[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a signal interference device for deceiving UAVs using weak current information navigation. Background Technology

[0002] The widespread use of drones has also raised a series of security issues. In order to deal with these potential threats, it is urgent to develop effective anti-drone technologies. Among them, signal jamming devices for drone weak current information navigation deception have become one of the key means to ensure airspace security.

Especially in open large areas or when facing drones flying at high altitudes, the effect will be greatly reduced. Utility Model Content

The device utilizes advanced integration and miniaturization technology to highly integrate the various functional modules of the jamming device into a single interference control motherboard 1, reducing the size and weight of the device and facilitating its portability and transportation. The signal amplifier 11 is located at the rear center. The antenna interface 12 is located at the position. The signal transmitting mechanism 2 includes an antenna connector 21 threaded to the antenna interface 12. A connecting rod 22 is rotatably provided at the rear end of the antenna connector 21. Four phased array antennas 23 are arranged at equal angles at the top of the connecting rod 22. The whole adopts an optimized interference signal transmission structure design. It is equipped with a high-power transmission module and a multi-directional antenna structure. That is, the transmitting mechanism is connected to a signal enhancer 11. At the same time, the top of the transmitting mechanism is equipped with multi-directional phased array antennas 23 to enhance the signal transmission strength and directionality, expand the interference range, improve the signal transmission efficiency in different environments, and reduce signal attenuation.

[0023] A set of first mounting bases 15 are fixedly connected to the lower end of the signal receiving motherboard 13 and the signal processing motherboard 14, which are separated by one end. There are two first mounting bases 15 arranged symmetrically in front and behind. A second mounting base 16 is fixedly connected between the rear sides of the signal receiving motherboard 13 and the signal processing motherboard 14.

The signal receiving line can be connected to a multi-band signal receiving device, which can simultaneously receive signals from the global satellite navigation system commonly used by UAVs. The digital signal processor 19 of the signal processing motherboard 14 uses advanced digital signal processing technology to analyze the received signals in real time, identify the navigation system type, communication protocol, and flight status information of the target UAV. Based on the analysis results of the target UAV's navigation signals, the signal generation module inside the device uses a high-precision frequency synthesizer and digital signal processor 19 to generate a false signal that is extremely similar to the real satellite navigation signal. For the communication link between the UAV and the remote controller, the signal generation module generates false control command signals and return data signals, which are transmitted and received by the signal transmitting mechanism 2, thereby implementing interference and deception strategies.
