超声多普勒血流信号的时间－频率表示法

Time-frequency representation for Doppler ultrasound flow signals

介绍了维纳分布和复合型核时间－频率分布两种信号的时间－频率表示法，然后将这两种表示法应用于超声多普勒血流信号分析实验，并对结果进行了讨论．

Two methods of time-frequency reprsentation for signal analysis are introduced in this paper. The properties of these methods are analysed, and their applications to Doppler ultrasound boold flow signal analysis experiments are presented.
