Signal-to-noise ratio analysis for time-reversal based imaging techniques in bounded domains
We consider the problem of localizing small material defects in rectangular bounded
domains. The scalar acoustic equation is used to model wave propagation in this context …

[HTML][HTML] Computational vibro-acoustic time reversal for source and novelty localization
Time reversal has been demonstrated to be effective for source and novelty detection and
localization. We extend here previous work in the case of a coupled structural-acoustic …

A Numerical Study on Computational Time Reversal for Structural Health Monitoring
Structural health monitoring problems are studied numerically with the time reversal method
(TR). The dynamic output of the structure is applied, time reversed, as an external loading …
