Median filtering can highlight wave band better than 2-d velocityfiltering 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 velocityfiltering 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 velocityfiltering, differential, and then filtering.
