A three-dimensional finite-difference time-domain method that employs pure scattered-field formulation and perfectly matched layers (PML) as the absorbing boundary condition is developed for solving subsurface-scattering. A subsurface radar is modeled and the fields scattered from various buried objects with different parameters such as the size, depth, and number are observed and distinguished. The `derivative' signal, which can easily be obtained in practical systems, is useful in identifying the buried objects.
