Embodiment 1

[0044] Such as figure 1 As shown, a highly maneuverable active capture anti-UAV system, including:

[0045] The unmanned aerial vehicle system consists of a tilting fuselage unmanned aerial vehicle 1, a capture frame 2, a camera or infrared sensor 3, a flight control and electromagnetic interference system, and various sensor devices 4, a catch net 5 and a second optical radar 7, in:

[0046] The capture frame 2 is installed between a pair of fixed wings of the tilting body type UAV 1, and is located above the tilting body type UAV 1; the capture frame 2 is fixed on The tilting fuselage type UAV 1 will not damage the aerodynamic shape of the fuselage;

[0047] The camera or infrared sensor 3 is installed at the center of the tilting body type UAV 1 for terminal guidance: when the target aircraft 8 enters the terminal guidance area of ​​the tilting body type UAV 1 (i.e. the camera Or the infrared sensor 3 can clearly detect the area of ​​the target aircraft 8), the tilting f...

Embodiment 2

[0064] A highly maneuverable active capture anti-drone system, which differs from Embodiment 1 in that image sensors or ultrasonic sensors are used for terminal guidance.

[0065] The image sensor or ultrasonic sensor is installed on the top of the tilting body type UAV 1, and the image sensor or ultrasonic sensor is used for the terminal guidance of the tilting body type UAV 1, and detects the position of the target aircraft 8 and pursues it ;in:

[0066] The image sensor is used to collect the image of the target aircraft 8 and package the collected image data, specifically including image preprocessing, feature extraction, and similarity measurement with the feature parameters of the template image to complete the recognition task, and simultaneously calculate Get the coordinates and angles of the target aircraft 8 in the image coordinate system, then transfer the image data to the flight control system, and the flight control system processes and processes the information ...

Embodiment 3

[0070] Based on the system described in the above-mentioned embodiments 1 and 2, a highly maneuverable active capture anti-drone method includes:

[0071] First, the ground station system monitors the set area in an all-round way through the first optical radar. Once the target aircraft is found to enter the set area, it sends the position information of the target aircraft to the anti-UAV system; the anti-UAV system receives After the location information of the target aircraft is chased and captured, the ground station system is used to transmit signals during the pursuit and capture process of the UAV, and controls the UAV to locate and chase the target aircraft;

[0072] In the final stage of approaching the target aircraft, the UAV adopts a composite guidance method, specifically:

[0073] When the drone is chasing the target aircraft head-on, it detects the precise position of the target aircraft through the terminal guidance device, and transmits an electromagnetic inte...

Abstract

The invention provides a high-mobility active capture type anti-unmanned aerial vehicle system and method. The system comprises an unmanned aerial vehicle, a capture frame, a terminal guidance device, a flight control and electromagnetic interference system, a sensor device and a capture net, wherein the capture frame is mounted above the unmanned aerial vehicle; the capture net is mounted in the capture frame to achieve a buffering effect when low, small and slow targets and other aerial small flying targets (such as birds) are captured; and the terminal guidance device, the flight control and electromagnetic interference system and the sensor device are mounted in the center position of the unmanned aerial vehicle. According to the invention, a ground station system is used for controlling a novel fuselage tilting type unmanned aerial vehicle with vertical takeoff and landing and high-speed cruise capabilities, and low, slow and small targets and other aerial small flying targets are captured in high precision and high mobility according to multiple guidance modes. The system captures the targets by adopting the novel fuselage tilting type unmanned aerial vehicle with high mobility according to multiple guidance modes, secondary capture can be carried out, and the cost is low.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a highly maneuverable active capture anti-unmanned aerial vehicle system and method. Background technique [0002] In recent years, various civilian consumer drones have been used more and more widely, bringing convenience to production and life. These aircraft fly at low altitudes, slow speeds, and have small radar reflection areas (so-called "low, slow and small" aircraft), making them difficult to detect and control on the ground, and pose serious threats to key targets, key areas, and major activities. How to control / reject illegal drones has become a hot issue. The preferred goal of countering "low, slow and small" is to effectively intercept it before it invades sensitive airspace. [0003] Searched: [0004] Chinese patent application: A fixed anti-drone interception network system" (201610062946.X), which consists of an interception network body, a traction netw...
