In describing the embodiments, if it is determined that a detailed description of related prior art could unnecessarily obscure the essence of the embodiments, such detailed description is omitted.

[0025] FIG. 1 is a schematic diagram showing the configuration of a drone system for drone tracking and jamming according to one embodiment.

[0026] Referring to FIG. 1, a drone system (100) for drone tracking and jamming may be configured to include a tracking unit (110), a jamming unit (120), a jamming signal inverse phase cancellation unit (130), an antenna unit (140), a control unit (150), and a drone radio wave absorption structure unit (160). In addition, it may be configured to include various other components such as a communication module, a display module, and a driving circuit. At this time, each component may be combined with each other to be implemented as one, or some components may be omitted.

[0027] A drone system (100) for tracking and jamming drones is a system that tracks unauthorized drones when they are detected and neutralizes them by interfering with their normal operation through radio jamming of drones within a certain distance, and can be implemented in the form of a drone for tracking and suppressing drones.

[0028] The tracking unit (110) can track the first drone based on the position, speed, and direction of the first drone when the first drone is detected.

[0029] That is, the tracking unit (110) can analyze the location, speed, flight path, and direction of movement of the detected first drone in real time and continuously track the first drone according to the analysis results.

[0030] When the jamming unit (120) confirms through tracking the first drone that the first drone is located within a reference distance, it processes to transmit a jamming signal through the antenna unit (140) in the direction where the first drone is located, thereby interfering with the normal operation of the first drone. Here, the reference distance may be set differently depending on the embodiment, for example, it may be set to 100m.

[0031] That is, the jamming unit (120) processes the first drone to transmit a highly directional jamming signal through the antenna unit (140) in the direction where the first drone is located when it is confirmed that the first drone has entered within a reference distance based on the tracking result of the first drone. By doing so, it can induce interference with the drone's control signal reception, location recognition, video transmission functions, etc., thereby interfering with or neutralizing the normal operation of the first drone.

[0032] The jamming signal inverse phase cancellation unit (130) can cancel the self-jamming signal by adding an inverse phase signal to the receiver to prevent the jamming signal transmitted from the antenna unit (140) from being input to the receiver and jamming the drone system (100) itself for drone tracking and jamming.

[0033] The jamming signal reverse phase cancellation unit (130) can generate and transmit a reverse phase correction signal to cancel the jamming signal transmitted through the antenna unit (140).

[0034] That is, the jamming signal inverse phase cancellation unit (130) can process the jamming signal to be canceled by analyzing characteristics such as strength, phase, and direction of the jamming signal to suppress unnecessary radio interference caused by the jamming signal transmitted through the antenna unit (140), and generating a correction signal having an inverse phase relationship with it and inducing it to be combined with the jamming drone receiver.

[0035] The jamming signal reverse phase cancellation unit (130) is configured to have a structure that combines the reverse phase signal with the receiving antenna, and for this purpose, the jamming signal reverse phase cancellation unit (130) may be configured to include a second antenna that receives a correction signal, and a detailed description of the second antenna will be described later with reference to FIG. 3.

[0036] The second antenna may be positioned at a different location from the first antenna, which is a transmitting antenna included in the antenna section (140), and may be configured to combine with an inverse phase correction signal of the jamming signal transmitted from the first antenna so that the jamming signal transmitted from the first antenna is not received by the second antenna or is reduced.

[0037] The antenna section (140) can operate as a miniaturized, back lobe attenuated, multi-band, high-gain antenna.

[0038] That is, the antenna section (140) may adopt a conical (radiating) structure antenna element for multi-band and miniaturization, and may adopt a stacked strip structure to reduce back lobe (back radiation). At this time, the antenna section (140) may have characteristics such as miniaturization, back lobe (back radiation) attenuation, high gain, and multi-band.

[0039] Specifically, the antenna section (140) needs to be miniaturized so that it can be mounted on a drone and the back lobe (back radiation) needs to be reduced. To achieve miniaturization, a conical antenna element is adopted and the antenna can be designed with a strip (stacked) structure. To reduce the back lobe (back radiation), the antenna can be designed with a strip (stacked) structure. Through this, the antenna section (140) can have characteristics such as miniaturization, back lobe attenuation, multi-band, and high directivity.

