Description

Technology Field

[0001] The following embodiments relate to a swarm drone defense system utilizing a beamforming antenna and a system providing a method for extending detection range. Background Technology

[0002] As the use of drones, known as unmanned aerial vehicles, is rapidly expanding, accidents threatening not only safety but also national security are on the rise.

[0003] In other words, cases of damage threatening safety, such as crimes and terrorism caused by the misuse of drones, are rapidly increasing, and as a countermeasure, the anti-drone industry designed to defend against illegal drones is growing in proportion to the growth of the drone industry.

[0004] Anti-drone technology is a technology that defends against (neutralizes) illegal drones used for purposes such as privacy invasion, crime, and terrorism; therefore, the process of detecting, identifying, and defending against drones is necessary for anti-drone operations.

[0005] Most existing drone detection methods utilize radar, but their short detection range and low detection rate result in insufficient time for identification and neutralization (jamming), posing a serious problem for neutralization and defense against drone swarms.

[0006] In addition, existing jamming methods employ a mechanical rotation method when illegal and offensive drones approach as a swarm, so they lack the time and are not suitable for defending against illegal drones approaching from all directions (360°).

[0007] Therefore, there is an increasing demand for the development of systems to resolve the aforementioned problems, and the implementation of related technologies is required. Prior art literature

[0009] According to one embodiment, the purpose is to provide a system that provides a swarm drone defense system utilizing a beamforming antenna and a method for extending the detection range.

[0010] The objectives of the present invention are not limited to those mentioned above, and other unmentioned objectives will be clearly understood from the description below. means of solving the problem

[0011] According to one embodiment, a system for providing a swarm drone defense system and a method for extending detection range using a beamforming antenna is provided, comprising: an antenna unit for receiving RF signals generated from multiple directions; a direction detection unit for detecting the direction of a drone based on the RF signals; and a jamming unit that, when a drone is detected to be in a first direction by the direction detection unit, transmits electromagnetic waves concentrated in the first direction through the antenna unit to support neutralization of the drone in the first direction.

[0012] The system providing a swarm drone defense system and a method for extending detection range using the beamforming antenna described above may further include: a radar and camera unit that performs precise detection of a drone in a first direction by focusing on the first direction when a drone is detected to be in a first direction by the direction detection unit; a transmission and reception switching unit that distinguishes between a detection mode and a jamming mode for the antenna unit; and a control unit that controls the operation of each of the antenna unit, the direction detection unit, the radar and camera unit, the jamming unit, and the transmission and reception switching unit.

[0013] In order to provide a process for a swarm drone defense system and a method for extending detection range using the beamforming antenna described above, the antenna unit operates in detection mode, the direction detection unit detects the approach of illegal and attack drones, and when a drone is detected, the direction detection unit transmits the drone detection information to the radar and camera unit, the antenna unit switches to jamming mode, the radar and camera unit precisely detects a drone in a designated direction through the radar, identifies whether an object in the designated direction is a drone through the camera, and when identified as a drone, transmits the drone detection information to the jamming unit, and the jamming unit supports the antenna unit to perform a jamming operation by beamforming it to appropriately jam the drone identified as a drone based on the drone detection information, and when the jamming unit determines that the drone identified as a drone is a swarm drone, it supports the defense of the swarm drone by electrically rotating the antenna unit. Effects of the invention

[0014] According to one embodiment, the antenna unit and the direction detection unit detect a drone at a long distance (10 km or more) and provide information to the radar, and the radar performs precise drone detection in the direction where the drone is detected, thereby increasing the detection range and providing sufficient response time for drone defense.

[0015] In addition, according to one embodiment, by utilizing a beamforming (direction detection) antenna, as shown in FIG. 1 (a), it can operate as an omnidirectional antenna during detection to detect drones from all directions in 360°, and as shown in FIG. 1 (b), it can operate as a directional antenna during jamming to create various radiation patterns, thus having an excellent effect in defending against swarm drones.

[0016] In addition, according to one embodiment, by applying an array antenna (an antenna of 5 elements) and adopting an electrical rotation method when changing the radiation direction, it takes a few milliseconds to rotate 360°, thereby overcoming the time limit of 12 seconds to rotate 360° with the conventional mechanical rotation method and obtaining the effect of simultaneously defending against drones attacking from any direction.

