[0069] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0070] Existing methods for suppressing drones rely on large-scale, crude containment, which lack precise control over containment location, frequency band, and intensity. Furthermore, traditional solutions are prone to collateral damage to legitimate frequency-using equipment within the area, compromising electromagnetic security in areas crucial for major events. To address these issues, this invention provides an intelligent decision-making method for precise control of unauthorized aircraft. Figure 1 This is a flowchart illustrating the intelligent decision-making method for precise prevention and control of illegal aircraft provided in an embodiment of the present invention. Figure 1 As shown, the method includes:

[0071] S100: Obtain electromagnetic parameter information of the aircraft;

[0072] It should be noted that the execution subject of this application embodiment is the key area electromagnetic safety dispatch and command system. The electromagnetic parameter information of the aircraft can be obtained through electromagnetic signal sensing nodes, etc., and the data information of the nodes can be called by the key area electromagnetic safety dispatch and command system.

[0073] Electromagnetic parameter information can include the aircraft's electrical signal information, latitude and longitude information, and time information. For example, it can include the aircraft's center frequency, level, field strength, bandwidth, modulation type, latitude and longitude, azimuth, initial occurrence time, signal occurrence time, signal type, target type, and data source. Specific electromagnetic parameter information is not limited to this.

[0074] S200: Calculates the threat level of an aircraft based on electromagnetic parameter information;

[0075] Once the electromagnetic parameters of the aircraft are acquired, the threat identification module in the key area electromagnetic security dispatch and command system determines the threat level based on these parameters. The determination method is not limited to threshold comparison or signal frequency change identification.

[0076] The procedure for determining the threat level of an aircraft is as follows:

[0077] (1) First, obtain the electromagnetic parameter information of the aircraft;

[0078] (2) Determine the weight of each electromagnetic parameter information and quantify each threat level indicator;

[0079] (3) Calculate the specific threat level based on the electromagnetic parameter information of the aircraft and the weight of each electromagnetic parameter information, and then classify the level according to the corresponding threat level indicators.

[0080] Furthermore, the threat level of an aircraft can be divided into different levels according to the degree of threat: Level 1, Level 2, Level 3, ..., Level N; it can also be divided into low, medium and high levels. The specific classification method can be determined according to actual needs, and the embodiments of the present invention do not limit it in this regard.

[0081] S300: Determine the appropriate execution strategy based on the threat level of the aircraft;

[0082] It should be noted that, in the embodiments of the present invention, the execution strategy may be routine monitoring, electromagnetic signal suppression, etc., depending on the threat level.

[0083] S400 monitors and controls the aircraft according to the corresponding execution strategy.

[0084] The intelligent decision-making method for precise control of illegal aircraft provided in this invention includes: acquiring electromagnetic parameter information of the aircraft; calculating the threat level of the aircraft based on the electromagnetic parameter information; determining the corresponding execution strategy based on the threat level of the aircraft; and monitoring and controlling the aircraft according to the corresponding execution strategy. That is, it first uses electromagnetic parameter information to determine the threat level of the aircraft, and then executes corresponding suppression strategies based on different threat level determination results, achieving precise suppression of illegal aircraft in various complex electromagnetic environments.

[0085] Optionally, the threat level of the aircraft includes: low threat, medium threat, and high threat.

[0086] Figure 2 A flowchart illustrating an intelligent decision-making method for precise prevention and control of illegal aircraft, as provided in another embodiment of the present invention, is shown below. Figure 2 As shown, determining the controller's execution strategy based on the aircraft's threat level includes:

[0087] S1. When the threat level is low, routine monitoring of the aircraft shall be carried out.

[0088] S2. When the threat level is medium, suppress the data transmission signals of the aircraft;

[0089] S3. When the threat level is high threat, suppress the aircraft in the GPS frequency band.

[0090] In this embodiment of the invention, routine monitoring may involve only monitoring the target aircraft's flight without any signal suppression. Data transmission signal suppression specifically refers to data transmission frequency band suppression. Global Positioning System (GPS) frequency band suppression includes: suppressive jamming and decoy jamming. Suppressive jamming involves the electromagnetic security dispatch and command system in key areas transmitting signals with power greater than the GPS signal power, preventing the target aircraft from obtaining information from GPS satellites. Decoy jamming involves transmitting signals similar to GPS signals, forcing the target aircraft to receive false navigation signals, thereby obtaining false position and other information.

[0091] Figure 3 A flowchart illustrating an intelligent decision-making method for precise prevention and control of illegal aircraft, as provided in another embodiment of the present invention, is shown below. Figure 3 As shown, step S2 includes:

[0092] S21. By suppressing the data transmission signal of the aircraft with the current intermediate power suppression, obtain the electromagnetic parameter information after intermediate power suppression processing;

[0093] Optionally, in this embodiment, the default intermediate suppression power is 40dBm. The specific value selection logic includes: when transmitting a high-power jamming signal to suppress an illegal aircraft, the transmission signal bandwidth needs to cover the entire frequency hopping band of the illegal aircraft. When the distance between the illegal aircraft and the jamming source is approximately 700 meters, a transmission power of 54dBm is required to effectively interfere with the illegal aircraft. When the distance is approximately 300 meters, a transmission power of 35dBm is required to effectively interfere with the illegal aircraft. When the distance is approximately 500 meters, a transmission power of 40dBm is required to effectively interfere with the illegal aircraft. To prevent excessive transmission power from causing accidental damage to legitimate frequency-using equipment within the security area, while ensuring effective interference with the illegal aircraft, 40dBm is ultimately selected as the default suppression power for the aircraft's data transmission frequency band.