[0040] The antenna section (140) may be configured to include a first antenna that transmits a jamming signal, and a detailed description of the first antenna will be provided later with reference to FIG. 2.

[0041] The control unit (150) may be configured to perform all or part of the computational function, storage / reference function, input / output function, and control function that a conventional computer has.

[0042] The control unit (150) controls the operation of each of the tracking unit (110), the jamming unit (120), the jamming signal inverse phase cancellation unit (130), and the antenna unit (140), thereby controlling the overall operation of the drone system (100) for drone tracking and jamming.

[0043] The control unit (150) can be connected to an external device through a communication network. Here, the communication network can be configured as a wired or wireless communication network and can be implemented in various forms to enable communication between servers and between a server and a terminal. At this time, the control unit (150) can be directly connected to the communication network to be directly connected to an external device, or it can be indirectly connected to an external device by being connected to the communication network through a communication module provided in the drone system (100) for drone tracking and jamming.

[0044] According to one embodiment, the control unit (150) may include a processor and a memory, the processor may perform at least one method described below with reference to FIGS. 5 and 6, and the memory may store a program in which the methods described below are implemented. In this case, the memory may be a volatile memory or a non-volatile memory.

[0045] The processor can execute a program and control a drone system (100) for drone tracking and jamming. The code of the program executed by the processor and the information required for program execution can be stored in memory.

[0046] The memory can store data necessary to control the operation of each component of the drone system (100) for drone tracking and jamming in the processor.

[0047] That is, the memory can store data, data being processed, processed data, pre-configured data, etc., for processing operations performed to control the drone system (100) for drone tracking and jamming in the processor.

[0048] Memory can typically provide the functions that memory performs and can operate under the control of a processor.

[0049] The drone radio wave absorption structure (160) may be equipped with a stealth function to block or absorb jamming signals transmitted from the first antenna from being radiated in the direction where the drone tracking and jamming drone system (100) is located.

[0050] The drone radio wave absorption structure (160) is configured so that jamming signals radiated from the first antenna are not unnecessarily reflected or spread in the rearward direction, thereby minimizing electromagnetic wave exposure of the drone system (100) for drone tracking and jamming, reducing the possibility of re-detection, and preventing radio wave interference with friendly equipment.

[0051] The drone radio wave absorption structure (160) may be configured to include at least one of an electromagnetic wave absorbing material, a metal shielding layer, and a wavelength-specific reflection control structure. In this case, the electromagnetic wave absorbing material is a material that effectively absorbs electromagnetic waves of a specific frequency band to minimize reflection to the rear, and a multilayer or dielectric-magnetic combination structure may be used. The metal shielding layer may be implemented as a layer that completely blocks or reflects electromagnetic waves so that they are not directly radiated in the rear direction using aluminum, copper, or a composite metal material. The wavelength-specific reflection control structure may include a periodic structure or a metamaterial pattern that performs the function of avoiding energy concentration in a specific direction by controlling the reflection angle or inducing scattering according to the wavelength.

[0052] The drone radio wave absorption structure (160) can protect the drone tracking and jamming system (100) itself by blocking or absorbing unnecessary rearward radiation of jamming signals through stealth functions, and can secure operational concealment and stability against the electromagnetic environment by suppressing the detection of the drone tracking and jamming system (100) by other equipment.

[0053] FIG. 2 is a drawing for explaining a first antenna composed of a stacked strip antenna according to one embodiment.

[0054] Referring to FIG. 2(a), the first antenna includes a stacked strip antenna formed by stacking a plurality of strip-shaped radiators in different layers, designed to transmit interference signals of multiple frequency bands with high directionality, and configured to adjust the signal magnitude toward the relative position of the drone targeted for jamming.

[0055] That is, the first antenna may be composed of a stacked strip antenna in which a plurality of strip-type radiators are stacked in different layers in the vertical direction. In this case, the stacked strip antenna is designed so that each radiator corresponds to a different frequency band, thereby enabling the simultaneous or selective transmission of jamming signals of multiple frequency bands with a single antenna structure, and can effectively induce interference on various frequency bands used in drone operation, such as GNSS signals (e.g., GPS, GLONASS, BeiDou), C2 links (control signals), and video transmission channels.

