Reference free inconsistency detection system

摘要

A method and apparatus for identifying an inconsistency. A number of waves that propagate through a structure are generated. A response signal is generated in response to detecting at least a portion of the number of waves that propagate through the structure. A determination is made as to whether the response signal includes a reflected component. A presence of the inconsistency in the structure is indicated when the response signal includes the reflected component.

1. A method for identifying an inconsistency, the method comprising:
generating a number of waves that propagate through a structure; generating a response signal in response to detecting at least a portion of the number of waves that propagate through the structure; determining whether the response signal includes a reflected component; indicating a presence of the inconsistency in the structure when the response signal includes the reflected component; and identifying information about the inconsistency by identifying an m value, wherein the m value is half of a product of a central frequency for the number of waves and a difference in arrival time of a transmitted portion and a reflected portion of the at least a portion of the number of waves detected.