[0094] S22. The threat level of the electromagnetic parameter information after the intermediate power suppression processing is identified to obtain the threat level after the intermediate power suppression processing.

[0095] S23. When the threat level after intermediate power suppression is low-level threat, routine monitoring of the aircraft shall be carried out.

[0096] S24. When the threat level after medium power suppression is medium threat, the aircraft is subjected to accidental damage assessment to obtain the accidental damage result.

[0097] Specifically, accidental damage assessment is generally conducted after the aircraft is in a state of controlled suppression.

[0098] In this embodiment, if the threat level after intermediate power suppression is intermediate threat, then the possibility of friendly fire is considered. The specific determination of the friendly fire result is explained in detail in the description of step S24 in the specification.

[0099] S25. When the threat level after intermediate power suppression is classified as high threat, the aircraft will be suppressed in the GPS frequency band.

[0100] Figure 4 A flowchart illustrating an intelligent decision-making method for precise prevention and control of illegal aircraft, as provided in another embodiment of the present invention, is shown below. Figure 4 As shown, step S3 includes:

[0101] S31. Obtain electromagnetic parameter information after advanced power suppression by suppressing the GPS frequency band of the current advanced power suppression aircraft;

[0102] S32. Perform threat level identification on the electromagnetic parameter information after advanced power suppression processing to obtain the threat level after advanced power suppression processing.

[0103] S33. When the threat level after advanced power suppression is classified as low threat, routine monitoring of the aircraft shall be conducted.

[0104] S34. When the threat level after advanced power suppression is advanced threat, the current advanced suppression power is increased by the preset first step length, and the increased power is used as the current advanced suppression power.

[0105] S35. Repeat steps S31-S35 until the aircraft's threat level is medium.

[0106] In this embodiment of the invention, the advanced suppression power is set to 10dBm by default. The specific logic for this value includes: GPS band suppression includes both suppressive jamming and decoy jamming. Suppressive jamming involves transmitting a signal with a power greater than the GPS signal power through the electromagnetic security dispatch and command system in key areas, preventing target aircraft from obtaining information from GPS satellites. Decoy jamming involves transmitting a signal similar to GPS, forcing the target aircraft to receive a false navigation signal, thereby obtaining false position and other information. Since the GPS signal transmission power of aircraft is in the range of 5dBm to 20dBm, to prevent excessive transmission power from causing accidental damage to legitimate frequency-using equipment within the security area, and to avoid interfering with illegal aircraft, 10dBm is ultimately selected as the default suppression power for the GPS band.

[0107] Furthermore, in this embodiment, the preset first step length can be gradually increased according to a specific value. Preferably, the preset first step length can be 2dBm.

[0108] Figure 5 A flowchart illustrating an intelligent decision-making method for precise prevention and control of illegal aircraft, as provided in another embodiment of the present invention, is shown below. Figure 5 As shown, step S24 includes:

[0109] S241. When the result of accidental injury is low, the current intermediate suppression power of suppressing the data transmission signal of the aircraft remains unchanged.

[0110] S242. When the accidental injury assessment result reaches the high accidental injury level, the current intermediate suppression power is reduced by the preset second step length, and the reduced power is used as the current intermediate suppression power.

[0111] S243. Use the current intermediate-level suppression power to suppress the aircraft's data transmission signal;

[0112] S244. The accidental injury assessment process is carried out on the aircraft after the intermediate power suppression process to obtain the accidental injury result;

[0113] S245. Repeat steps S241-S245 until the false alarm result is low false alarm.

[0114] In this embodiment, the preset second step length can be gradually reduced according to a specific value. Preferably, the preset second step length can be 4dBm.

[0115] In this embodiment of the invention, the process for determining the accidental injury assessment result is as follows:

[0116] (1) Treat interference sources such as interference devices and interference signals as abnormal targets and obtain parameter information of the interference sources;

[0117] (2) Calculate and save the working status of your own legitimate frequency-using equipment before the interference source transmits the interference signal;

[0118] (3) Calculate and save the working status of your own legitimate frequency-using equipment after the interference source transmits the interference signal;

[0119] (4) By comparing and calculating the working status of the legitimate frequency-using equipment before and after, the accidental damage assessment result is obtained. If the working status of the legitimate frequency-using equipment before and after is not much different, the legitimate frequency-using equipment is not affected or is only slightly affected, then the accidental damage result output is low; if the working status of the legitimate frequency-using equipment before and after is very different, the legitimate frequency-using equipment cannot work normally, then the accidental damage result output is high.

[0120] Among them, "our own legitimate frequency-using equipment" refers to other normally used equipment within the security area, such as monitoring equipment.

[0121] Optionally, the electromagnetic parameter information includes one or more of the following: center frequency, level, field strength, bandwidth, modulation type, latitude and longitude, azimuth, initial occurrence time, signal occurrence time, signal type, target type, and data source.
