Radar Doppler has good application in both martial and civil aspect. The targetmoving parameters such as moving direction, moving velocity and so on can be wellestimated through the analysis of radar Doppler effect. A new academic system calledmicro Doppler which is put forward by the famous scholar Victor C.Chen is developingon the basis of micro motion model of the object.In this article, the micro Doppler effect of the vibration and rotation is firstlydiscussed which is depend on the specific micro motion such as vibration and rotation.And then the validity of the micro Doppler induced by vibration and rotation is testifiedwith the help of time frequency analysis. In the end, the method of micro Dopplerextracting is deeply discussed and meanwhile the analysis of the swing arms and thepositioning of cannonball in the space accounts for the advanced function of microDoppler in radar application aspect.