[0017] In addition, according to one embodiment, the antenna unit is used for both detection and jamming, and the transmitter and receiver units can also be shared by more than 80%, so the equipment is not complex, and thus it is possible to achieve great efficiency in installation and movement.

[0027] FIG. 2 is a schematic diagram showing the configuration of a swarm drone defense system and a detection range extension method providing system utilizing a beamforming antenna according to one embodiment.

[0028] Referring to FIG. 2, a system (100) providing a swarm drone defense system and a method for extending detection range using a beamforming antenna may be configured to include an antenna unit (110), a direction detection unit (120), a radar and camera unit (130), a jamming unit (140), a transmission and reception switching unit (150), and a control 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.

[0029] First, the antenna unit (110) can receive RF signals generated from multiple directions. To this end, the antenna unit (110) may be composed of a beamforming antenna, and the beamforming antenna can receive RF signals generated from 360° in all directions upon detection.

[0030] For example, the antenna unit (110) can be divided into three bands to operate as a broadband antenna, and each band's antenna is composed of five antenna elements. By controlling the control unit (160), the phase and magnitude of the energy input to each element are adjusted so that it operates as an omnidirectional antenna during detection and as a directional antenna during jamming, thereby enabling it to be implemented as a new type of antenna that performs detection and jamming simultaneously.

[0031] Each of the multiple antennas may be configured to include a receiving module for receiving RF signals and a transmitting module for transmitting jamming signals, and may also be configured to include various additional components necessary for performing the operation of the antennas.

[0032] The antenna section (110) serves to supplement the detection range of the radar and can also be used as a jammer antenna that emits a jamming signal.

[0033] That is, the antenna unit (110) is used for both detection and jamming. When the drone is detected to be in a specific direction by the direction detection unit (120), it informs the radar and camera unit (130) of the detection direction, and when returning to jamming mode, it can radiate a jamming signal in the direction indicated by the jamming unit (140). At this time, if the drone is a swarm, the antenna unit (110) can set the radiation mode to beamforming, which is an appropriate multi-beam form, to perform jamming in multiple directions simultaneously.

[0034] The antenna unit (110) communicates with detection and jammer equipment, and by organically repeating the above process, the defense of swarm drones can be optimized, and the problem of the radar's detection range being short (less than 5 km) can be compensated for, and the detection range can be extended to more than 10 km, which is double the original range.

[0035] The antenna unit (110) rotates electrically through a beamforming antenna during jamming, so that it can defend against a drone in the opposite direction within a few milliseconds.

[0036] The antenna unit (110) can be implemented as an antenna that is used for both detection and jamming, and may include a receiving module used for detection and a transmitting module used for jamming, and through the control of the control unit (160), it can perform various functions such as various radiation patterns, radiation directions, and electrical rotation in conjunction with the radar.

[0037] The direction detection unit (120) can detect the direction of the drone based on the RF signal received from the antenna unit (110). At this time, the direction detection unit (120) can detect the direction of the drone located at 10 km or more, exceeding the detection limit of 5 km of the existing radar.

[0038] For example, the antenna unit (110) can be configured to operate as an omnidirectional antenna when detecting a drone with multiple antennas configured by band, and the direction detection unit (120) can detect a drone at a long distance (10 km or more) based on the RF signal received from the antenna unit (110), thereby detecting illegal and attack drones in all directions of 360°.

[0039] That is, the direction detection unit (120) can detect the direction of a drone within a certain distance by checking whether a drone exists in each direction based on RF signals received from each of the multiple antennas configured by band.

[0040] When the direction detection unit (120) detects that a drone is in a specific direction, it can generate detection information and transmit the generated detection information to the radar and camera unit (130). Here, the detection information may include information regarding the direction, location, distance, etc. of the detected drone, and may further include information regarding the number of detected drones.

[0041] The radar and camera unit (130) can detect drones that are more precise and further away by detecting only the direction in which the drone is detected based on detection information received from the direction detection unit (120).

