Abstract

In many papers there are approaches for solving subsurface sensing and identification of subsurface objects based on FDTD methods with original method of identification (Pockok et al., 1998, Rao et al., 2002). There are not efficient for complex objects and lengthy object (its geometrical size is larger than pulse longitude). In this paper a numerical model for calculating far field scattered by complex objects is described. An evaluation is based on analytical evaluations. The results for some testing objects are represented.
