By introduced the micro-Doppler, this paper mainly analyzed the parameter extraction method, which can extract the angular frequency, amplitude and phase of the micro-motion target.
利用单距离多普勒干涉法对旋转目标进行了成像，实现利用成像结果提取微动特征参数的目的；
Finally, imaging simulation of point target in the condition of antenna micro-motion is done. Imaging results before and after compensation are compared combined with imaging characteristic.
最后在天线微动条件下对点目标进行了成像仿真，并结合成像特征对天线微动补偿前后的结果进行了分析比较。
