WebEvent matching is crucial to joint PP and PS AVA inversion. The PS wavelet will change with time when compressed to PP time because of the time-variant compression ratio. … The PM method (Carcione 2001, 2014) is used as the forward modeling engine for the inversion. Although it assumes a locally 1D subsurface model, it uses an exact solution to the full-wave equation. In seismology, a layered system can be a good representation of the stratified earth model. We consider the … See more Let {\mathbf{d}} be the observed-data vector, and \text{F} the synthetic-data vector for the unknown model {\mathbf{m}}. Here, \text{F}represents a nonlinear … See more A linear inversion scheme is used to reduce calculation costs. Based on an initial value, one can update the model results by several iterations. Gradient-based … See more The regularization parameter adaptive-acquisition methods can be classified into two categories: (1) priori selection methods that require knowledge of the … See more
