Abstract

Abstract:

In order to extract the micro-Doppler of multi-scatters when the echo is subject to strong noise and translation modification, a method based on the instantaneous Doppler of the strongest scatter is proposed. The instantaneous Doppler of the strongest scatter is obtained by the Viterbi algorithm. The translation Doppler is extracted according to the relation between Doppler rate and micro-Doppler. Translation parameters, on the basis of which the translation signal is reconstructed, are estimated by polynomial regression. Then translation modification is compensated and Micro-Doppler parameters of every scatter are extracted by Hough transform. Simulation results indicate that the method is valid and accurate.

Key words: ballistic target, micro-motion, micro-Doppler, Viterbi algorithm, Doppler rate, Hough transform
