Abstract

Abstract The jet engine modulation (JEM) effect is given. The backscattered characteristic of the electro-magnetic wave of airplane is analyzed. The spectral analysis technique based on cumulant is used to process the practical dynamic data by low-resolution radar, and the JEM spectral line is obtained. The implication for JEM target identification system is discussed based on the fuzzy neural network (FNN) and the short time Fourier transformation (STFT).
