| Abstract: | The conception of micro-Doppler rate was introduced.MicroDoppler was investigated for typical targets of micro-motion.Then time-frequency analysis was used to extract micro-Doppler signature,based on which an approach was proposed for estimating motion parameters.A simulation of micro-Doppler was presented for typical targets of micro-motion.The result of emulation validates the theoretical analysis. |

| Keywords: | signature extraction micro-motion micro-Doppler time-frequency distribution |
