摘要：
The efficiency of time reversal acoustics may be strongly affected by attenuation in the presence of a very low Q-factor. This is particularly true when one-channel time reversal is implemented, taking advantage of virtual sources corresponding to the coda of the signal. To face this issue, in this paper, a procedure is proposed, which properly amplifies the recorded signals before back-propagation, in order to optimize both the quality of the focusing, in terms of signal-to-noise ratio, and the symmetry of the reconstructed signal.
