Abstract
The study of the polarization directions and the travel-time delay between split shear-waves is particularly important in the interpretation of subsurface anisotropy from seismic experiments. Over recent years, several techniques have been put forward to analyse the shear-wave splitting to extract these characteristic parameters, MacBeth and Crampin (1991a) having reviewed most of these methods. Here, the analysis of vertically propagating shear-waves is placed in the context of a convolutional model which can be used to simulate the effects of anisotropy, in addition to the more commonly examined effects of reflection, transmission, dissipation, and propagative time-shifts, on the shear-waves .