[0056] The first antenna is designed to have highly directional multi-band characteristics, and the radiation intensity can be dynamically adjusted according to the relative position of the drone.

[0057] Referring to Figures 2 (b) and (c), the first antenna is configured as a stacked strip antenna, which can transmit a jamming signal by concentrating it in the target direction, and can minimize radio interference to the drone system (100) for drone tracking and jamming.

[0058] The first antenna can simultaneously secure high power and high directional characteristics while minimizing size through a stacked strip antenna structure, making it useful for mounting on small equipment.

[0059] FIG. 3 is a drawing for explaining a second antenna receiving a correction signal according to one embodiment.

[0060] Referring to FIG. 3(a), a drone system (100) for drone tracking and jamming can receive a correction signal for self-anti-jamming while transmitting a jamming signal to an opponent drone to jam the opponent drone.

[0061] Referring to FIG. 3(b), the second antenna may be positioned at a different location from the first antenna and configured to receive an inverse phase correction signal for the jamming signal transmitted from the first antenna, thereby reducing unnecessary spreading or interference residue of the jamming signal transmitted from the first antenna.

[0062] That is, the second antenna is positioned at a different location from the first antenna transmitting the jamming signal, and can operate independently by taking into account the radiation direction, reverberation path, and energy distribution of the jamming signal transmitted from the first antenna.

[0063] The second antenna may be configured to induce cancellation of an interference signal in a specific direction or range by analyzing the phase, amplitude, frequency, etc. of a jamming signal transmitted from the first antenna in real time or receiving it from the control unit (150), and by generating and receiving a cancellation signal having an inverse phase to the signal.

[0064] The second antenna can suppress radio interference with the surrounding environment by preventing the high-power jamming signal of the first antenna from unintentionally spreading to the rear or side, and can ensure signal stability and minimize unnecessary energy consumption by reducing interference residue that may occur due to reflection by walls, structures, terrain, etc., and can more precisely control the jamming range and direction through phase correction and directional dispersion control between multiple antennas.

[0065] The second antenna can be implemented as a highly directional antenna, a patch antenna, a phased array antenna, etc., and is configured so that the phase, intensity, and radiation pattern can be adjusted in real time by the control unit (150).

[0066] FIG. 4 is a diagram showing the process of generating a correction signal according to one embodiment.

[0067] Referring to FIG. 4, a drone system (100) for drone tracking and jamming includes a receiving antenna that receives a base station signal x(n), and the signal received from this antenna can then be processed into a feedback signal. Here, the feedback signal is transmitted to a repeater output through a transmitting antenna via an isolation structure.

[0068] A drone system (100) for drone tracking and jamming may additionally be configured with an interference remover to remove the interference component when a jamming signal or an external interference signal is present. In this case, the interference remover may include an FIR filter, an adaptive algorithm, and a feedback loop for generating a correction signal.

[0069] Looking at the operation of the interference canceller, the received signal x(n) can be filtered through an FIR filter to generate an output y(n). At this time, the output y(n) is compared with the received signal to generate a residual signal e(n), which may represent the component where interference was not removed.

[0070] The residual signal e(n) is input to an adaptive algorithm for updating the filter coefficients W(n), where the FIR filter can be optimized in real time through LMS (Least Mean Squares), RLS (Recursive Least Squares), or other algorithms.

[0071] The residual signal e(n) is combined with the pilot signal, and an inverse phase correction signal is generated based on this signal and can be transmitted to the transmitting antenna via an amplifier.

[0072] The correction signal generated in this way is transmitted from the transmitting antenna and causes cancellation interference with the jamming signal, which can suppress the spread of interference to the outside or minimize the impact on surrounding systems.

[0073] As described above, the drone system (100) for drone tracking and jamming can implement a drone form that tracks and suppresses a drone based on a configuration such as a stacked strip antenna, stealth function, and cancellation through an inverse phase correction signal.

[0074] FIG. 5 is a flowchart illustrating the process of setting the strength of a jamming signal according to one embodiment.

