  • Micro-dynamics characteristics are related to targets structures and can be used for target classification. Rotation structure of target is modeled as a sum of directional point scatterers. With the directional point scatter model, the micro-Doppler effect induced by rotation structure is analyzed. Then the joint time-frequency characteristics of radar echoes from targets which include rotation structure are investigated, and verified by real radar data. Finally, an extraction method of micro-motion characteristics, such as rotation frequency, is presented, and it is attempted to extract micro-dynamics characteristics, and the results are satisfactory.
