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。
Median filtering can highlight wave band better than 2-d velocity filtering does. It also causes a better VSP wave field separation.
为此，采用T-X域时差变换滤波技术，即在T-X域内将曲线型相干噪声线性化，通过视速度差异去除噪声，从而达到压噪目的。
Therefore, moveout transform filtering method in T-X domain was adopted, which linearized the curved coherent noise in T-X domain, and remove noise by the contrast of apparent velocity.
