velocity filtering

基本解释

Median filtering can highlight wave band better than 2-D velocity filtering does. It also causes a better VSP wave field separation.
中值滤波较通常的二维视速度滤波更能有效地突出波组特征，分离VSP波场的效果也较二维滤波优越。
Hyperbolic velocity filtering and similar coefficient method are introduced to remove the influences resulting from end-point effect and alias.
为了消除端点和假频影响，文中采用了双曲线速度滤波法和相似系数法。
To investigate the method to obtain the real-time longitudinal acceleration based on its velocity, vehicle acceleration is obtained through the velocity filtering, differential, and then filtering.
采用对车速信号进行滤波、差分、再滤波的方法获得了具有良好实时性和精度的汽车纵向加速度。
