Extraction of JEM Signature Based on Decomposing the Return’s Amplitude and Phase

ZHU Zhang-fan1,DING Jian-jiang2(1.Department of Graduate Management,AFRA,Wuhan 430019,China;2.Division of Scientific Research,AFRA,Wuhan 430019,China)  
Based on comprehending and analyzing the amplitude and phase of aircraft returns from the routine air-defense radar,a method of extracting JEM signature based on decomposing the returns into amplitude and phase was proposed,namely to extract the JEM signature singly by both AR spectrum estimation for phase and wavelet transform for amplitude.The analysis of factual sampling data shows that the extracted JEM signature is steady,and by signatures synthesis the value of signature estimation is precise and its error is reduced.The method can be used to recognize the aircraft targets that produce JEM signature.
