| 摘 要： | 偏振滤波是三分量VSP纵、横波波场分离最常用的方法之一。在传统的偏振滤波方法中，偏振角的计算是基于直达波的传播方向而确定，没有针对所需要的上行波。本文通过建立针对反射波的主能量方向计算偏振角，建立随反射深度变化的坐标系，即浮动坐标系，以有效提高波场分离精度。理论模型试算和实际资料处理结果表明，在浮动坐标系下，偏振滤波方法以所需波场为基础，能够实现波场的最优分离。

| Abstract: | Polarization filtering is one of the most commonly used filtering methods for 3 component VSP PP-PS wave field separation.For traditional polarization filtering methods,calculation of the polarization angle is determined by the propagation direction of the direct wave,not the necessary upgoing wave.In this paper the polarization angle is calculated along the major energy direction of the reflection wave,and the coordinate system which varies with reflection depth,this is,the floating coordinate system,is th... |
