Abstract:
Methods for detection, monitoring, and determination of location of changes in rigid structures with arbitrarily complex geometries are described. Implementations include locating acoustic transducers that generate and receive acoustic signals at multiple locations along a surface of the rigid structure, wherein longitudinal spacing between the transducer locations define measurement zones. Acoustic signals with chosen amplitude-time-frequency characteristics excite multiple vibration modes in the structure within each zone. Small mechanical changes in the inspection zones lead to scattering and attenuation of broadband acoustic signals, which are detectable as changes in received signal characteristics as part of a through-transmission technique. Additional use of short, narrowband pulse acoustic signals as part of a pulse-echo technique allows determination of the relative location of the mechanical change within each zone based on the differential delay profiles.

Claim (Index 13):
The method of  claim 1 , further comprising:\n dividing the first and second monitoring transmission signals into a selected number of equal-duration time bins as a function of time; calculating a cross-correlation function for the first and second monitoring transmission signals and the first and second baseline transmission signals within a time bin; determining a time shift for the time bins by locating a peak of the cross correlation function; assigning a value of the first and second monitoring transmission signals to a time bin corresponding to a value of the first or second baseline transmission signals at a corresponding time shifted time bin; and performing temperature compensation of the monitoring signal using the baseline signal as a comparison signal, thereby generating a temperature-compensated monitoring signal.
