N2 - Detecting and mapping small scale localized near surface inhomogeneities is an important problem in a variety of fields such as engineering, site investigation, environmental studies and archaeology. Most of the methods for imaging such local inhomogeneities are based on the use of travel-time surfaces for point-diffracted waves. In this study we consider the difference between a wave diffracted from an edge and a wave scattered from a cylinder-type object. We present an imaging technique which can be regarded as a generalization of the linear diffractor imaging method. We show that the new cylindrical approximation in some cases describes more accurately than the linear diffractor approximation, the kinematic characteristics of waves scattered on cylindrical objects with different radii.
