (such as frequency, power, etc.) can be adjusted in real time as needed to optimize the jamming effect.

[0059] It can be seen that in this embodiment, signal interference is effectively implemented on the target UAV based on the target frequency scanning signal, reducing or eliminating its ability to operate through the communication channel.

[0060] This embodiment obtains the OFDM interference signal parameters of the target UAV and generates an OFDM interference signal that matches it, ensuring that the generated interference signal matches the communication signal characteristics of the target UAV, thereby achieving precise interference and enhancing the interference effect. The OFDM interference signal parameters can be adjusted according to real-time needs, and can adapt to the communication parameters and anti-interference capabilities of different UAVs, thereby improving the flexibility of interference and optimizing the interference effect. The OFDM interference signal is further combined with the noise signal to generate a more interference-capable swept frequency signal, which can perform spectrum scanning within the communication frequency band of the target UAV, ensuring comprehensive interference to its communication link, improving the effective coverage of the interference signal, and thereby improving the interference effect on the target UAV. Finally, by accurately generating and transmitting interference signals, the occupation of other spectrum resources is reduced, unnecessary interference is avoided, and the efficiency of interference is improved.

[0061] In one embodiment, generating a target frequency sweep signal according to the first OFDM interference signal and a preset noise signal includes: determining the preset noise signal according to a preset condition, wherein the preset condition is that the preset noise signal is consistent with the bandwidth in the first OFDM interference signal, and the preset noise signal and the first OFDM interference signal satisfy a preset power ratio; performing signal processing on the first OFDM interference signal and the preset noise signal to obtain a second OFDM interference signal; performing signal processing on the second OFDM interference signal to generate a target frequency sweep signal, wherein the target frequency sweep signal covers all operating frequency points of the UAV communication signal.

[0062] The preset condition is that the bandwidth of the preset noise signal is consistent with that of the first OFDM interference signal, and the preset noise signal and the first OFDM interference signal meet the preset power ratio. Specifically, the preset power ratio is to control the noise power to prevent the power from being too large to drown the previous OFDM signal, and the preset power can be set manually, which is not the only limitation here.

[0063] The above-mentioned signal processing may include but is not limited to signal superposition, filtering, mixing, modulation and demodulation, frequency conversion, etc. Specifically, the signal processing in the signal processing of the first OFDM interference signal and the preset noise signal may be superposition processing; the signal processing in the signal processing of the second OFDM interference signal may be mixing processing.

[0064] In the specific implementation of signal processing of the first OFDM interference signal and the preset noise signal, the generated preset noise signal is added to the first OFDM interference signal to obtain a second OFDM interference signal. The mixing process can be achieved by simple addition, that is, adding the noise signal to each time domain sample.

[0065] Specifically, during the summing process, the bandwidth of the second OFDM interference signal remains consistent with that of the first OFDM interference signal, because during the summing process, the noise signal is only superimposed in the time domain without changing the spectrum characteristics of the original signal. In terms of frequency, the center frequency of the second OFDM interference signal is also the same as that of the first OFDM signal. The introduction of the noise signal mainly enhances the interference effect through changes in power and phase without changing its basic frequency characteristics.

[0066] Among them, the target sweep signal refers to a sweep signal that can effectively interfere with drone communications after signal processing. The frequency of the target sweep signal changes over time and can be scanned over a wide frequency range, thereby improving the coverage and countermeasure capability of the interference. Generating the target sweep signal involves modulating the second OFDM interference signal so that it appears as a sweep pattern on the spectrum.

[0067] For example, the preset conditions are: the bandwidth of the first OFDM interference signal is 10 MHz, the preset power ratio is 3 dB (the power of the preset noise signal is 3 dB higher than that of the first OFDM interference signal), the modulation is QPSK; and the number of symbols is 128. First, a Gaussian white noise signal with a bandwidth of 10MHz (the preset noise signal in this embodiment) is generated. The bandwidth is consistent with the bandwidth of the first OFDM interference signal. Assuming that the power of the first OFDM interference signal is 1W, the power of the preset noise signal is 2W (because the noise power is 3dB higher than that of the first OFDM signal, which is equivalent to a 2-fold increase in power), so the preset noise signal is obtained: a Gaussian white noise with a bandwidth of 10MHz and a power of 2W is generated; secondly, the first OFDM interference signal is s1, the preset noise signal is n1, and the second OFDM interference signal = s1 + n1; finally, a linear frequency modulation signal is designed, and the frequency range of the frequency modulation signal is from 1GHz to 1.1GHz; the second OFDM interference signal is mixed with the linear frequency modulation signal to obtain a target swept frequency signal, which appears as a signal with linear frequency variation in the spectrum, covering the frequency range of 1GHz to 1.1GHz.

