[0014] The following will further describe the present utility model in conjunction with the drawings. It should be noted that this embodiment is based on the present technical solution and gives detailed implementation manners and specific operation processes, but the protection scope of the present utility model is not limited to this embodiment.

[0015] This embodiment provides a radio countermeasure detection system based on an unmanned aerial vehicle, as Figure 1 shown, including a monitoring payload, a ground station and an upper computer for monitoring countermeasure equipment;

[0016] The monitoring payload is carried on the unmanned aerial vehicle and includes a monitoring payload radio transceiver module, a monitoring payload power supply module, a communication detection module, a monitoring payload radio transceiver antenna and a data feedback module; the communication detection module and the monitoring payload radio transceiver antenna are both connected to the monitoring payload radio transceiver module, the communication detection module is connected to the data feedback module, and the data feedback module is wirelessly connected to the upper computer for monitoring countermeasure equipment; the monitoring payload power supply module is used to supply power to the monitoring payload radio transceiver module, the communication detection module, the monitoring payload radio transceiver antenna and the data feedback module;

[0017] The ground station includes a ground station radio transceiver module, a ground station radio transceiver antenna, a ground station power supply module, and a UAV remote control module; the ground station radio transceiver antenna and the UAV remote control module are both connected to the ground station radio transceiver module, and the ground station power supply module is used to supply power to the ground station radio transceiver antenna, the UAV remote control module, and the ground station radio transceiver module; the ground station radio transceiver antenna is used to receive signals from the monitoring payload radio transceiver antenna and send signals to the monitoring payload radio transceiver antenna.

[0018] It should be noted that both the monitoring payload radio transceiver module and the ground station radio transceiver module use LR1121 RF chips, and the monitoring payload power supply module provides power of 3V / 12V / 24V and uses adjustable power supplies such as MP1584EN for output. The ground station power supply module provides power of 12V / 24V. The communication detection module has an embedded operating system to implement communication frequency band parameter detection.

[0019] In this embodiment, there are multiple monitoring payload radio transceiver modules and ground station radio transceiver modules, and the communication frequency bands of each monitoring payload radio transceiver module are different. The communication frequency bands of each ground station radio transceiver module correspond one-to-one with the communication frequency bands of each monitoring payload radio transceiver module; each monitoring payload radio transceiver module is respectively connected to a corresponding monitoring payload radio transceiver antenna, and each ground station radio transceiver module is respectively connected to a corresponding ground station radio transceiver antenna.

[0020] In this embodiment, the data transmission module is wirelessly connected to the anti-jamming device monitoring host computer through 4G or LoRa.

[0021] In this embodiment, the monitoring payload further includes a data storage module, which is connected to the monitoring payload radio transceiver module and the communication detection module and is powered by the monitoring payload power supply module. The data storage module is mainly used to store the communication data between the monitoring payload and the ground station and the communication frequency band parameter data detected by the communication detection module.

[0022] In this embodiment, the monitoring payload further includes a GNSS positioning module, which is used to obtain the position data of the monitoring payload, is connected to the monitoring payload radio transceiver module, and is powered by the monitoring payload power supply module.

[0023] The working principle of the above radio anti-jamming monitoring system is as follows:

[0024] The monitoring payload is wirelessly connected to the ground station through a radio transceiver module. The radio transceiver module of the monitoring payload on the UAV sends the UAV's signals to the ground station and receives the UAV remote control signals from the ground station through the monitoring payload radio transceiver antenna. The ground station radio transceiver module of the ground station transmits the UAV remote control signals from the ground station to the UAV and receives the UAV's signals through the ground station radio transceiver antenna, thereby realizing the transmission of UAV remote control information, the UAV's position information, etc. between the UAV and the ground station. During the detection and analysis of the UAV countermeasure device, all the monitoring payload radio transceiver modules work simultaneously (so that multiple groups of test data can be collected in a single test, simplifying the workload). The communication detection module obtains the parameters of each communication frequency band (such as RSSI, SNR, etc.) and transmits them to the upper computer of the countermeasure device monitoring through the data transmission module.

[0025] The data transmission module communicates with the upper computer of the countermeasure device monitoring through 4G or LoRa. The parameter information of each communication frequency band collected by the communication detection module is transmitted to the upper computer of the countermeasure device monitoring through the data transmission module. When conducting the performance detection and analysis of the countermeasure device, the upper computer of the countermeasure device monitoring can obtain the parameter information of each communication frequency band before and after the countermeasure device is turned on, evaluate the change in the communication quality of each communication frequency band before and after the countermeasure device is turned on, thereby realizing the quantitative evaluation of the performance of the countermeasure device, reducing human judgment, and improving the accuracy and efficiency of the performance evaluation of the countermeasure device.

[0026] Specifically, after the upper computer of the countermeasure device monitoring collects the parameters of the UAV communication channel and aligns them with the working time of the UAV countermeasure device, it can record the change trend of the communication quality of the UAV's communication frequency band before and after the countermeasure device is turned on.

[0027] For those skilled in the art, various corresponding changes and deformations can be given according to the above technical solutions and concepts, and all these changes and deformations should be included in the protection scope of the claims of this utility model.
