Abstract :
Summary form only given. The scattering problem of a 2-D target has been considered by several researchers. In this paper the resonant characteristics for the scattering field are studied. The EFIE formulation is used. The equation for the total electric field is solved by using the MoM (Galerkin) we can find the equivalent current density and from this the scattering field. In both, frequency and time domain the most interesting thing is the appearance of characteristic resonances. The resonances depend on the depth, the size and the electromagnetic characteristics of the target and the underground environment. It is obvious that such characteristic properties could help one to recognize the geometry as well as the type of the underground targets
