Abstract :
A three-dimensional, full-wave ground-penetrating radar simulator is presented. The finite-difference time-domain technique is used to calculate the fields scattered by objects buried in a stratified lossy half-space. A novel near-to-far field transformation and a method to predict scattered fields resulting from incident plane waves is presented
