In this paper, the micro-Doppler model of simple harmonic micro-motion is constructed. The selection of the adaptive Pseudo Wigner-Ville Distribution (PWVD) window length for the micro-Doppler signal is investigated. Then, an estimation method of micro-Doppler parameter is proposed based on adaptive PWV-Hough transform. Simulation results are presented to demonstrate the effectiveness of the proposed algorithm.
