Abstract：In order to improve the recognition accuracy of the radar radiation source identification method,the carrier frequen-cy characteristics of the pulse signal are proposed to identify the radiation source.For the measured pulse signal data,the time-fre-quency domain conversion is realized through FFT,and 15 kinds of frequency domain statistical features are extracted,and then 10 kinds of fingerprint features that can best represent the difference between individuals are screened by PCA algorithm.Finally,the extracted features are used as input to realize individual recognition through three kinds of independently constructed classifiers.The experimental results show that the frequency domain features can be applied to the classification and identification of radiation sources.
