Drone defense systems and methods

Abstract

The invention provides a defensive system and method of an unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicle countering. The defensive system of the unmanned aerial vehicle comprises a ground detection subsystem, a command and control subsystem and a disposition subsystem. The ground detection subsystem is used for detecting and tracking the target unmanned aerial vehicle and sending position information of the target unmanned aerial vehicle to the command and control subsystem; the command and control subsystem is used for receiving the position information and a capturing instruction input by a commander according to the position information and sending the capturing instruction to the disposition subsystem; the disposition subsystem comprises a capturing unmanned aerial vehicle, an unmanned aerial vehicle ground station and an RTK navigation system, and is used for receiving the position information and the capturing instruction, and the capturing unmanned aerial vehicle is guided to capture the target unmanned aerial vehicle through the RTK navigation system. With the defensive system and method of the unmanned aerial vehicle, high-precisionnavigation information can be obtained, the target unmanned aerial vehicle is convenient to capture, and the defensive efficiency of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of UAV countermeasures, in particular to designing a UAV defense system and method. Background technique [0002] With the widespread application of military and civilian drones in various fields, the control and countermeasures of drones have reached a situation that must be solved. In recent years, more and more drones have been used for intelligence reconnaissance, especially It is a "low, slow and small" UAV. Due to its low flying height, slow movement speed, and small radar scattering area, it is difficult for this type of UAV to detect and capture with a single detection method. At the same time, this kind of UAV The stealth design of man-machines also brings huge challenges to optical and radar detection. Moreover, its take-off and landing locations are random, the time available for detection and early warning is shortened, and it is relatively difficult to capture. [0003] Aiming at the above-ment...

[0002] With the widespread application of military and civilian drones in various fields, the control and countermeasures of drones have reached a situation that must be solved. In recent years, more and more drones have been used for intelligence reconnaissance, especially It is a "low, slow and small" UAV. Due to its low flying height, slow movement speed, and small radar scattering area, it is difficult for this type of UAV to detect and capture with a single detection method. At the same time, this kind of UAV The stealth design of man-machines also brings huge challenges to optical and radar detection, and its take-off and landing locations are random, the time available for detection and early warning is shortened, and it is relatively difficult to capture

[0003] For the above-mentioned technical problems that are difficult to capture by drones, no effective solutions have been proposed so far
