| Summary: | 博士 === 國立中央大學 === 地球物理學系 === 84 === The purpose of this study is to find a new technique to image
the p-q slowness surfaces directly from walk-away VSP by a full
wave field transformation in layered models. This method, is
based mainly on performing the linear Radon transform twice.
The first linear Radon transform acts as a τ- p transform, and
This method can be applied to any component of 3D/3C WVSP to
estimate the corresponding p-q slowness surfaces and to
correlate each surface. We conducted both numerical and p
velocity polar function for azimuthally anisotropic media.
Moreover, through the SH component analysis, the features of S
wave splitting can be seen in the p-q slowness surface.
