Estimation of micro-motion parameters based on micro-Doppler

Micro-Doppler has played an important role in describing the micro-motion of a radar target. After analysing the characteristics of micro-Doppler induced by typical micro-motions, a technique based on time-frequency transform and Hough transform is introduced, to extract the modes and estimate the parameters of multiple frequency modulation components in micro-Doppler simultaneously, which can describe the properties of radial micro-motion. Experiments show the performance of estimation algorithm with simulating radar data.
