Problems solved by technology
At the same time, these aircraft have the characteristics of low flying altitude, slow speed, small radar reflection area (so-called "low, slow and small" aircraft targets), and are difficult to find on the ground, which makes it difficult for relevant departments to control drones, especially for key targets, Threats from key areas and major events are also becoming more prominent

Embodiment Construction
[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the invention.
[0026] The present invention provides a method for tracing the source of the UAV operator, such as figure 1 As shown, the method for tracing the source of the drone operator comprises the following steps:
[0027] S1. Collect target data detected by radar and target data detected by spectrum.
[0028] The radar detection target data is obtained by detecting the UAV through the radar detection device, and the radar detection target is Pr(Dr, Or, Tr), where Dr is the distance between the installation position of the radar detection device and the radar detection target, and Or is the r...

The invention discloses a method and a system for tracing an unmanned aerial vehicle operator. The method comprises the steps of acquiring target data of radar detection and target data of frequency spectrum detection; calculating first found position information of each frequency spectrum detection target, and constructing frequency spectrum tracing information; then, sequentially comparing absolute values of difference values between an azimuth angle of a single non-associated radar detection target and the azimuth angles of all non-associated frequency spectrum detection targets at the samemoment, with a preset frequency spectrum correlation threshold, and judging whether the radar detection target is associated with the frequency spectrum detection targets or not according to comparison results; and finally calculating radar tracing information of the radar detection target associated with the frequency spectrum detection target at the moment when the frequency spectrum detectiontarget is found for the first time. An intersection of the tracing information of the frequency spectrum detection target and the tracing information of the radar detection target is tracing information of the unmanned aerial vehicle operator, so that the position of the unmanned aerial vehicle operator can be quickly positioned; and a technical means is provided for a law executor to quickly control the unmanned aerial vehicle operator.
Description
technical field [0001] The invention relates to the field of anti-drone technology, and in particular to a method and system for tracing the source of a UAV operator. Background technique [0002] In recent years, the application of various civilian consumer drones has exploded, bringing convenience to production and life. At the same time, these aircraft have the characteristics of low flying altitude, slow speed, small radar reflection area (so-called "low, slow and small" aircraft targets), and are difficult to find on the ground, which makes it difficult for relevant departments to control drones, especially for key targets, Threats from key areas and major events are also becoming more prominent. How to control illegal drones has become a hot issue, and if traceability information can be obtained through technical means, and the operator can be caught, it will have a huge shocking effect on the "black flyers". The traceability information here refers to the location o...
