[0003] When drones are equipped with electronic warfare equipment, their electromagnetic compatibility (EMC) conditions become even more severe. The addition of EW equipment further increases the complexity of electromagnetic signals and sources of interference, further congesting already limited RF resources and making RF compatibility between various devices challenging.

Obviously, the drawings described below are merely embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying any creative work.

[0044] Figure 2 This is a schematic structural diagram of a radio frequency compatible device disclosed in the present invention;

[0045] Figure 3 This is a structural diagram of an electronic device disclosed in the present invention. DETAILED DESCRIPTION

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] When electronic warfare equipment is added to drones, their electromagnetic compatibility conditions become even worse. The addition of electronic warfare equipment further increases the complexity of electromagnetic signals and interference sources, making the already tight radio frequency resources even more crowded, and making radio frequency compatibility between various types of equipment difficult. When dealing with the special electromagnetic environment of drones, existing radio frequency compatibility technologies have difficulty in effectively coordinating frequency usage between numerous devices, resulting in reduced equipment performance and seriously affecting the efficiency and reliability of drone mission execution. To this end, the present invention provides a radio frequency compatibility method, apparatus, equipment, and storage medium that can improve the radio frequency compatibility of frequency-using equipment in electronic warfare drone systems.

[0048] See also Figure 1 As shown, an embodiment of the present invention discloses a radio frequency compatibility method, including:

[0049] Step S11: In the electronic warfare UAV system, simulation is performed based on the preset electromagnetic field simulation software, the antenna radiation model of each frequency-using device of the UAV, and the body shape, and the spatial isolation and signal strength obtained by simulation are used to determine the conflict source device among each of the frequency-using devices; wherein, the conflict source device is a device whose transmitting frequency band and receiving frequency band between each frequency-using device meet the preset frequency band similarity condition.

[0050] In this embodiment, it's important to first clarify that the electronic warfare drone system includes various frequency-using devices. Conventional reconnaissance and strike drones are equipped with radar, air traffic control transponders, and communications data links. These devices all achieve their functions by receiving and transmitting electromagnetic waves at specific frequencies. Therefore, these devices can be referred to as frequency-using devices, covering nearly the entire frequency band from VHF (Very High Frequency) to KU (K-underband).

[0051] Furthermore, the antenna radiation models for each frequency-using device and the drone's body shape must be input into pre-set electromagnetic field simulation software for electromagnetic simulation. The pre-set electromagnetic field simulation software accurately solves electromagnetic field problems, providing detailed electromagnetic field distribution diagrams and performance parameters. The antenna radiation model details the radiation characteristics of each frequency-using device's antenna, including parameters such as radiation pattern and gain. The body shape considers the impact of the drone's structure on electromagnetic wave propagation, such as reflection and scattering.

[0052] After entering this information into the software, electromagnetic simulation is initiated. During the simulation, the interaction of electromagnetic waves generated by each frequency-consuming device during operation and the degree of spatial isolation are simulated. Specifically, the software calculates information such as the intensity, direction, and frequency of the electromagnetic waves emitted by each device based on the antenna radiation model, taking into account the effects of the device's shape on reflection, refraction, and scattering of electromagnetic waves. Furthermore, the signal strength radiated from the electromagnetic wave transmitting device to the electromagnetic wave receiving device must be determined.

[0053] After obtaining the signal strength, the conflict source device is identified from each frequency-using device based on the signal strength and electromagnetic simulation results. Conflict source devices are identified based on the fact that the transmitting and receiving frequency bands of each frequency-using device meet a preset frequency band similarity condition and that the signal interference between the devices is significant enough to cause device performance degradation or failure. It should be noted that frequency band similarity in the preset frequency band similarity condition specifically refers to overlap between the transmitting and receiving frequency bands. In other words, to determine conflict source devices, if the transmitting frequency band of one device is similar to the receiving frequency band of another device, and the signal interference between them has severely impacted the normal performance of at least one device, causing performance degradation or even failure, then the two devices are considered conflict source devices. Specifically, when the transmitting frequency band of one device is similar to the receiving frequency band of another device, electromagnetic interference may be generated. The severity of this interference can be determined by calculating the signal strength radiated from the transmitting device to the receiving device. If the signal strength exceeds the interference immunity of the receiving device, the two devices are likely conflict source devices. The transmitting device is called the interference source, and the receiving device is called the sensitive source.