[0068] Among them, the advantage of OFDM interference being superimposed with preset noise and processed into frequency sweep interference is that this method can effectively cope with the rapid frequency hopping characteristics of drones. Since drones frequently change communication frequencies during communication, when using OFDM interference signals alone, the process of generating interference signals takes a certain amount of time, and during this period of time, the flight control signal of the drone is likely to have jumped to the next frequency, resulting in poor interference effect. By superimposing OFDM interference with preset noise and processing it into frequency sweep interference, continuous interference to drone communications can be achieved without synchronizing the frequency hopping of interference and flight control signals. This method can cover a wider frequency band, thereby improving the success rate of interference, ensuring that the drone cannot normally receive the flight control signal after being interfered, and achieving the purpose of effective countermeasures. It can be seen that in this embodiment, by adding a preset noise signal, the interference effect is enhanced, the anti-avoidance capability of the interference signal is improved, and the target frequency sweep signal is further generated to have the required interference characteristics, and can effectively interfere with the drone communication system.

[0069] In one embodiment, the signal processing of the second OFDM interference signal to generate a target swept frequency signal includes: acquiring a preset linear frequency modulation signal; mixing the second OFDM interference signal with the preset linear frequency modulation signal to generate a target swept frequency signal.

[0070] The preset linear frequency modulation signal may be as follows:

[0071]

[0072] Where A is the amplitude, B is the bandwidth, T is the time length, f0 is the initial frequency, is the initial phase, and s2(t) is the preset linear frequency modulation signal.

[0073] The preset linear frequency modulation signal refers to a signal whose frequency changes linearly with time. At the beginning, the signal may have the lowest frequency value, and then the frequency will increase uniformly until it reaches the highest frequency value.

[0074] The purpose of the mixing process is to combine two or more signals of different frequencies to generate a new signal. Therefore, the mixing process is to perform point-by-point multiplication of the second OFDM interference signal and the preset linear frequency modulation signal, and the spectrum distribution of the second OFDM interference signal changes to generate a signal with a swept frequency characteristic.

[0075] If the OFDM signal is s1, the preset noise signal is n1, and the linear frequency modulation signal is s2, the target frequency sweep signal S after mixing is:

[0076] S=(s1+n1)*s2

[0077] It can be seen that in this implementation, the introduction of a preset linear frequency modulation signal can enhance the frequency change characteristics of the interference signal and improve the anti-avoidance capability of the interference signal; and through the mixing processing, the generated target frequency sweep signal not only retains the interference capability of the original interference signal, but also obtains the frequency sweep characteristic of the linear frequency modulation signal, thereby enabling the target frequency sweep signal to move within a wide frequency range, effectively interfering with multiple communication frequency bands of the drone.

[0078] In one embodiment, the signal interference on the target UAV based on the target sweep frequency signal includes: obtaining the communication frequency band of the target UAV; performing frequency conversion processing on the target spectrum of the target sweep frequency signal to obtain a frequency-converted target sweep frequency signal consistent with the communication frequency band of the target UAV; performing data processing on the frequency-converted target sweep frequency signal to obtain a target transmission signal, wherein the target transmission signal is a target sweep frequency signal that meets the transmission requirements; and transmitting the target transmission signal to interfere with the signal of the target UAV.

[0079] The communication frequency band of the above-mentioned drone refers to the frequency range used by the drone for communication, which may include the frequencies used by flight control signals and image transmission signals. For example, drones use the frequency band of 2.4 GHz to 2.5 GHz for control and data transmission.

