In this paper, we demonstrate the application of surface wave tomography to detect shallow-buried objects. To solve the problem of tomography, we developed a software package that implements the Ditmar-Yanovskaya method, which was created at St. Petersburg State University and has been successfully used in the field of seismology. We examined the developed software on several synthetic examples via the chess test and the real field data acquired on the shore of Gulf of Finland in Sestroretsk, St.Petersburg. During the field experiment, we established the location of the supposed buried long-term firing point (small bunker or â€œDOTâ€� in Russian) of the times of Finnish war and WWII as the presence of high velocity anomaly. This location is in the very good agreement of the result of magnetic survey. Also we established the location of the former riverbed as the low-velocity area. The results of this work suggest that developed software of surface wave tomography can be effectively used to study the near-surface and to detect the high- and low-velocity buried anomalies.
