Abstract

Micro-Doppler based target recognition and classification methods are new approach of great significance. Translation will induce translation, slope and fold of micro-Doppler which will make it difficult to extract micro-Doppler, i.e., number of parameters in Hough method will be added. To solve the problem, we derived the motion, signal as well as Doppler model of rotating scatter. A micro-Doppler extraction method based on the relation of micro-Doppler and Doppler rate is proposed. Micro-Doppler extracted under 2-order polynomial and complicated translation, respectively, indicates that this method is effect.
