Abstract：A method for micro-motion parameter estimation of radar target based on high-order moment function is presented,which is suitable for the narrowband radar.Firstly,the radar echo is mixed with the reference signal,and then its direct current is eliminated.The high-order moment function of the signal with different time delays is calculated firstly,then the Fourier transform results of the high-order moment's imaginary parts are calculated and the peak value of their product results is detected to obtain the rotation frequency of target's micro-motional parts.The radius and the initial phase are estimated by successive cancellation.A computer simulation is given to illustrate the effectiveness of the proposed method.
