Seismic full-waveform inversion (FWI) for imaging Earth's interior was introduced in the late
1970s. Its ultimate goal is to use all of the information in a seismogram to understand the …

By allowing spatial variations in the direction of the anisotropic fast axis, tilted transverse
isotropy (TTI) helps to image complex or steeply dipping structures. Without a priori geologic …

弹性波速度是弹性波动力学研究的核心内容之一. 倾斜横向各向同性(TTI) 介质弹性波相速度的
理论精确公式比较复杂. 由于地球介质弱各向异性的普遍性, 在理论研究和实际应用中常常采用 …

Transversely isotropic media with a tilted symmetry axis (TTI) exits widely underground due
to tectonic movement and mineral orientation. Traditional full waveform inversion (FWI) …

We present 3D anisotropic imaging results using transverse isotropy parameters together
with tilt angle and azimuth. The resulting parameterization can be used to provide full spatial …

Reaching the global minimum of a waveform misfit function requires careful choices about
the nonlinear optimization, preconditioning and regularization methods underlying an …
