Detection of buried dielectric cavities using the finite-difference time-domain method in conjunction with signal processing techniques.

Detection of buried dielectric cavities using the finite-difference time-domain method in conjunction with signal processing techniques.

We address the problem of detecting low-dielectric contrast cavities buried deep in a lossy ground by using the finite-difference time-domain (FDTD) method in conjunction with signal processing techniques for extrapolation and object identification. It is well known that very low frequency probing i...
