Embodiment Construction

[0028] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0029] According to the characteristics of the UAV signal, the present invention proposes a method for simultaneously interfering with the satellite navigation signal (1.5G), the remote control signal (2.4G or 5.8G) and the image transmission signal (2.4G or 5.8G), including the following technical measures: (1) A set of radio frequency measurement and direction finding processing system, which can realize the detection, reception and processing of UAV signals such as navigation signals, remote control signals and image transmission signals, and can quickly capture and identify long-distance UAV signals; (2) A set of three-channel blocking jamming equipment, which can confirm, locate and lock and track the UAV signal, and start the blocking jamming subsystem to separate the UAV navigation signal, remote control signal and image trans...

Abstract

The invention belongs to the technical field of electronic countermeasure, and discloses a portable three-channel blocking type interference device and method for a small unmanned aerial vehicle. Themethod comprises: a broadband antenna receiving an illegally invaded unmanned aerial vehicle signal, an unmanned aerial vehicle signal detection system carries out recognition and direction finding onthe received unmanned aerial vehicle signal, a three-channel blocking interference system further confirms, positions and locks and tracks the frequency and direction finding signal, then blocking interference signal processing is carried out, and finally the blocking interference signal is transmitted out through a three-in-one antenna. According to the invention, blocking interference signals generated by the three channels can be transmitted through the three-in-one three-frequency-band transmitting antenna, so that the three-in-one three-frequency-band transmitting antenna loses a flightcontrol instruction, an image transmission signal and a satellite positioning signal and cannot fly normally, and the control effects of return flight, landing and falling can be generated according to the design difference of the unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the technical field of electronic countermeasures, and relates to a method and a device for blocking and interfering with all satellite positioning signals. Interference method and device for remote control signal (2.4G or 5.8G) and image transmission signal (2.4G or 5.8G). Background technique [0002] With the increasing popularity of drones, it has become a very simple and easy thing for consumers to buy drones. Therefore, some unmanned aerial vehicles wantonly fly in unsafe places, causing great danger to the society. Similar to Events happen frequently. Not long ago, the Chongqing Airport was repeatedly disturbed by drones. More than 200 flights were diverted, cancelled and delayed, affecting tens of thousands of passengers. Before that, there have been incidents of drones interfering with civil aviation flights at airports such as Chengdu and Kunming Changshui. Internationally, just a few days ago, two drones interfere...
