Three-dimensional (3D) seismic surveys are always more often used both in oil prospection and in near surface problems to handle complex geological structures. At the same time surface wave methods are often coupled to other seismic techniques (2D seismic reflection or refraction) where we can use seismic data to retrieve dispersion curve along the seismic line. In this work we prove the possibility of retrieving dispersion curves from cross-spread 3D seismic acquisition scheme. Several tests based on synthetic and real data show that the dispersion curves estimated from cross-spread seismic acquisition scheme are in agreement with the dispersion curves estimated through the traditional methods. Furthermore, through a 3D synthetic model, we show that the proposed processing approach can be used to retrieve 3D subsoil models, also for inaccessible areas.