[0075] Referring to FIG. 5, first, in step S501, the control unit (150) obtains the result of tracking the first drone from the tracking unit (110), and then, based on the result of tracking the first drone, can identify the position of the first drone at the first time as the first position. At this time, the first position can be identified as a 2D coordinate or a 3D coordinate.

[0076] In step S502, the control unit (150) can determine the distance to the first position as the first distance. At this time, the control unit (150) can determine the distance between the current position of the drone tracking and jamming drone system (100) and the first position as the first distance, and the current position of the drone tracking and jamming drone system (100) can be determined through a GPS module installed in the drone tracking and jamming drone system (100).

[0077] In step S503, the control unit (150) can check whether the first distance is shorter than the reference distance.

[0078] If it is confirmed in step S503 that the first distance is not shorter than the reference distance, after a certain period of time, the process can be repeated starting from step S501 to verify the position of the first drone.

[0079] If it is confirmed in step S503 that the first distance is shorter than the reference distance, in step S504, the control unit (150) may set the first value to a higher value within the first numerical range as the first distance increases. Here, the first numerical range may be set differently depending on the embodiment, for example, to a range of 0 to 100.

[0080] For example, the control unit (150) can set the first value to 10 if the first distance is confirmed to be 10m, and can set the first value to 20 if the first distance is confirmed to be 20m.

[0081] In step S505, the control unit (150) can set the first intensity to a stronger intensity within the intensity range as the first value increases. Here, the intensity range is a range of signal intensity that can be set differently depending on the embodiment, for example, to a range of 0dBm to 50dBm.

[0082] For example, the control unit (150) can set the first intensity to 5 dBm when the first value is confirmed to be 10, and can set the first intensity to 10 dBm when the first value is confirmed to be 20.

[0083] In step S506, the control unit (150) can control the transmission of a jamming signal of a first intensity in the direction where the first drone is located through the first antenna.

[0084] FIG. 6 is a flowchart illustrating the process of adjusting the strength of a jamming signal according to one embodiment.

[0085] According to one embodiment, each step illustrated in FIG. 6 can be performed after step S506.

[0086] Referring to FIG. 6, first, in step S601, the control unit (150) continuously obtains the result of tracking the first drone from the tracking unit (110), and then determines whether the first drone is operating normally at a second time point based on the result of tracking the first drone. Here, the second time point is a time point after the first time point, and normal operation of the first drone may mean that the first drone is maintaining a moving state without falling.

[0087] In step S602, the control unit (150) can determine whether the first drone is operating normally at the second time point, and as a result of determining whether the first drone is operating normally.

[0088] If it is confirmed at the second time point in step S602 that the first drone is not operating normally, in step S603, the control unit (150) determines that the first drone has crashed and can control the first antenna so that the jamming signal is no longer transmitted.

[0089] If it is confirmed in step S602 that the first drone is operating normally at the second time point, in step S604, the control unit (150) can confirm the position of the first drone at the second time point as the second position. At this time, the second position can be confirmed as a two-dimensional coordinate or a three-dimensional coordinate.

[0090] In step S605, the control unit (150) can determine the distance to the second position as the second distance. At this time, the control unit (150) can determine the distance between the current position of the drone system (100) for drone tracking and jamming and the second position as the second distance.

[0091] In step S606, the control unit (150) can set the second value to a higher value within the first value range as the second distance increases.

[0092] In step S607, the control unit (150) can determine the difference between the first time point and the second time point as the first time.

[0093] In step S608, the control unit (150) can set the first weight to a higher value within the first weight range as the first time is longer. Here, the first weight range may be set differently depending on the embodiment, for example, to a range of 1 to 2.

[0094] For example, the control unit (150) can set the first weight to 1.1 if the first time is confirmed to be 1 second, and can set the first weight to 1.2 if the first time is confirmed to be 2 seconds.

[0095] In step S609, the control unit (150) can calculate a third value by multiplying the second value by the first weight.

[0096] In step S610, the control unit (150) can set the second intensity to a stronger intensity within the intensity range as the third value increases.

[0097] In step S611, the control unit (150) can control the transmission of a jamming signal of a second intensity in the direction where the first drone is located through the first antenna.
