[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] The following is in conjunction with the appendix Figs. 1-3 This application provides a further detailed description. This application discloses a fixed detection and countermeasure device for unmanned aerial vehicles (UAVs). It includes a fixed support 1, with a direction-finding antenna 2 mounted at its top, enabling the antenna to perform 360° direction finding without obstruction from other devices. A detection device 3 and a countermeasure device 4 are mounted on the side of the fixed support 1. The detection device 3 has a detection antenna 301, and the countermeasure device 4 has a countermeasure antenna 401. The tops of both the detection antenna 301 and the countermeasure antenna 401 are lower than the direction-finding antenna 2 to prevent obstruction. The countermeasure device 4 includes a processing core 404. The direction-finding antenna 2 is electrically connected to the detection device 3, and the detection device 3 is also electrically connected to the processing core 404. The remote control signal of the UAV is acquired through the detection antenna 301, the UAV's position is acquired through the direction-finding antenna 2, and the UAV's flight trajectory is obtained through continuous monitoring. The detection device 3 analyzes the UAV's remote control signal to obtain the UAV's signal specification information and, combined with the UAV's flight trajectory, sends the preliminary analysis results to the processing core 404. When the integrated processing core 404 determines, based on the preliminary analysis results, that the drone should be countered, it drives the countermeasure antenna 401 to send an interference signal to interfere with the drone's remote control signal, thereby causing the drone to lose control.

[0018] The detection antenna 301 is an omnidirectional detection antenna 301, which is used to enhance the detection angle and maximize the detection of unmanned aerial vehicle signals in different directions. The type of countermeasure antenna 401 is not limited, and can be an omnidirectional countermeasure antenna 401 or a directional countermeasure antenna 401. The appropriate type of countermeasure antenna 401 can be set as needed according to the specific situation. The direction-finding antenna 2 is used to measure the position of the unmanned aerial vehicle, and provides the detection distance and angle of the unmanned aerial vehicle for the comprehensive processing core 404. The flight trajectory of the unmanned aerial vehicle is determined in the process of continuous detection. In this embodiment, the direction-finding antenna 2 is provided with 8 direction-finding units. More or fewer direction-finding units can be provided according to the actual situation and the purpose of direction-finding.

[0019] Specifically, the detection device 3 further includes a signal acquisition module 302, a spectrum analysis module 303, and a data processing and threat identification module 304 connected in sequence. The signal acquisition module 302 is electrically connected with the detection antenna 301 for receiving detection signals. The data processing and threat identification module 304 is electrically connected with the comprehensive processing core 404 for sending preliminary analysis results to the comprehensive processing core 404. The signal acquisition module 302 acquires radio frequency signals transmitted by the detection antenna 301 in real time, converts analog signals into digital signals through high-speed analog-to-digital conversion technology, and realizes digital processing of the signals. The spectrum analysis module 303 analyzes the signal spectrum using the FFT algorithm, extracts characteristic parameters such as frequency, bandwidth, and modulation mode, and accurately identifies the signal properties. The data processing and threat identification module 304 has an unmanned aerial vehicle feature database, which compares signal features to determine the unmanned aerial vehicle model and manufacturer. According to the monitoring data of the direction-finding antenna 2 and the flight trajectory algorithm, the flight path and behavior are analyzed to determine whether it is an intrusion threat. The threat level is output and the analysis results are sent to the comprehensive processing core 404.

[0020] Specifically, the countermeasure device 4 further includes a countermeasure module 403. The countermeasure module 403 is electrically connected with a power amplifier 402. The countermeasure module 403 is electrically connected with the comprehensive processing core 404. The power amplifier 402 is electrically connected with the countermeasure antenna 401. When the comprehensive processing core 404 determines that the threat level of the signal source reaches the set level according to the analysis results, the countermeasure module 403 generates a countermeasure signal according to the control of the comprehensive processing core 404. The countermeasure signal is amplified by the power amplifier 402 and then emitted by the countermeasure antenna 401 to interfere with the unmanned aerial vehicle.

[0021] Further, the outer surfaces of the detection device 3 and the countermeasure device 4 are provided with heat dissipation components. The heat dissipation components include conventional technical means such as heat dissipation fins or connected heat dissipation fans on the outer surfaces.

[0022] Further, the power supply, the direction-finding antenna 2, the detection device 3 and the countermeasure device 4 are electrically connected with the power supply, and the power supply is used for supplying power for the direction-finding antenna 2, the countermeasure device 4 and the detection device 3. The power supply can be powered by a battery to improve the independence of the utility model, or can be powered by an external power supply line through a power supply interface to improve the working continuity of the utility model. The power supply can be arranged at any position of the utility model according to actual conditions. In the embodiment, the power supply is integrated in the countermeasure device 4, which can be protected by the shell of the countermeasure device 4 and can be close to the comprehensive processing core 404 and the countermeasure module 403 to facilitate power supply for power-consuming equipment.

[0023] Further, the support 1 is provided with a fixed connection end 5 for connecting with an external structure. In the embodiment, the fixed connection end 5 is a connecting plate, and the connecting plate is provided with a threaded hole for threaded connection with the external structure.

[0024] Further, the comprehensive processing core 404 is electrically connected with a signal transceiver module for receiving an external control signal, and an operator can perform real-time control on the comprehensive processing core 404 through the signal transceiver module, such as presetting automatic countermeasure measures, manually starting or stopping the countermeasure measures or remotely updating a UAV feature database. The signal transceiver module can adopt wireless signals or wired signals according to actual conditions.

[0025] Working principle: after the utility model is fixed to a specific position, the power supply is turned on, preset threat levels are controlled through the comprehensive processing core 404, and a UAV feature database is input into the data processing and threat identification module 304. After starting, the detection antenna 301 of the detection device 3 continuously scans the airspace in all directions, and real-time receives a UAV remote control signal, image transmission data and navigation. The acquisition module digitizes the radio frequency signal, and the spectrum analysis module 303 extracts the signal features. The data processing and threat identification module 304 calls the database, compares the signal features with a UAV model library, analyzes the flight intention in combination with a trajectory algorithm, and sends the analysis result to the comprehensive processing core 404. The comprehensive processing core 404 judges the threat level of the UAV according to the analysis result. When the analysis result determines that the threat level of the UAV reaches the level required by the countermeasure, the comprehensive processing core 404 controls the countermeasure module 403 to generate a countermeasure signal, the countermeasure signal is amplified by the power amplifier 402 and is emitted through the countermeasure antenna 401 to interfere with the target UAV.

[0026] With the support of the signal transceiver module, the comprehensive processing core 404 can be remotely connected and controlled, the countermeasure device 4 can be started alone under specific requirements, and the countermeasure signal can be set to realize continuous countermeasures. In combination with a back-end monitoring platform and the like, UAV information including a model, a position, a countermeasure state and the like is uploaded to a remote control end in real time, which is convenient for remote scheduling and adapts to more practical scenarios.
