| Abstract: | The receiver function method was originally developed to analyse earthquake data recorded by multicomponent (3C) sensors and consists in deconvolving the horizontal component by the vertical component. The deconvolution process removes travel path effects from the source to the base of the target as well as the earthquake source signature. In addition, it provides the possibility of separating the emergent P and PS waves based on adaptive subtraction between recorded components if plane waves of constant ray parameters are considered. The resulting receiver function signal is the local PS wave's impulse response generated at impedance contrasts below the 3C receiver.We propose to adapt this technique to the wide-angle multi-component reflection acquisition geometry. We focus on the simplest case of land data reflection acquisition. Our adapted version of the receiver function approach consists in a multi-step procedure that first removes the P wavefield recorded on the horizontal component and next removes the source signature. The separation step is performed in the domain while the source designature can be achieved in either the or the domain. Our technique does not require any a priori knowledge of the subsurface. The resulting receiver function is a pure PS-wave reflectivity response, which can be used for amplitude versus slowness or offset analysis. Stack of the receiver function leads to a high-quality S wave image. [ABSTRACT FROM AUTHOR] |
