Micro-Doppler Feature Extraction Method for Target with Rotating Parts
摘要
Abstract
Rotation and vibration are the most familiar moving forms in micro-motion dynamics. Micro-Motion targets will generate Micro-Doppler phenomenon; the Micro-Doppler feature can be recognized as the unique feature of Micro-Motion targets; which can be used for identifying the characteristics of target; and implementing auto target recognition and classification. Under the chirp signal system; after motion compensation; targets with rotating parts will show the special form in spectrogram. In terms of the different radius; the different methods are utilized; which can achieve the separation and extraction of Micro-Doppler; the feature identification and classification of special targets will be implemented. At last; the effectiveness of the methods is testified by the simulation results.关键词