[0080] In the specific implementation of obtaining the communication frequency band of the target UAV, the method of obtaining the communication frequency band may include but is not limited to public technical manuals, radio spectrum analysis, or attempting to identify by monitoring UAV communications.

[0081] Among them, frequency conversion processing refers to adjusting the frequency range of the target sweep signal to be consistent with the communication frequency band of the target UAV. Frequency conversion processing uses technical means to adjust or modify the frequency of the signal to match the communication frequency band of the target UAV. Frequency conversion can be achieved through mixing methods. Mixing synthesizes signals of two or more frequencies to generate new frequency signals.

[0082] Therefore, the above-mentioned target frequency sweeping signal after frequency conversion is a frequency sweeping signal after frequency conversion processing, and its spectrum has been adjusted to the communication frequency band of the target UAV.

[0083] Data processing refers to further adjusting and optimizing the target frequency sweep signal after frequency conversion to meet the transmission requirements. Data processing may include but is not limited to filtering, modulation, power adjustment, etc. to ensure the transmission effect of the target frequency sweep signal.

[0084] Among them, the transmission requirements include but are not limited to the transmission power range, frequency range, bandwidth requirements, modulation format, transmission equipment specifications, etc. For example, the transmission requirements are set as follows: the frequency range of the target transmission signal is 2.4GHz to 2.5GHz, and the bandwidth is 100MHz; the transmission power is set to 20dBm, which must comply with local regulations; the modulation format is QPSK modulation; the equipment specification is that the transmitter complies with FCC standards.

[0085] The target transmission signal is a signal after data processing, which can meet the target frequency sweep signal required for transmission. The target transmission signal not only needs to have sufficient power, but also needs to comply with the emission standards and radio frequency management regulations to ensure its legality and safety.

[0086] Among them, transmission refers to sending the target transmission signal into the air through a transmitting device (such as an antenna). The transmitting device needs to be adjusted according to the communication range and direction of the target UAV to ensure that the signal can cover the target UAV.

[0087] For example, assuming that the communication frequency band of the target UAV is 2.4GHz to 2.5GHz, and the spectrum range of the target sweep signal is 1GHz to 2GHz, the frequency of the target sweep signal is added with a fixed frequency shift (for example, 1.4GHz) to move it to the frequency band of 2.4GHz to 2.5GHz, and the target sweep signal after frequency conversion is obtained, and its spectrum range has been adjusted to 2.4GHz to 2.5GHz; the signal after frequency conversion is adjusted to 20dBm power and QPSK modulation format to obtain the target transmit signal, and the target transmit signal is transmitted to interfere with the UAV.

[0088] It can be seen that in this embodiment, by performing transmission processing on the target frequency sweep signal before transmission, a target transmission signal with sufficient power and frequency range can be obtained to cover the spectrum range of the drone communication signal, thereby achieving effective interference.

[0089] In one embodiment, the data processing of the target frequency sweeping signal after frequency conversion to obtain the target transmission signal includes: power amplifying the target frequency sweeping signal after frequency conversion to obtain the power-amplified target frequency sweeping signal, wherein the power-amplified target frequency sweeping signal is the target transmission signal.

[0090] Among them, power amplification processing refers to increasing the power of the signal to a level sufficient to propagate in the air and achieve the expected interference effect.

[0091] Among them, the target frequency sweep signal after power amplification is a signal enhanced by a power amplifier, its power has reached or exceeded the transmission requirements, and its output power is higher than the original signal level after frequency conversion. The target frequency sweep signal after power amplification has large energy, which is sufficient to effectively interfere with the communication frequency band of the target UAV.

[0092] It can be seen that the target frequency sweep signal after power amplification processing in this embodiment has sufficient power to cover the communication range of the target UAV and achieve the expected interference effect.

