[0044] Considering that in existing technologies, common aircraft countermeasures mainly employ directional or omnidirectional jamming, which disrupts or interferes with the communication links of UAVs, such as remote control, image transmission, and navigation, by emitting radio signals in specific frequency bands, traditional equipment generally suffers from the following problems: limited jamming coverage, limited coverage angles for some devices, making it difficult to effectively jam aircraft in multiple directions; low component integration, complex wiring, low deployment efficiency, and poor reliability; and poor flexibility, lacking agile maneuvering capabilities.

[0045] Please see Figure 1 , Figure 1 One of the structural schematic diagrams of a foldable antenna directional UAV countermeasure device provided in this embodiment is as follows: Figure 1 As shown in the figure, the foldable antenna directional drone countermeasure device provided in this embodiment includes: a host 11, a main radio frequency antenna 12, at least one secondary radio frequency antenna 13, a rotating assembly 14, and a gimbal 15.

[0046] Specifically, the main radio frequency antenna 12 is fixed to the first side surface of the host 11; each secondary radio frequency antenna 13 is connected to the second side surface of the host 11 through a rotating assembly, one end of the rotating assembly 14 is rotatably connected to the second side surface, and the other end is rotatably connected to the secondary radio frequency antenna 13; the main radio frequency antenna 12 is electrically connected to the radio frequency module in the host 11 through an internal cable, and the secondary radio frequency antenna 13 is electrically connected to the radio frequency module through an external cable; the gimbal 15 is connected to the bottom of the host 11's casing to drive the host to rotate.

[0047] Here, the main unit 11 is the core structural frame of the entire device, used to integrate internal components such as the radio frequency module, power supply module, and control circuit module. The main unit 11 has a cubic shape with multiple sides to facilitate the installation of different components and the layout of interfaces. The first side surface of the main unit is used to install the main radio frequency antenna, the second side surface is used to connect the secondary radio frequency antenna, the bottom surface is used to install the gimbal structure, and the third side surface usually has power supply and communication interfaces and radio frequency signal output interface groups.

[0048] It should be noted that the first side surface and the second side surface are different side surfaces. Preferably, the direction in which the foldable antenna directional UAV countermeasure device needs to transmit interference signals during operation is taken as the forward direction. The first side surface is the front side surface of the host 11, and the second side surface is the left and right side surfaces of the host 11.

[0049] Here, the main radio frequency antenna 12 is mounted on the first side surface of the main unit 11. It is a fixed structure and is connected to the internal radio frequency module via internal cables. The main radio frequency antenna 12 is mainly used to transmit CW sweep frequency jamming signals. Its coverage direction is directly in front of the main axis, and it has a high transmission gain, which is used to jam frontal target aircraft.

[0050] Here, there can be one or more secondary RF antennas 13, all mounted on the second side surface of the main unit 11 via a rotating assembly 14. The secondary RF antennas 13 are structurally adjustable antennas, their main function being to extend the lateral range of interference coverage, forming an angle complement with the main RF antenna 12 to improve spatial interference capability. Each secondary RF antenna is connected to the RF module inside the main unit via an external RF cable for flexible maintenance and disassembly.

[0051] Preferably, the rotating assembly 14 includes a plurality of rotating members 141, which are rotatably connected in sequence; the connecting ends between the rotating members 141 and the connecting ends between the rotating members 141 and the host 11 can rotate in the horizontal circumferential direction.

[0052] Specifically, the rotating assembly 14 connects the main unit 11 and the secondary radio frequency antenna 13, and includes multiple rotating components 141. These rotating components 141 can be universal joints, multi-segment robotic arms, or horizontal rotation mechanisms, etc. This assembly has a structure with rotatable connections at both ends. One end is fixedly mounted on the second side surface of the main unit 11 and can be horizontally rotated to adjust the deployment angle of the secondary radio frequency antenna 13. The other end is connected to the secondary radio frequency antenna 13 and can adjust its orientation. Through the arrangement of these rotating components 141, the secondary radio frequency antenna 13 can be positioned and adjusted along the horizontal or elevation angle, improving the accuracy of target coverage.