[0042] For example, when the drone is detected to be in a first direction by the direction detection unit (120), the radar and camera unit (130) can focus on the first direction and perform precise detection of the drone in the first direction. Here, the first direction is a specific direction in which the drone is detected to be by the direction detection unit (120), for example, east, west, south, north, northeast, southeast, southwest, northwest, etc.

[0043] That is, when the radar and camera unit (130) performs drone detection in multiple directions, the detection range is inevitably short because it detects a 360° range, and when it performs precision drone detection by focusing on a specific direction, the detection range can be extended because it detects only an angle range corresponding to the specific direction.

[0044] For example, the radar and camera unit (130) can detect up to 5 km when performing drone detection in multiple directions, and can detect up to 10 km or more when performing precision drone detection focused in a specific direction. Through this, the radar and camera unit (130) can perform precision drone detection focused in a specific direction, thereby increasing the detection range and identifying the approach of the drone more quickly, thereby securing sufficient response time for drone defense.

[0045] The radar and camera unit (130) may be configured to include a transmitting module that transmits electromagnetic waves and a receiving module that receives reflected waves, and may also be configured to include various additional components necessary for performing radar operations.

[0046] Additionally, the radar and camera unit (130) may be configured to include a camera that generates an image through shooting, and may also be configured to include various additional components necessary to perform the operation of the camera.

[0047] When an object in a designated direction is identified as a drone, the radar and camera unit (130) can transmit detection information to the radar and camera unit (130).

[0048] The jamming unit (140) can defend against a swarm of drones by appropriately performing beamforming based on detection information received from the radar and camera unit (130), the number of drones in the direction where the drone is detected, and the position of each drone, and radiating a jamming signal through the antenna unit (110).

[0049] For example, the jamming unit (140) can analyze the number of drones and the direction from which the drones are approaching based on detection information received from the radar and camera unit (130), and can neutralize the swarm of drones by appropriately performing beamforming through the antenna unit (110) to concentrate and radiate electromagnetic waves at the location of each drone, thereby radiating electromagnetic waves with an appropriate intensity. In addition, if swarm drones appear randomly from all directions (360°), the jamming unit (140) can support defense against the swarm drones by rotating the antenna unit (110) in an electrical rotational manner to rotate at intervals of several milliseconds. At this time, various known technologies can be utilized for the process of analyzing the number of drones and the location of each drone.

[0050] The transmission and reception switching unit (150) serves to distinguish between the detection mode of the antenna and the jamming mode of the antenna, and in the case of detection, it can support the detection of drones from all directions with an omnidirectional radiation pattern, and in the case of jamming, it can support the radiation of jamming signals only in a specific direction with a directional radiation pattern.

[0051] Additionally, the transmission and reception switching unit (150) can provide information on whether a drone has appeared to the radar and camera unit (130) in the event of detection, and receive detection information indicating the number and location of the drone from the radar and camera unit (130) in the event of jamming, and support the function of neutralizing the swarm of drones through the jamming unit (140).

[0052] The control unit (160) controls the operation of each of the antenna unit (110), direction detection unit (120), radar and camera unit (130), jamming unit (140), and transmission / reception switching unit (150), thereby controlling the overall operation of the system (100) that provides a swarm drone defense system and detection range extension method utilizing a beamforming antenna.

[0053] The control unit (160) can be configured to control the antenna detection mode, the antenna jamming mode, various antenna radiation patterns when in jamming mode, electrical rotation of the radiation direction, linkage with radar, linkage with camera, etc., and to perform all or part of the computational functions, storage / reference functions, input / output functions, and control functions of a normal computer.

[0054] The control unit (160) 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 (160) 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 system (100) that provides a swarm drone defense system and detection range extension method using a beamforming antenna.

[0055] According to one embodiment, the control unit (160) may include a processor and a memory, the processor may perform at least one method described below with reference to FIG. 3, 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.

[0056] The processor can execute a program and control a system (100) that provides a swarm drone defense system and a detection range extension method utilizing a beamforming antenna. The code of the program executed by the processor and the information required for program execution can be stored in memory.

[0057] The memory can store data necessary to control the operation of each component of the system (100) that provides a swarm drone defense system and a detection range extension method utilizing a beamforming antenna in the processor.

