velocity filtering

基本解釋

Median filtering can highlight wave band better than 2-D velocity filtering does. It also causes a better VSP wave field separation.
中值濾波較通常的二維視速度濾波更能有效地突出波組特征，分離VSP波場的效果也較二維濾波優(yōu)越。
Hyperbolic velocity filtering and similar coefficient method are introduced to remove the influences resulting from end-point effect and alias.
為了消除端點和假頻影響，文中采用了雙曲線速度濾波法和相似系數(shù)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.
采用對車速信號進行濾波、差分、再濾波的方法獲得了具有良好實時性和精度的汽車縱向加速度。
