Iterative time reversal based flaw identification
In the field of ultrasonic non-destructive testing, ultrasonic impulses are used to detect flaws in componentswithout causing damage. Based onperforming experiments alone, it is possible to infer the state of the component – but this usually provides only limited details about the interior damage such as its position, dimension or orientation. Furthermore, the amount of sensors that can be used...
متن کاملIterative time reversal in the ocean
The iterative time-reversal process focusing on the strongest scatterer in a multitarget medium has been described theoretically in terms of eigenvalues and eigenvectors of a time-reversal operator K*K in ultrasonics @Prada et al., J. Acoust. Soc. Am. 97, 62–71 ~1995!#. In this paper, we extend the concept of iterative time-reversal to waveguide propagation in the ocean. For a single target, th...
متن کاملIterative time reversal with tunable convergence
Introduction: Spatiotemporal focusing of waves has applications in fields such as imaging and communication. Time reversal (TR) mirrors have been used to focus waves in both space and time [1]. An ideal TR mirror consists of a wave source located inside a lossless medium that is completely enclosed by a surface of transceivers, which record and absorb the signal initially broadcast by the sourc...
متن کاملAn Improved Time-Reversal-Based Target Localization for Through-Wall Microwave Imaging
Recently, time reversal (TR) method, due to its high functionality in heterogeneous media has been widely employed in microwave imaging (MI) applications. One of the applications turning into a great interest is through-wall microwave imaging (TWMI). In this paper, TR method is applied to detect and localize a target obscured by a brick wall using a numerically generated data. Regarding this, i...
متن کاملIterative angle-and-time-domain gating technique for time-reversal MUSIC imaging
This study develops the preprocessing theory for time-reversal multiple signal classification (TR-MUSIC) imaging from the one-dimensional (time-domain) gating proposed in earlier papers to a two-dimensional one. Although the one-dimensional gating technique for TR-MUSIC mitigates the effect of noise as well as reduces the required number of antenna elements, the resulting image is subject to fo...
