中文摘要：
微动特征的提取对于目标识别具有重要意义，但现有算法提取多分量旋转目标微多普勒参数的计算量太大。针对这一问题，提出了一种Hough变换撤票策略，对时频空间进行Hough变换得到参数空间，对已包含所有信息的参数空间进行多次撤票，便可分步得到微多普勒信号参数。仿真实验验证了该方法的有效性。
英文摘要：
The information extraction from multiple spinning micro-Doppler （mD） scatters is of significance in target identification. Existing method to extract information which maps time-frequency plane to parameter space repeatedly is time consuming. The withdrawal vote strategy based on hough transform （HT） , which could reduce the calculation time span, is put forward. The numerical experiment is given.
