摘　　要：阐述雷达多普勒效应和微多普勒效应的区别,在研究的微多普勒特征提取过程中主要是针对瞬时特征进行提取。将小波变换应用于合成孔径雷达的微多普勒特征提取。研究了Mallet算法特征提取的流程,并根据其流程进行小波分解与重构的仿真实验,通过实验来验证本文所采用的算法的可行性。This paper described the differences between radar and Doppler effect micro- Doppler effect. In the study of micro- Doppler feature extraction process was mainly for transient feature extraction.In this paper,wavelet transform was applied to synthetic aperture radar micro- Doppler feature extraction.Study feature extraction processes by the Mallet algorithm. And according to the process,the simulation experiment of wavelet decomposition and reconstruction was carried out. Experiments was used to verify the feasibility of the proposed algorithm.
