Unmanned aerial vehicle interference countering system

Abstract

The invention discloses an unmanned aerial vehicle interference countering system and belongs to the field of unmanned aerial vehicle prevention and control strategies. The system comprises an interference module, a center control module and a direction-finding module, wherein the direction-finding module comprises N direction-finding stations; each direction-finding station comprises an antenna array, a direction-finding algorithm module, a GPS signal module and a first communication module; the interference module comprises an antenna array, a servo device, an interference signal generationmodule and a second communication module; and the center control module comprises a positioning module, a signal time-frequency characteristic analysis module, an interference decision module, a display module and a third communication module. The first communication module of each direction-finding station is connected with the third communication module of the center control module to realize signal transmission; and meanwhile, the third communication module of the center control module transmits a signal to the second communication module of the interference module. Through the countering means, complexity is low, difficulty is low, safety is high, and cost is low.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle prevention and control and control strategies, in particular to an unmanned aerial vehicle interference countermeasure system. Background technique [0002] With the rapid growth of UAV flight volume, the problem of UAV safety flight supervision has become increasingly prominent. In recent years, there have been a large number of UAV safety flight accidents at home and abroad. [0003] The FAA of the United States receives a large number of drone accident reports every year, and the number of reports shows a trend of substantial growth, highlighting the growing threat of drones to the safety of American civil aviation. In my country, there have also been many safety accidents in recent years, such as unmanned aerial vehicles breaking into flight restricted areas, dangerously approaching manned aircraft, and hitting ground vehicles. [0004] It can be seen that while drones bring convenience...
