摘要
文中讨论小波变换应用于激光多普勒信号处理的方法。研究表明 ,通过连续小波变换 ,可检测多谱勒闪烁信号频移 ,在尺度域上突出测量体积中多粒子多普勒闪烁叠加信号的特征 。
The paper discusses the wavelet transformation applied to Doppler burst signal processing.It shows that the wavelet transformation can detect the Doppler frequency shift,emphasize the superposition bursts in scale domain.Therefore we can acquire good performance for identifying multi particles in measuring volumn.
