Abstract

The invention discloses a radio frequency spectrum monitoring and positioning system and method based on a lift-off unmanned aerial vehicle. And a hybrid weighted positioning algorithm of a direction-finding cross positioning algorithm and an RSSI positioning algorithm is adopted to position the interference source. The influence of the environment, the channel noise interference and the antenna direction finding error angle on the positioning precision is reduced in a mode of mixing and weighting the positioning results of the two positioning algorithms; the positioning precision is high whenthe radio interference source in the low-altitude environment is positioned, the use is convenient, the problems that the positioning precision is low and the use convenience is poor when the radio interference source in the low-altitude environment is positioned are well solved, and the positioning method can be used for guaranteeing the safety application of civil aviation.

Description

technical field [0001] The invention relates to the technical field of outdoor radio spectrum monitoring and positioning, in particular to a radio spectrum monitoring and positioning system and method based on an aerial unmanned aerial vehicle. Background technique [0002] With the rapid development of the civil aviation industry, the increasing number of flights brings convenience to customers, but also poses a huge challenge to the safety of civil aviation. At present, there are two ways to threaten the safety of civil aviation: on the one hand, radio interference from the ground, such as radio stations without government permission and legal radio stations with intermodulation interference caused by irregular settings; on the other hand, there is a lack of targeted Effective prevention and control methods for low-altitude targets such as "Black Fly" UAVs, such as "Global Hawk" and "Heron", etc. UAVs continue to conduct border inspections of our country, posing a great th...
