Detection and location method for quickly searching for 5G signal interference source

A detection and location method for quickly searching for a 5G signal interference source is provided. A 5G signal interference source is comprehensively searched and located through the measurement and analysis of 5G signal configuration and 5G signal power by a spectrum analyzer carried by an unmanned aerial vehicle. The frequency of an interference source is locked in the spectrum interface, and whether the interference source is a 5G signal is verified through the synchronization identifier, physical cell ID, PBCH EVM and other indicators in the constellation interface; the direction of the 5G signal source is determined by measuring the SS-RSRP of the direction angle of each antenna; the unmanned aerial vehicle keeps tracking the direction with high interference signal power in the measurement process, hovers at a position where the interference signal gets stronger obviously to perform horizontal and vertical rotation coverage scanning, and observes a spectrum module and a remotely-controlled tablet com
