N2 - We present a new technique that incorporates the radial and vertical components of an extended version of the Spatial Autocorrelation (SPAC) method (Aki, 1957), to improve surface wave dispersion estimates. Existing methods to retrieve vital near-surface properties generally use only the vertical components. We demonstrate the advantages of the multi-component SPAC, MuSPAC, by applying our method to numerical elastic wave simulations for a known source and earth model. We then add complexity to this model, and show that by summing sources over multiple offsets, that we successfully retrieve the velocity structure of the earth model.
