摘要：

针对雷达辐射源指纹特征提取困难的问题,提出了基于双谱切片法和双谱围线积分法,提取辐射源指纹特征的方法。介绍了二相编码信号的无意调制,仿真了理想情况和含有相位噪声的二相编码信号的时域波形。阐述了含相位噪声雷达信号的双谱估计,仿真了含相位噪声的二相编码信号的双谱图及等高图。最后利用双谱切片法和双谱围线积分法,提取了辐射源的指纹特征,通过计算机仿真实验验证了该方法的可实施性。

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
