TRANSIENT EM FIELDS SCATTERING BY UNDERGROUND OBJECTS
地下目标的瞬态电磁散射

Transient EM field scattering by underground objects using finite-difference method in time-domain (FDTD) is calculated, and object's response of an EM pulse related to dielectric parameters and underground structure is presented. Conclusions of this method can be used as theoretical evidences of object detecting and discriminating. The method can be applied to circumstances of arbitrary cylinder objects and two-dimensional underground structure, and can be developed to three-dimensional circumstances.