[0058] That is, the memory can store data, data being processed, processed data, pre-configured data, etc., for processing operations performed to control the swarm drone defense system and detection range extension method providing system (100) utilizing a beamforming antenna in the processor.

[0059] Memory can typically provide the functions that memory performs and can operate under the control of a processor.

[0060] FIG. 3 is a flowchart illustrating the process of providing a swarm drone defense system and a detection range extension method utilizing a beamforming antenna according to one embodiment.

[0061] Referring to FIG. 3, in step S301, the antenna unit (110) operates in detection mode, and the direction detection unit (120) can detect the approach of illegal and attack drones. At this time, the control unit (160) can control the antenna unit (110) to be set in detection mode, and the antenna unit (110) operates in detection mode to receive RF signals generated from multiple directions, and the direction detection unit (120) can detect the direction of the approaching drone based on the RF signals received from the antenna unit (110).

[0062] That is, the antenna unit (110) and the direction detection unit (120) can detect the direction of a drone intruding or attacking from all directions of 360°. At this time, the antenna unit (110) is set to a detection mode and operates, and the detection distance for illegal and attack drones can be up to 10 km.

[0063] In step S302, the direction detection unit (120) can transmit detection information of the drone to the radar and camera unit (130) when the drone is detected. Here, the detection information may include information regarding the direction, location, distance, etc. of the detected drone and information regarding the number of detected drones.

[0064] In step S303, the antenna unit (110) can be changed to a jamming mode. At this time, the control unit (160) can control the antenna unit (110) so that the setting is changed from detection mode to jamming mode.

[0065] In step S304, the radar and camera unit (130) can precisely detect a drone in a designated direction through the radar, identify whether an object in the designated direction is a drone through the camera, and if it is identified as a drone, transmit the detection information of the drone to the jamming unit (140).

[0066] That is, the radar and camera unit (130) can precisely detect a drone in the direction where the drone is detected through the radar, and identify whether an object in the direction where the drone is detected is a drone through the camera, and if the object is identified as a drone, the detection information of the drone can be transmitted to the jamming unit (140).

[0067] In step S305, the jamming unit (140) can support the antenna unit (110) in performing a jamming operation by beamforming it to properly jam a drone identified as a drone based on the detection information of the drone. At this time, the antenna unit (110) can operate as a directional antenna and transmit electromagnetic waves focused in the direction where the drone is detected.

[0068] In step S306, if the jamming unit (140) determines that the drone identified as a drone is a swarm drone, it can electrically rotate the antenna unit (110) to support defense against the swarm drone. At this time, the antenna unit (110) operates so that the array antenna rotates in an electrical rotation manner, thereby enabling defense against the swarm drone through the array antenna rotating at intervals of several milliseconds.

[0069] According to one embodiment, the jamming unit (140) can set the jamming intensity by the control of the control unit (160), and the process of setting the jamming intensity will be described in detail below.

[0070] First, the control unit (160) can determine the number of drones in the first direction at a first time point as the number of drones based on the result of performing precise detection of drones in the first direction. To do this, the control unit (160) can obtain the result of performing precise detection of drones in the first direction from the radar and camera unit (130).

[0071] Next, the control unit (160) can set the first value within the first numerical range to a higher value as the number of first drones increases. Here, the first numerical range may be set differently depending on the embodiment, for example, to a range of 0 to 100.

[0072] For example, the control unit (160) can set the first value to 10 when the number of the first drone is confirmed to be 1, and can set the first value to 20 when the number of the first drone is confirmed to be 2.

[0073] Next, the control unit (160) can identify the drone with the closest position among the drones in the first direction at the first time point as the first drone based on the result of performing precise detection on the drone in the first direction.

[0074] When the number of first drones is 1, the control unit (160) can identify the drone in the first direction as the first drone, and when the number of first drones is 2 or more, the drone identified as having the closest location as a result of comparing the positions of each drone in the first direction can be identified as the first drone. At this time, having the closest location may mean that the distance between the point where the swarm drone defense system and detection range extension method provision system (100) utilizing a beamforming antenna is installed and the drone is the shortest.

