The feature of micro-motion is one of the most effective features used for radar recognition in midcourse phase. At present, the study of feature extraction and recognition is usually based on the assumption that the micro-motion of the scattering center and warhead itself is the same, and the radar echo is sinusoid-FM signal. However, this assumption ignores the fact that the scattering center would slide on the warhead with the change of the aspect angle. In this paper, a complete micro… CONTINUE READING
