Problems solved by technology

At present, the interference to the remote control data link of drones at home and abroad is mainly based on noise interference. By blocking the remote control data link and GPS navigation signal of the drone, the drone can return or land. There is no basis to crack the remote control data link. A device that reversely reconstructs the UAV remote control signal to seize the control of the UAV to realize the trapping of the UAV or realize the trapping of the UAV based on GPS spoofing interference

Abstract

The invention discloses an unmanned aerial vehicle trapping interception system based on electromagnetic interference and a trapping interception method thereof. The trapping interception system comprises a control host, a target searching tracking device and a trapping jammer. The target searching tracking device is used for detecting position information of a suspicious target in a protection airspace and video information and sending to the control host. The control host is used for determining whether the suspicious target is an unmanned aerial vehicle target according to the video information. If the suspicious target is the unmanned aerial vehicle target, according to the position information of the unmanned aerial vehicle target, the trapping jammer is controlled to emit an electromagnetic interference signal to the unmanned aerial vehicle target so as to realize trapping interception to the unmanned aerial vehicle target. In the invention, through using the electromagnetic interference signal, the trapping interception to the unmanned aerial vehicle is realized and soft killing trapping interception of the unmanned aerial vehicle is realized too. New defense means are provided for relieving a security threat caused by a low, slow and small unmanned aerial vehicle. And a secondary damage caused through using a traditional interception net, a laser and other hard killing interception modes is avoided.

Description

technical field [0001] The invention relates to the technical field of trapping and intercepting drones, in particular to a trapping and intercepting system and method for trapping and intercepting drones based on electromagnetic interference. Background technique [0002] In the field of low-speed and small UAVs, with the increasing improvement of micro-system technology and its manufacturing process, the electromechanical systems required in UAV systems continue to be miniaturized and miniaturized. At present, in addition to using traditional air defense weapons such as radar detection and missiles to fight against UAVs, countries in the world are also vigorously carrying out electronic warfare, network warfare, laser weapons and other UAV technology research and rapid development of equipment. At present, the interference to the remote control data link of drones at home and abroad is mainly based on noise interference. By blocking the remote control data link and GPS nav...