[0093] In one embodiment, generating a first OFDM interference signal according to the interference parameter includes: obtaining random data, the random data being used to simulate the data load of the target UAV in communication; converting the random data into modulation symbols according to a preset modulation mode; mapping the modulation symbols to the symbols in the interference parameters to obtain target symbols, the total number corresponding to the target symbols being the number of target symbols; allocating the target symbols to the subcarriers in the interference parameters according to the subcarrier spacing in the interference parameters to obtain target subcarriers that meet the subcarrier spacing, the target subcarriers indicating that each subcarrier carries a target symbol; performing time domain conversion on the target symbols on the target subcarriers to obtain converted target subcarriers, the converted target subcarriers indicating that each subcarrier carries the target symbol after time domain conversion; adding a cyclic prefix before each of the converted target subcarriers to obtain a first OFDM interference signal including the cyclic prefix length, the cyclic prefix being determined by the cyclic prefix length in the interference parameters.

[0094] The modulation mode refers to a method of converting a digital signal into an analog signal. The preset modulation mode may include but is not limited to BPSK (bi-phase keying), QPSK (quadrature phase shift keying), 16-QAM (16-order quadrature amplitude modulation), etc.

[0095] Random data refers to a bit stream or byte stream generated by a random number generator. It is used to simulate the data load in communication, that is, the data content transmitted in the actual signal. In jamming signal generation, random data helps create simulated data loads to simulate the data situation of the target drone in actual communication.

[0096] The modulation symbol refers to the signal unit after modulation, which represents specific data. During the modulation process, the data bit is mapped to a specific signal state (such as phase, amplitude, etc.), which is the modulation symbol.

[0097] In the specific process of converting the random data into modulation symbols according to the preset modulation mode, the random data is divided into several groups, and the number of bits of each group of data depends on the modulation mode. For example, each symbol of QPSK represents 2 bits, and each symbol of 16-QAM represents 4 bits; each group of data is converted into a modulation symbol through a modulation method, for example, every 2 bits of data in QPSK corresponds to a QPSK symbol, and the corresponding symbol is generated through a modulation matrix or a mapping rule.

[0098] The target symbol is obtained by mapping the modulation symbol according to the requirements in the interference parameter. The number of target symbols refers to the total number of generated target symbols, which will be used to construct the interference signal.

[0099] The subcarrier spacing refers to the frequency spacing between adjacent subcarriers in the OFDM signal. Specifically, during the target symbol allocation process, each target symbol is mapped to a different subcarrier to ensure that each subcarrier is consistent with its corresponding symbol spacing. Each subcarrier will carry one target symbol.

[0100] Among them, time domain conversion is the process of converting frequency domain signals into time domain signals in OFDM signals. Usually, IFFT (Inverse Fast Fourier Transform) is used to convert the frequency domain signal of each subcarrier into a waveform signal in the time domain. In this embodiment, the target symbol on the target subcarrier is converted into a signal carrying time domain sampling points. These signals together constitute a complete OFDM signal, which is ready to be sent to the wireless channel.

[0101] Among them, a cyclic prefix is ​​added before each of the converted target subcarriers in order to reduce or eliminate inter-symbol interference. The cyclic prefix is ​​a section at the end of the OFDM signal copied to the beginning of the signal, ensuring that during the reception of a symbol, the signal delay caused by multipath still falls within the time of the cyclic prefix and does not affect the main OFDM signal. The time domain OFDM signal with the cyclic prefix added becomes an interference signal that can be sent on the wireless channel.

[0102] For example, assume that the interference parameters are as follows: the modulation mode is QPSK; the target number of symbols is 128; the subcarrier spacing is 15kHz; the cyclic prefix length is 64 samples; generate random data of length 256 bits; divide the 256 bits of random data into 128 groups, each with 2 bits; use QPSK modulation, map every 2 bits to a symbol, and get 128 QPSK symbols, that is, each modulation symbol will be mapped to a target symbol, so finally get 128 target symbols; based on the subcarrier spacing, define the frequency position of 128 subcarriers, each subcarrier The wave carries a target symbol; a spectrum is generated with a frequency range of 000 to 1.92MHz (128×15kHz); the frequency domain signal of 128 subcarriers is processed by IFFT to convert it into a time domain signal. The result of IFFT is a time domain signal containing 128 OFDM symbols; a cyclic prefix of 64 samples is added in front of each OFDM symbol, and finally an OFDM interference signal is generated, including 128 modulation symbols, each symbol is assigned to a subcarrier with a spacing of 15kHz, and a cyclic prefix of 64 samples is added. This interference signal can be effectively used to counter the communication system of the target drone.

