Simulation of the effect of system and geometrical parameter variations on wave scattering from buried objects using FDTD

Detection of buried objects has continually been of great concern especially because of the damaging effects of landmines.; ISAR imaging techniques are explored for simulation of wave scattering from 3-D buried objects using FDTD. Available computer algorithms are used to simulate for various burial depths, soil moisture content and varying object dimensions.; Far field data is collected at the laboratory while the buried object is rotated in the azimuth angle to synthesize an ISAR aperture.; The images obtained using computer simulations and laboratory experiments are presented and discussed.
