ABSTRACT

Ray-based numerical simulations of monostatic and bistatic
GPR responses for several tank and pipe configurations reveal the
potential for non-invasive diagnostic evaluations. Examples
include discrimination of the material from which a tank is
constructed, its size, contents, fluid levels, and shape changes.
Ambiguities occur when different configurations
give similar responses, and evaluations become less reliable 
as noise increases. Simulations are able to reproduce the salient
features of field GPR data recorded over a metal pipe, and over 
plastic pipes filled with air, fresh water, and salt water.
