Adaptive time-reversal mirror.

چکیده
The time-reversal mirror uses the received signal from a probe source to refocus the signal at the probe source location by backpropagating the time-reversed version of the received signal. In this study, an adaptive method is described to steer a null to an arbitrary position in a waveguide while maintaining a distortionless response at the probe source location. As an application, selective focusing in free space is demonstrated.

A Parametric Study of an Implementing Adaptive Time Reversal Mirror as a Crosstalk Mechanism for Underwater Communication
The time reversal mirror technique has been widely applied to mitigate the inter-symbol interference in underwater channels. Meanwhile, an adaptive time reversal mirror is introduced to improve the crosstalk quality between receivers in underwater acoustic communication (UAC). However, array configuration affects the performance of this mechanism. To explore the effectiveness of this method, th...
متن کاملEnvironmentally adaptive reverberation nulling using a time reversal mirror
Backscattering from the rough water-bottom interface can serve as a surrogate probe source in time reversal. A time-gated portion of the reverberation then is refocused to the bottom interface at the corresponding range @Lingevitch et al., J. Acoust. Soc. Am. 111, 2609–2614 ~2002!#. In this paper, reverberation nulling is investigated to enhance active target detection without a priori knowledg...
متن کاملA Numerical Investigation of the Time Reversal Mirror Technique for Trans-skull Brain Cancer Ultrasound Surgery
Introduction: The medical applications of ultrasound on human brain are highly limited by the phase and amplitude aberrations induced by the heterogeneities of the skull. However, it has been shown that time reversing coupled with amplitude compensation can overcome these aberrations. In this work, a model for 2D simulation of the time reversal mirror technique is proposed to study the possibil...
متن کاملExperimental demonstration of adaptive reverberation nulling using time reversal
The concept of environmentally adaptive reverberation nulling using a time reversal mirror TRM recently has been described Song et al., J. Acoust. Soc. Am. 116, 762–768 2004 . In this paper, monostatic reverberation nulling is demonstrated experimentally at 850 and 3500 Hz using data from a shallow water experiment conducted off the west coast of Italy in April 2003. The active transmission of ...
متن کاملDamage imaging in a laminated composite plate using an air-coupled time reversal mirror
We demonstrate the possibility of selectively imaging the features of a barely visible impact damage in a laminated composite plate by using an air-coupled time reversal mirror. The mirror consists of a number of piezoelectric transducers affixed to wedges of power law profiles, which act as unconventional matching layers. The transducers are enclosed in a hollow reverberant cavity with an open...