[0075] Next, the control unit (160) can confirm the position of the first drone at a first time point as the first position. At this time, the first position can be confirmed as the result of performing precise detection on the drone in the first direction or through the detection information of the drone, and, for example, can be confirmed as 2D coordinates, 3D coordinates, etc.

[0076] Next, the control unit (160) can determine the distance to the first position as the first distance. At this time, the control unit (160) can determine the distance between the point where the system (100) providing a swarm drone defense system and detection range extension method using a beamforming antenna is installed and the first position as the first distance.

[0077] Next, the control unit (160) can set the second value to a higher value within the second value range as the first distance becomes shorter. Here, the second value range may be set differently depending on the embodiment, for example, to a range of 0 to 100.

[0078] For example, the control unit (160) can set the second value to 10 if the first distance is confirmed to be 9 km, and can set the second value to 20 if the first distance is confirmed to be 8 km.

[0079] Next, the control unit (160) can calculate a third value by adding the first value and the second value.

[0080] Next, the control unit (160) can set the first intensity to a stronger intensity within the intensity range as the third 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 0 dBm to 50 dBm.

[0081] For example, the control unit (160) can set the first intensity to 10 dBm when the third value is confirmed to be 40, and can set the first intensity to 20 dBm when the third value is confirmed to be 80.

[0082] Next, the jamming unit (140) can transmit electromagnetic waves of a first intensity in a first direction through the antenna unit (110) to support neutralizing a drone in the first direction. At this time, the antenna unit (110) can operate in jamming mode to transmit electromagnetic waves of a first intensity in the first direction.

[0083] According to one embodiment, the jamming unit (140) can adjust the jamming intensity by controlling the control unit (160), and the process of adjusting the jamming intensity will be explained in detail below.

[0084] First, the control unit (160) can identify a point in time after a reference time from a first point in time as a second point in time. Here, the reference time may be set differently depending on the embodiment, for example, it may be set to 10 seconds.

[0085] Next, the control unit (160) can confirm the location of the first drone as a second location at the second time point if it detects that the first drone is continuously approaching based on the results of the precision detection of the drone in the first direction. At this time, the second location can be confirmed through the results of the precision detection of the drone in the first direction or through the detection information of the drone, and can be confirmed, for example, as 2D coordinates, 3D coordinates, etc. To this end, the antenna unit (110) is in a state of continuously transmitting electromagnetic waves of a first intensity in the first direction, and the radar and camera unit (130) is in a state of continuously performing precision detection of the drone in the first direction.

[0086] Next, the control unit (160) can determine the distance to the second location as the second distance. At this time, the control unit (160) can determine the distance between the point where the swarm drone defense system and detection range extension method providing system (100) utilizing a beamforming antenna is installed and the second location as the second distance.

[0087] Next, the control unit (160) can calculate a third distance by subtracting the second distance from the first distance.

[0088] Next, the control unit (160) can calculate the first speed by dividing the third distance by the reference time.

[0089] Next, the control unit (160) can set the first weight to a higher value within the first weight range as the second distance becomes shorter. Here, the first weight range may be set differently depending on the embodiment, for example, to a range of 1 to 2.

[0090] For example, the control unit (160) can set the first weight to 1.2 if the second distance is confirmed to be 5 km, and can set the first weight to 1.4 if the second distance is confirmed to be 4 km.

[0091] Next, the control unit (160) can set the second weight to a higher value within the second weight range as the first speed increases. Here, the second weight range may be set differently depending on the embodiment, for example, to a range of 1 to 2.

[0092] For example, the control unit (160) can set the second weight to 1.1 when the first speed is confirmed to be 10 m / s, and can set the second weight to 1.1 when the first speed is confirmed to be 20 m / s.

[0093] Next, the control unit (160) can calculate a fourth value by multiplying the third value by the first weight and the second weight.

[0094] Next, the control unit (160) can set the second intensity to a stronger intensity within the intensity range as the fourth value increases.

[0095] Next, the jamming unit (140) can transmit electromagnetic waves of a second intensity in a first direction through the antenna unit (110) to support neutralizing a drone in the first direction. At this time, the antenna unit (110) can operate in jamming mode to transmit electromagnetic waves of a second intensity in the first direction.
