Compared with the conventional microwave radar,lidar micro-Doppler effect has a higher spatial resolution and sensitivity,it has high measurement precision and strong anti-interference ability in target detection and identification.This article analyzes micro-Doppler and Doppler effect generated by motion of the vibrating object.Typical target motion model is established.Through the spectrum and frequency shift,we can have a good observation about object motion state and vibration characteristics of the object.Finally,simulation proves that the theory is helpful in target recognition and movement characteristics analysis.
