| 摘 要： | 当地震波非垂直入射并在地下存在波阻抗差时,就会产生转换波。由于转换波和入射波之间存在差异,所以可以利用其差异对其进行分离识别。主要介绍了几种PSV波的分离识别方法,并用极化滤波法对波场进行分离识别。

| Abstract: | When the seismic wave is't vertical incidence and there is wave-impedance difference under the ground,it will form converted wave.Because it exists difference between the converted wave and incidence wave,we can identify and separate them through the difference.This text mainly introduces several ways of identifying and separating the psv wave,and then uses the polarization filtering to identify and separate it from the wave field. |

| Keywords: | multi-wave survey wave field separation converted wave polarization filtering |
