Problems solved by technology

At present, the commonly used UAV anti-location methods include radar, antenna array, etc. Among them, radar has the characteristics of high cost, large size, difficult installation and portability, and has high requirements for operators.
The antenna array device receives the reflected signal of the UAV with the help of different azimuth antennas to realize the positioning of the UAV in the air. However, the receiving areas of the antennas in different azimuths have overlapping ranges in the spatial range, and there is no overlap in the spatial range. , Coverage without gaps, there is a large waste of resources and there is a large error in the positioning of aerial drones

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, a positioning method for attacking drones in the air, including a spherical camera module 1 and a hemispherical compass module 2, is specifically implemented according to the following steps:

[0029] Step 1. Determine the orientation of the drone;

[0030] Step 2, determine the distance of the drone;

[0031] Step 3. Implement countermeasures.

[0032] The spherical camera module 1 is installed at the center of the hemispherical compass module 2 and is fixed by a circular transparent glass with a radius of R. The spherical camera module 1 and the hemispherical compass module 2 are respectively connected to the control terminal. The spherical camera can rotate at a certain speed at the center of the sphere, and can capture all the scale areas on the inner wall of the hemispherical compass module; the hemis...

Abstract

The invention discloses a positioning method for hitting an unmanned aerial vehicle in the air, which comprises a spherical camera module and a hemispherical compass module, and is specifically implemented according to the following steps: 1, determining the orientation of the unmanned aerial vehicle; 2, determining the distance of the unmanned aerial vehicle; and 3, implementing countering measures. The positioning method is simple and ingenious in structure and convenient to manufacture, can be mounted and dismounted by only one person in use, saves manpower and material resources, can wellintegrate the two modules, achieves coordination work of the two modules, and has the advantages of being low in manufacturing cost, small in size, easy to mount, high in precision and the like. By using the positioning method, the position of the unmanned aerial vehicle can be accurately judged on the ground in real time, so that a ground target can judge the position of the unmanned aerial vehicle in time, unmanned aerial vehicle countering measures are implemented in advance, and the safety of ground facilities is ensured.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle positioning, and relates to a positioning method for aerial combat unmanned aerial vehicles. Background technique [0002] With the development of science and technology and the needs of information warfare, the technology of war UAV (hereinafter referred to as UAV) is more and more widely used in modern warfare. Forcing countries to urgently develop methods for UAV anti-location. [0003] When the strike drone strikes the ground target, it first needs to locate the ground target, and the ground target can only be struck after the position of the ground target is determined. At present, commonly used UAV anti-location methods include radar, antenna array, etc. Among them, radar has the characteristics of high cost, large size, difficult installation and portability, and has high requirements for operators. The antenna array device receives the reflected signal of the UAV with the...
