1. A method for using a selected guided wave having a characteristic to determine a location of a real flaw in an inspected object having a geometry and a multiplicity of theoretical flaw locations, comprising the steps of: selecting a time-varying dispersion-modeled reference signal associated with the geometry of the inspected object, the multiplicity of theoretical flaw locations within the inspected object, and the characteristic of the guided wave; launching the selected guided wave into the inspected object; receiving a reflected signal generated by the interaction of the selected guided wave and the geometry of the inspected object including any real flaw located therein; comparing the selected time-varying dispersion-modeled reference signal with the received reflected signal; and determining the location of the real flaw in the inspected object if the time-varying dispersion-modeled reference signal is substantially similar to the received reflected signal.