[0053] Furthermore, the gimbal 15 is mounted on the bottom of the main unit 11 and is fixedly connected to the housing of the main unit 11 via a bottom adapter flange. The gimbal 15 integrates components such as a drive motor, angle sensor, and attitude controller, enabling omnidirectional rotation control of the main unit 11. The gimbal 15 is equipped with a DC power supply interface and a control signal interface, used for power supply and receiving control commands, respectively. Through the precise control of the gimbal 15, the main unit 11 can quickly aim at and track aircraft targets according to a preset direction.

[0054] exist Figure 1 Based on this, please refer to Figure 2 , Figure 2 This is the second schematic diagram of a foldable antenna directional UAV countermeasure device provided in this embodiment: Figure 2 As shown in the illustration, this embodiment provides a foldable antenna directional UAV countermeasure device comprising: a main unit 11, a main radio frequency antenna 12, at least one secondary radio frequency antenna 13, a rotating assembly 14, and a gimbal 15. The main unit 11 includes the radio frequency module 111, a radio frequency module controller 112, a power supply and communication interface 113, and a radio frequency signal output interface group 114. The secondary radio frequency antenna 13 is provided with a radio frequency signal input interface group 131. The base of the gimbal 15 is provided with a gimbal DC power supply interface 151 and a gimbal control signal interface 152, and also with a power supply and communication adapter interface 153.

[0055] Specifically, one end of the RF module controller 112 is electrically connected to the power supply and communication interface 113 of the host 11, and the other end is electrically connected to the control terminal of the RF module 111; the signal output terminal of the RF module 111 is electrically connected to the main RF antenna 12 and the RF signal output interface group 114 of the host 11, respectively; the power supply and communication interface 113 and the RF signal output interface group 114 are located on the third side surface of the host 11. The secondary RF antenna 13 is provided with an RF signal input interface group 131; the RF signal input interface group 131 is electrically connected to the RF signal output interface group 114 via an external cable.

[0056] It should be noted that the RF module controller 112 consists of multiple relays, which are used to control the power supply of the RF module 111. The RF module controller 112 receives the control signal transmitted by the PTZ through the power supply communication interface 113 and then triggers the corresponding relay to close, so as to control the operation of the corresponding RF module 111.

[0057] Here, the RF signal output interface group 114 includes multiple RF signal output interfaces, each corresponding to a preset frequency band; the RF signal input interface group 131 includes multiple RF signal input interfaces, each corresponding to a preset frequency band; the RF signal output interface is electrically connected to the RF signal input interface with the same preset frequency band via an external cable.

[0058] It should be noted that the third side surface can be different from or the same as the first and second side surfaces. Preferably, the direction in which the foldable antenna directional UAV countermeasure device needs to transmit interference signals during operation is taken as the forward direction, and the third side surface is the rear side surface of the host 11.

[0059] The base of the gimbal 15 is equipped with a gimbal DC power supply interface 151 and a gimbal control signal interface 152; the gimbal is also equipped with a power supply and communication adapter interface 153, which is electrically connected to the gimbal controller in the gimbal. The power supply and communication adapter interface 153 is electrically connected to the power supply and communication interface 113 of the host 11 through an external cable.

[0060] It should be noted that both the power supply and communication adapter interface 153 and the power supply and communication interface 113 include power supply connection terminals for power supply and signal transmission connection terminals for signal transmission. The cable used to connect the two can be a six-core cable, with four cores for power supply and two cores for signal transmission.

[0061] In practical implementation, the radio frequency module 111 is the core interference signal generation unit of the foldable antenna directional UAV countermeasure device. Its main components include a signal source (frequency synthesizer such as ADF4356) to generate a radio frequency carrier signal covering a preset frequency band, supporting wide-band frequency tuning, fast response, and high frequency accuracy; an FPGA-integrated digital waveform controller or DDS (direct digital synthesizer) to modulate the interference signal onto the carrier, supporting multiple interference modes such as AM / FM / pulse, and generating interference waveforms with specific structures; a high-linearity radio frequency power amplifier module (such as GaN power amplifier devices) to amplify the modulated radio frequency signal and output a high-intensity interference wave to ensure effective interference over long distances; a PIN diode switch matrix or multi-channel radio frequency relay to select and switch the multi-band output path, sending different frequency band signals to the main radio frequency antenna or the secondary radio frequency antenna respectively; and a bandpass filter, a low-pass filter, and a ring isolator to suppress clutter, intermodulation, and echo interference, improving signal purity and system reliability.

