Unmanned aerial vehicle tracking and intercepting system and method aiming at low and slow small targets

Abstract

The invention relates to an unmanned aerial vehicle tracking and intercepting system and method aiming at low and slow small targets. The system comprises a ground detection tracking device, a ground control station, a differential GPS reference station and an unmanned aerial vehicle platform; the ground detection tracking device is used for searching and finding a low and slow small target in the air, accurately tracking the found and detected low and slow small target and giving target indication information in real time; the ground control station is used for receiving target indication information of the ground detection tracking device in real time; the differential GPS reference station adopts three-dimensional coordinates to perform error correction on the GPS positioning information of the unmanned aerial vehicle platform in real time, and then sends the correction amount to the unmanned aerial vehicle platform in real time; and the unmanned aerial vehicle platform is used for receiving target indication information of the ground control station and the corrected GPS positioning information to perform remote control autonomous flight, and simultaneously carries the task load module to execute tracking and intercepting tasks. The unmanned aerial vehicle tracking and intercepting system and method aiming at low and slow small targets achieves the accurate tracking and interception of the low-speed small target.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle tracking and interception system and method for "low, slow and small" targets. Background technique [0002] "Low, slow and small" targets are easy to be used by criminals and hostile forces because of their low cost, simple control, and low threshold for use. They can be remotely controlled or preset flight paths. In recent years, there have been a number of incidents at home and abroad such as illegal aerial photography, disrupting civil aviation flight order, threatening large-scale activities, etc., posing great harm to public safety. [0003] The difficulty in the prevention and control of "low, slow and small" targets is that the penetration time is short, and it is easily affected by tall buildings, trees, lights, vehicles, birds, and various civilian frequency bands, making it difficult to find and track, and the efficiency of d...
