Embodiment 1

[0039] Such as figure 1 , 2 As shown, an unmanned aerial vehicle electromagnetic countermeasure device includes: an interference signal transmitting unit 1, an interference signal sorting unit 2, a feedback control unit 3, a controller unit and a power supply unit (not shown in the figure), the interference The signal transmitting unit 1 is arranged in the middle part of the inner side of the interference signal sorting unit 2, and the feedback control unit 3 is arranged at the outer bottom of the described interference signal sorting unit 2; the controller unit is integrated in the power supply unit, and is connected with the interference signal transmitting unit 1. Signal connection between the interference signal sorting unit 2 and the feedback control unit 3;

[0040]The interference signal sorting unit 2 includes a parabolic signal reflection surface 201, and reflectors 202 are symmetrically arranged on both sides of the paraboloid signal reflection surface; the paraboli...

Embodiment 2

[0052] Such as image 3 As shown, the signal coverage of an electromagnetic countermeasure device for a UAV is shown. The coverage is narrow in the horizontal direction and high in the vertical direction, forming a long and narrow area.

Embodiment 3

[0054] In order to make up for the lack of positioning accuracy of the UAV detection equipment for the black flying UAV A, it is necessary to make the interference signal emitted by the UAV electromagnetic countermeasure device of the present invention reach the black flying UAV A, at least in the horizontal direction However, the interference signal coverage in the horizontal direction is too wide and will have a great impact on the surrounding residents. Therefore, when the distance of Heifei UAV A is relatively close, it can be adjusted by rotating The screw shortens the overall length of the reflector to achieve short-range signal coverage in a wide horizontal range; when the distance of Heifei UAV A is far away, the overall length of the reflector can be lengthened by turning the adjustment screw to make the interference signal more Gather together to achieve long-distance signal coverage in a certain horizontal range.

Abstract

The invention relates to an unmanned aerial vehicle electromagnetic countering device which comprises an interference signal transmitting unit, an interference signal sorting unit, a feedback controlunit, a controller unit and a power supply unit, the interference signal transmitting unit is arranged in the middle of the inner side of the interference signal sorting unit, and the feedback controlunit is arranged at the bottom of the outer side of the interference signal sorting unit; the controller unit is integrated in the power supply unit and is in signal connection with the interferencesignal transmitting unit, the interference signal sorting unit and the feedback control unit; the interference signal sorting unit is a paraboloid-shaped signal reflecting surface, and reflecting plates are symmetrically arranged on the two sides of the paraboloid-shaped signal reflecting surface; the horizontal width of the coverage range of the directional interference signal is limited, a longand narrow interference signal coverage area is formed, and compared with a planar signal interference coverage area of a common unmanned aerial vehicle countering device, signal interference in the direction of the non-black-flight unmanned aerial vehicle is effectively reduced, and the influence on the life of nearby residents is greatly reduced.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle management and control, and in particular relates to an electromagnetic countermeasure device for an unmanned aerial vehicle. Background technique [0002] UAV, that is, unmanned aircraft, with the development of science and technology, UAV technology has been greatly developed. At present, my country's research in the field of UAV is in the leading position in the world. [0003] In addition to military use, UAVs are also widely used in civilian fields; Huge effect. [0004] With the development of drone technology, the number of drones continues to grow, which has aroused people's concerns about risks such as drone use safety accidents and social security, and has also attracted great attention from national regulators and all walks of life. Especially in densely populated urban areas. There are also some reports in the news from time to time that drones have harmed people, damaged publ...
