Dual-mode radar signal sorting method based on adaptive density peak clustering

The invention discloses a dual-mode radar signal sorting method based on adaptive density peak clustering, and the method comprises the following steps: S1, data initialization: employing carrier frequency, pulse width and arrival angle three-dimensional information of a radar signal as feature vectors, carrying out the normalization processing, and segmenting the feature vectors into a series of equal-length time frames according to the duration; s2, establishing an adaptive density peak clustering sorting mode; s3, establishing a Gaussian mixture model clustering sorting mode; s4, establishing a dual-mode switching strategy: the first frame of data adopts an ADPC mode, and the second frame of data adopts a GMM mode; for the data of the third frame and subsequent frames, which sorting mode is used by the input data of the time frame is determined based on a mode selection strategy. According to the dual-mode sorting method, the radiation source parameter slow change and sudden change existing in the electrom
