摘　　要：研究了对激光多普勒信号的处理方法,利用Labview和Matlab软件的强大信号处理功能,对采集的多普勒信号进行小波滤波,并经过时频分析,得到被测器件的运动参量(速度、位移、加速度)。与其它处理方法相比,该方法有效地提高了整个软件处理系统的分辨率和测量精度。A study on the method of laser Doppler signal processing is proposed. Software Labview and Matlab are used in signal processing to measure the movement parameters of a device such as velocity, displacement and acceleration. In the software, wavelet filtering and time-frequency analysis are used. Compared with other methods of the signal processing, the method used here improves the resolution and precision of the whole system effectively.