[0054] Step S12: Analyze the time domain characteristics and frequency domain characteristics of the conflict source device to obtain analysis results.

[0055] In this embodiment, after determining the conflict source devices for each frequency-using device in the electronic warfare drone system, it is necessary to analyze the time domain and frequency domain characteristics of the conflict source devices. As shown in Table 1, different conflict source devices have their own unique characteristics. For example, the frequency domain characteristics of radar signals are that the frequency point is not fixed, the instantaneous operating frequency band is variable, and it appears in the form of pulses in the time domain. Air traffic control transponders exhibit the characteristics of a fixed operating frequency band in the frequency domain and also in the form of pulses in the time domain. The instantaneous operating frequency band of the data link is variable, but the changes are infrequent, the bandwidth is narrow, and it is a continuous wave in the time domain. The frequency point of electronic warfare signals is not fixed in the frequency domain, the instantaneous operating bandwidth is variable, and it appears as a pulse signal in the time domain.

[0056] Table 1

[0057]

[0058] By analyzing the spatial isolation, time domain, and frequency domain characteristics of these conflict source devices in detail, comprehensive analysis results can be obtained. These results will provide important basic data for subsequent interface design and the formulation of RF management strategies.

[0059] Step S13: Determine the interface design of the conflict source device using the analysis result, and formulate a radio frequency management strategy based on the interface design and the current combat scenario, so as to perform corresponding radio frequency compatibility management on the conflict source device based on the radio frequency management strategy.

[0060] For the analysis result obtained in step S12, in a specific embodiment, when the analysis result shows that the time domain of the conflict source device is a pulse signal and the frequency change rate in the frequency domain is greater than the preset rate threshold, the first locking timing interface and the first compatible parameter interface are configured for the conflict source device.

[0061] Specifically, the first lock timing interface is used to transmit the first amplitude of the level signal, so as to indicate whether the conflict source device is radiating electromagnetic waves through the first amplitude. Through this interface, the system can understand the radiation status of the device in real time. When the device is in the radiation state, the level signal presents a specific amplitude value, otherwise it presents another amplitude value. In this way, other devices can judge whether to take corresponding measures to avoid interference based on this signal. In addition, the first compatible parameter interface is an interface for transmitting the instantaneous working RF bandwidth and RF frequency band of the conflict source device. Since the instantaneous working frequency band of this type of conflict source device changes rapidly, accurately obtaining its instantaneous working RF bandwidth and frequency band information through this interface is crucial for other devices to adjust their own working status and avoid RF conflicts with the device. Through this interface, the system can dynamically grasp the working frequency band range of the device, thereby providing accurate data support for subsequent RF management.

[0062] In a specific implementation, when the analysis result indicates that the time domain of the conflict source device is a pulse signal and the instantaneous operating frequency band is fixed, a second blocking timing interface is configured for the conflict source device.

[0063] Specifically, the second blocking timing interface is used to transmit a second amplitude of the level signal, which indicates whether the conflicting device is radiating electromagnetic waves within a fixed frequency band. Because the operating frequency band of these conflicting devices is relatively stable, the second blocking timing interface allows the system to simply and effectively determine whether the device is radiating within the fixed frequency band. When the level signal indicates that a device is radiating within the fixed frequency band, other devices can adjust their operating states based on this information to avoid conflict with the device's RF signal.

[0064] In another specific implementation, when the analysis result indicates that the time domain of the conflict source device is a continuous wave signal and the instantaneous operating frequency band is variable but the change is not frequent, a second compatible parameter interface is configured for the conflict source device.

[0065] Specifically, the second compatibility parameter interface is used to transmit the instantaneous operating RF bandwidth and frequency band of the conflicting device when it switches RF bands. Through this interface, the system can promptly monitor the frequency band switching status of the conflicting device and adjust the operating status of other devices to ensure RF compatibility across the entire system.

