Abstract

Most standard procedures for dispersion analysis make use of multichannel wavefield transforms and the lateral velocity variations can be averaged spatially. On the other hand, the use of a local phase offset analysis can provide a very high lateral resolution. A new statistical enhanced multioffset phase analysis of surface wave data is presented. The phase processing of point receiver land data allows identification of velocity variations with a lateral resolution equal to the receiver spacing. An automatic procedure is set up to identify sharp lateral variation, and is tested on real land point receiver data. © 2010, European Association of Geoscientists and Engineers.