[0062] Optionally, the gimbal controller is the core component used to control the gimbal's attitude (azimuth and pitch angles). It can be a high-performance, low-power embedded microcontroller (such as the STM32F4 series) used to receive host commands, parse gimbal control signals, calculate servo control parameters in real time, and output control commands to the drive module.

[0063] As one possible implementation, the foldable antenna directional drone countermeasure device also includes an IP control box 16, which can be found in the following description. Figure 3 , Figure 3 This is a schematic diagram of the structure of an IP control box 16 provided in this embodiment. The IP control box 16 is provided with a signal converter 161, and its outer surface is provided with an AC power input interface 162, an IP signal input interface 163, a 458 signal output interface 164, and a DC power output interface 165.

[0064] Specifically, the data input terminals of the signal converter 161 are electrically connected to the AC power input interface 162 and the IP signal input interface 163, respectively; the data output terminals of the signal converter 161 are electrically connected to the 458 signal output interface 164 and the DC power output interface 165, respectively. The DC power output interface 165 is electrically connected to the pan-tilt head DC power supply interface 151 via an external cable; the 458 signal output interface 164 is electrically connected to the pan-tilt head control signal interface 152 of the pan-tilt head 15 via an external cable. The signal converter 161 is used to convert AC power to DC power and to convert IP control signals to 458 control signals.

[0065] Here, the IP signal input interface 163 is connected to a remote computer that controls the foldable antenna directional drone countermeasure device via a network cable, and receives IP control signals sent by the computer. The signal converter 161 converts the IP control signals into 458 control signals that the foldable antenna directional drone countermeasure device can recognize.

[0066] The following is a detailed explanation of the usage process of the foldable antenna directional drone countermeasure device: Unfold the rotating assembly 14 to align the secondary RF antenna 13 with the primary RF antenna 12; securely connect the RF signal output interface group 114 on the main unit 11 to the secondary RF antenna 13 via an RF cable; securely connect the gimbal 15 to the power supply and communication interface 113; securely connect the DC power output interface 165 and 458 signal output interface 164 of the IP control box 16 to the gimbal DC power supply interface 151 and gimbal control signal interface 152 using two sets of 4-core cables; connect one end of the power cord to the mains input interface 162 of the IP control box 16 and the other end to the mains power, powering on the gimbal 15 and the main unit 11 and performing a self-test; connect the IP signal input interface 163 of the IP control box 16 to the PC via a network cable, start the client software, and the software sends the operation... The command is transmitted to the signal converter 161 via the network cable. After receiving the command, the signal converter 161 converts it into a 485 signal and sends it to the gimbal 15. After receiving the signal, the gimbal 15 executes the corresponding rotation action and sends a signal to the radio frequency module controller 112. After receiving the signal, the radio frequency module controller 112 automatically opens the corresponding channel circuit. The radio frequency module 111 on the corresponding channel starts to work. The radio frequency module 111 uses CW frequency sweep technology to generate radio interference signals. The basic radio signal is modulated to the interference frequency band by the signal modulation module, and then amplified by a multi-stage amplification circuit to form electromagnetic waves with specific power. The electromagnetic waves generated by the radio frequency module 111 are transmitted to the corresponding main radio frequency antenna 12 or secondary radio frequency antenna 13 through the radio frequency line. The main radio frequency antenna 12 or secondary radio frequency antenna 13 amplifies the power of the electromagnetic waves and outputs them to the outside, thereby interfering with the aircraft.

[0067] This application provides a foldable antenna-based directional UAV countermeasure device, comprising a main unit, a main radio frequency antenna, at least one secondary radio frequency antenna, and a gimbal. The main radio frequency antenna is fixed to a first side surface of the main unit. Each secondary radio frequency antenna is connected to a second side surface of the main unit via a rotating assembly, one end of which is rotatably connected to the second side surface, and the other end of which is rotatably connected to the secondary radio frequency antenna. The main radio frequency antenna is electrically connected to a radio frequency module in the main unit via an internal cable, and the secondary radio frequency antenna is electrically connected to the radio frequency module via an external cable. The gimbal is connected to the bottom of the main unit's casing to drive the main unit to rotate.
