Paper Abstract

Micro-Doppler effect and its mathematical model were discussed. The Micro-Doppler effect of vibration and rotation of moving point target were analyzed. The micro-Doppler frequency shift induced by vibration is simulated and proceeded by means of the time-frequency analysis. A micro-Doppler Solid-state coherent ladar system for detecting micro-motion of target was demonstrated to detect the micro-Doppler frequency shifts induced by vibration, complex micro motion and rotation, and the micro-Doppler frequency shift induced by rotations at 0.2 r/s or vibrations at 0.5Hz were detected. The information of micro-motion was extracted by the arithmetic of time-frequency analysis. These results are helpful for target's feature extraction and identification.