[0066] After completing the interface design for conflict source devices, the task priority of these devices is determined based on the current combat scenario. Understandably, different combat scenarios place varying demands on each conflict source device, so device priority needs to be determined based on the specific characteristics of the combat scenario. For example, during the pre-combat reconnaissance phase, electronic reconnaissance and countermeasures equipment may have a higher priority because it can provide critical intelligence information for combat operations. However, during the attack phase, radar and weapon system-related equipment may receive a higher priority to ensure accurate target strikes.

[0067] Furthermore, a corresponding radio frequency management strategy is formulated for the conflict source device using the interface design and task priority of the conflict source device, so as to perform corresponding radio frequency compatibility management on the conflict source device based on the radio frequency management strategy.

[0068] Specifically, in the current combat scenario, based on the combat scenario, a conflict source device that meets the preset high-priority task conditions is determined as a first conflict source device, and based on the combat scenario, a conflict source device that meets the preset low-priority task conditions is determined as a second conflict source device. Furthermore, the instantaneous operating frequency band of the second conflict source device is monitored, and a monitoring result is obtained.

[0069] If the monitoring result indicates that the instantaneous operating frequency band of the second conflict source device meets the preset frequency band fixing condition, a first time window for time-sharing operation is established according to the timing characteristics of the first conflict source device. The first conflict source device and the second conflict source device operate in time-sharing according to the first time window to determine the first radio frequency management strategy.

[0070] If the monitoring result indicates that the instantaneous operating frequency band of the second conflict source device meets the preset frequency band variable condition, the instantaneous operating radio frequency bandwidth and radio frequency band of the first conflict source device are sent to the second conflict source device based on the interface design, so that the instantaneous operating frequency band of the second conflict source device is changed to an instantaneous operating frequency band outside the instantaneous operating frequency band range of the first conflict source device, so as to determine a second radio frequency management strategy.

[0071] It should be noted that in this situation, the signal transmitted by the second conflict source device can easily interfere with the normal operation of the first conflict source device. By prohibiting the second conflict source device from radiating electromagnetic waves within the first conflict source device's instantaneous operating frequency band and switching it to radiating electromagnetic waves in other frequency bands, this effectively prevents the second conflict source's signals from causing radio frequency interference in that frequency band on the first conflict source device, ensuring that the first conflict source device can accurately obtain the target signal information it needs. For example, when an electronic jammer is jamming a target in a certain frequency band, radar and other potentially interfering devices are prohibited from transmitting signals in that frequency band. This ensures that the electronic jammer can capture information about the target radar in real time, dynamically adjust its jamming strategy, and efficiently complete the electronic jamming mission. The radar operates in a different frequency band, ensuring its normal operation. Furthermore, the electronic jammer's reception is wide-band, and notching the radar's instantaneous transmission frequency band effectively prevents radar radiation from interfering with the electronic jammer's reception and causing false radar target signals. This also ensures the radar's normal detection function.

[0072] An electromagnetic wave receiving device and an electromagnetic wave sending device are determined in the conflict source device. If the instantaneous operating frequency band of the electromagnetic wave receiving device meets the preset broadband condition, the electromagnetic wave receiving device performs notch processing on the instantaneous operating frequency band of the electromagnetic wave sending device to determine a third radio frequency management strategy.

[0073] Furthermore, during the process of transmitting the instantaneous operating RF bandwidth and RF frequency band of the first conflict source device to the second conflict source device based on the interface design, the blocking timing of the first conflict source device is transmitted to the second conflict source device, so that the second conflict source device can determine a second time window based on the blocking timing and perform the corresponding preset notching processing operation. Specifically, the blocking timing reflects the time pattern of the radiation of the first conflict source device. Based on this timing information, the second conflict source device can notch the corresponding frequency band within a specific time period to avoid interference with the signal radiated by the first conflict source device.

[0074] Finally, corresponding radio frequency compatibility management is performed on the conflict source device based on the first radio frequency management policy, the second radio frequency management policy, and the third radio frequency management policy.

[0075] As can be seen above, in an electronic warfare drone system, the present invention first uses preset electromagnetic field simulation software to conduct simulations, combining the antenna radiation models and body shape of each drone's frequency-using devices. The spatial isolation and signal strength obtained from this simulation are used to identify conflicting devices within each frequency-using device. These conflicting devices are those whose transmit and receive frequency bands meet the pre-set similarity criteria. Next, the time and frequency domain characteristics of the conflicting devices are analyzed to obtain analysis results. Finally, based on these analysis results, the interface design for the conflicting devices is determined. Furthermore, a radio frequency management strategy is formulated based on the current combat scenario and this interface design. Using this radio frequency management strategy, appropriate radio frequency compatibility management is implemented for the conflicting devices. This improves the radio frequency compatibility of frequency-using devices within the electronic warfare drone system and, to a certain extent, enhances the user experience.