[0103] It can be seen that in this embodiment, an OFDM interference signal including a cyclic prefix is ​​generated according to the interference parameters. The OFDM signal simulates the OFDM signal used in normal UAV communications, but because it is generated based on random data, it does not carry useful information. It is intended to block or interfere with the control channel and image transmission channel of the target UAV by interfering with the normal signal of the target UAV communication, thereby affecting the normal operation of the UAV.

[0104] In one embodiment, obtaining interference parameters corresponding to the target UAV includes: obtaining model parameters of the target UAV; determining characteristics of a flight control signal and an image transmission signal of the target UAV based on the model parameters; and determining interference parameters of the target UAV based on the characteristics of the flight control signal and the image transmission signal.

[0105] Among them, model parameters refer to the model information of the drone, including manufacturer, product series, version number, communication protocol used (such as Wi-Fi, Bluetooth, custom RF protocol, etc.), frequency range used for flight control and image transmission, bandwidth of communication channel, etc., which are not limited here.

[0106] Among them, the above-mentioned acquisition process can identify the model parameters of the drone by analyzing the physical characteristics, radio identification, network signal characteristics of the drone or by direct database query in specific cases.

[0107] Among them, in the process of determining the characteristics of the flight control signal and the image transmission signal of the target UAV according to the model parameters, the technical manual or product manual of the UAV is obtained through the model parameters of the UAV, and the characteristics of the flight control signal and the characteristics of the image transmission signal are obtained by searching the technical manual or product manual of the UAV.

[0108] Furthermore, other measurement tools can be used to measure the flight control signal and image transmission signal of the actual drone to confirm whether the information obtained from the technical documentation is accurate. If it is incorrect, the flight control signal and image transmission signal can be modified.

[0109] Among them, the characteristics of the flight control signal may include but are not limited to the operating frequency band such as (2.4GHz, 5.8GHz), modulation method (PWM (Pulse Width Modulation, pulse width modulation, PPM (Pulse Position Modulation) or other modulation methods), data transmission rate and signal structure, etc.

[0110] Among them, the characteristics of the image transmission signal may include but are not limited to the operating frequency band (such as 5.8GHz), modulation method (such as OFDM (orthogonal frequency division multiplexing), QPSK (quadrature phase shift keying) or 16-QAM (16-order quadrature amplitude modulation)), data transmission rate, frame structure and encoding method (such as H.264, H.265).

[0111] Among them, in the process of determining the interference parameters of the target UAV according to the characteristics of the flight control signal and the image transmission signal, the frequency band of the interference signal is selected according to the frequency bands of the flight control signal and the image transmission signal. For example, if the flight control signal is in the 2.4GHz range, the frequency band of the interference signal should be concentrated in this range; according to the bandwidth requirements of the image transmission signal and the modulation method of the flight control signal, the bandwidth and power level of the interference signal are determined; according to the modulation method and data rate of the flight control signal, the parameters of the OFDM interference signal (such as the number of subcarriers, subcarrier spacing, and cyclic prefix length) are set.

[0112] For example, assume that the flight control signal of the drone operates in the 2.4GHz frequency band, uses QPSK modulation, and has a data rate of 1Mbps, and the image transmission signal operates in the 5.8GHz frequency band, uses 16-QAM modulation, and has a bandwidth of 10MHz. The corresponding interference signal design steps are as follows: Design an OFDM interference signal in the flight control signal interference, with a subcarrier spacing of 15kHz, a number of subcarriers of 128, superimposed Gaussian white noise, and a power adjustment of 5dB; design a noise signal with a bandwidth of 10MHz in the image transmission signal interference, covering the 5.8GHz frequency band, to effectively interfere with the transmission of the image transmission signal.

[0113] It can be seen that the interference parameters determined in this embodiment can exert an influence on the communication system of a specific drone, thereby achieving effective control or interference of the drone, further ensuring that the entire process complies with relevant laws and regulations, and ensuring that no interference or damage is caused to other legitimate airspace users when performing interference operations.
