Conclusions
A time-domain tool to simulate GPR problems has been developed and tested. It uses an automatic geometry preprocessor based on AutoCAD to define the full problem in a versatile way. The kernel of the tool is a non-uniform FDTD simulator which can handle inhomogeneous dispersive media terminated by PML conditions, as well as wire structures, through the incorporation of the MoM solution of the wire problem, coupled to the FDTD zone via the equivalence principle. We have used this tool to study the transient excitation of inhomogeneous bodies by thin-wire broadband antennas and specifically to simulate a short-pulse GPR.
