Abstract:

In light of the difficulty in specific emitter fingerprint feature extraction,this paper presents methods for extracting fingerprint features based on bispectrum slice and bispectrum contour line integration.Firstly,this paper introduces non-intention modulation of BPSK signal,the time domain waveform of BPSK signal in the ideal case and containing the phase noise.Then bispectrum estimation of radar signal containing phase noise is elaborated.Bispectrum graph and contour graph of BPSK signal containing phase noise is simulated by the computer.Finally,we use bispectrum slicing method and bispectrum contour line integral method to extract specific emitter fingerprint feature,and validate the implement by the computer simulation.

Key words: fingerprint feature extraction;bispectrum theory;BPSK signal;bispectrum slices;contour line integration method
