基于围线积分双谱的雷达辐射源信号个体特征提取
摘要
Abstract
Radar emitter signals have their individual feature due to inevitable oscillator phase noise. Specific Emitter Identifi-cation(SEI)technology extracts subtle and persistent features from intercepted emitter signals. These features are fingerprint information created by specific radar. An approach based on surrounding-line integrated bispectrum is proposed to extract unin-tentional phase modulation features caused by oscillator. The quantitative features, i.e.bispectra entropy, mean and waveform entropy of surrounding-line integrated bispectrum, are further extracted from bispectrum to reveal the individual difference between emitters. Computer simulation results show that the quantitative features can classify emitters by using individual dif-ference under moderate SNR circumstance.关键词
