摘　　要：简单介绍了精确分析目标信息特征的必要性,通过对比小波变换和短时傅立叶变换,说明了小波变换用于分析引信多普勒信号的优势所在,具体论述以Daubech ies小波作为基函数,用于引信多普勒信号分析的原因和方法,并在文章的结尾通过仿真给出了直观对比。This paper simply introduces the necessity of precise analyses on information feature of object. It gives the predominance of fuze Doppler signal＇s analyses based on wavelet transform in comparison with short time fourier transform, discusses the reasons and methods of fuze Doppler signal＇s analyses using Daubechies wavelet as mother wavelet at length and shows the conclusion by simulated diagrams.