[0076] The technical solutions of the embodiments of the present invention are described in detail below in conjunction with specific application scenarios.

[0077] Specifically, during the electromagnetic simulation process, the antenna radiation model of the entire aircraft's antenna and the fuselage's exterior shape are input into HFSS software (an electromagnetic field simulation software) for electromagnetic simulation to determine the conflict source device, obtain the spatial isolation of the conflict source device, and obtain the signal strength of the signal radiated by the interference source to the sensitive source device.

[0078] Next, analyze the electromagnetic time-frequency characteristics of the conflict source device. For conflict source devices with pulsed signals and rapidly varying frequency domains, such as radar, electronic reconnaissance and countermeasures equipment, and self-defense equipment, a first lockout timing interface and a first compatibility parameter interface must be designed. The first lockout timing interface transmits high and low levels indicating whether the device is radiating. The first compatibility parameter interface transmits the device's radiation center frequency band and radiated RF bandwidth, indicating the device's radiated RF parameters.

[0079] For conflict source devices that use pulse signals but have a fixed instantaneous operating frequency band, such as air traffic control transponders, only a second lockout timing interface needs to be designed. This interface transmits high and low levels to indicate whether the device is radiating in a fixed frequency band. Finally, for conflict source devices that use continuous wave signals and have a variable instantaneous operating frequency band but change infrequently, such as data link devices, which begin radiating upon operation but switch to different radiation bands when switching modes, a second compatible parameter interface needs to be designed to transmit the actual operating RF parameters radiated by the device.

[0080] When two devices, A and B, have frequency conflicts (also known as conflicting sources), their task priorities must be determined. If, in a given scenario, A (the first conflicting source) has a higher priority than B (the second conflicting source), the blocking timing interface and RF compatibility interface must be designed based on the respective characteristics of A and B.

[0081] During the integrated radio frequency management process, if receiver B's instantaneous operating frequency band is determined to be fixed, the operator is prompted with the message: "B and A are sharing a time window." If receiver A's instantaneous operating frequency band is variable, A's compatibility parameters are sent to receiver B. Upon receiving this information, receiver B switches to a different frequency band, and receiver A notches B's instantaneous operating frequency band. Due to a certain degree of spatial isolation, after antenna coupling, the signal power reaching receiver A is reduced, falling below the receiver's detection level. Therefore, this radio frequency management strategy effectively resolves radio frequency conflicts between receivers A and B.

[0082] Accordingly, see Figure 2 As shown, an embodiment of the present invention provides a radio frequency compatibility device, including:

[0083] The device determination module 11 is configured to perform a simulation in an electronic warfare UAV system based on preset electromagnetic field simulation software, the antenna radiation model of each frequency-using device of the UAV, and the body shape, and to determine a conflict source device among each frequency-using device using the spatial isolation and signal strength obtained from the simulation; wherein the conflict source device is a device whose transmitting and receiving frequency bands between the frequency-using devices meet a preset frequency band similarity condition; the preset frequency band similarity condition is a condition indicating that the transmitting and receiving frequency bands overlap;

[0086] As can be seen from the above, the present invention performs simulation in the electronic warfare UAV system with the help of preset electromagnetic field simulation software, the antenna radiation model of the UAV and the body shape. Based on the simulation results and the signal strength during the simulation, the conflict source device in each frequency-using device is determined. Next, the spatial isolation of the conflict source device is determined, and its electromagnetic time domain and frequency domain characteristics are analyzed to obtain the analysis results. Finally, the interface of the conflict source device is designed according to the analysis results, and a radio frequency management strategy is formulated in combination with the interface design, spatial isolation and the current combat scenario, and the radio frequency compatibility management of the conflict source device is performed through this strategy. In this way, the present invention can improve the radio frequency compatibility of the frequency-using equipment in the electronic warfare UAV system and enhance the user experience to a certain extent.
