Abstract
A method, apparatus, and computer usable program code for identifying change indices for a structure. In one advantageous embodiment a method receives a response signal in response to a transmission of an interrogation signal into the structure. The response signal is decomposed into a first plurality of modes. The first plurality of modes is compared to a second plurality of modes for a comparison signal to form a comparison. A change index is assigned to the response signal using the comparison.
