Abstract：Object discrimination based on resonant properties is one of the research topics in radar detection domain. Obvious transient resonances will take place for some kinds of underground Perfectly Electrical Conductors (PEC) targets under impulse electromagnetic field illumination. In this paper, numerical simulation of such resonances has been done by three-Dimensional Finite-Difference Time-Domain(3D-FDTD) method. The calculated results are verified by impulse Ground Penetrating Radar(GPR) measurements and good agreements are obtained. The properties of the resonant signals from buried PEC targets are analyzed through Singularity Expansion Method(SEM). The possibility for identifying buried target by its poles are studied. It is shown that one can apply resonant properties to identify buried targets under some condition.
