Unmanned aerial vehicle image transmission signal and hotspot signal identification method, medium and computer equipment

The invention belongs to the technical field of unmanned aerial vehicle signal detection and identification, and discloses an unmanned aerial vehicle image transmission signal and hotspot signal identification method, a medium, and computer equipment. The method comprises the steps of signal input: down-sampling an intermediate frequency signal and then inputting the intermediate frequency signal into a model for calculation; signal delay correlation detection: performing delay correlation processing on the signal in a time domain, and advancing a pseudo code period of the signal; spectrum peak detection: carrying out spectrum peak search after delay correlation normalization on a signal time domain, and advancing a spectrum peak value larger than a detection obvious value according to setting that adaptive detection is obvious; existance of a spectrum peak in a non-zero correlation point: detecting whether a spectrum peak exists in a signal delay correlation spectrum at a non-zero point or not, wherein the d
