The invention discloses a self-adaptive channelization detection method based on spectrum sensing, which belongs to the field of electronic reconnaissance and is used for carrying out spectrum sensing, spectrum analysis, channel matching, detection and parameter estimation on electromagnetic signals and outputting a detection result. The method comprises the following steps: firstly, sequentially carrying out AD sampling and short-time Fourier transform (STFT) on an electromagnetic signal of a monitoring frequency band to obtain spectrum sensing data; performing real-time energy spectrum density estimation on the frequency spectrum sensing data input to generate a mean value spectrum and a maximum value spectrum; performing spectrum analysis on the frequency band of the signal distribution through the mean value spectrum and the maximum value spectrum, and generating a channel adaptation parameter; and carrying out adaptive adjustment on the digital channelized structure according to the ...
