Abstract
En 中文
Iterative Time Reversal (TR) procedures have been demonstrated to be successful in detecting scatterers even in a highly reverberant environment. The success or the method is attributable to a Time Reversal Mirror (TRM) consisting of an array or transceivers that allows one to reconstruct and reverse-propagate wavefronts of interest. This paper deals with the limiting case or a TRM reduced to a single transceiver, tested using a tank experiment with three scattering objects in free-field conditions. It is shown that it is possible to excite a resonance between the TR operator and the strongest mode of the target in the bandwidth of insonification. A simple free-field scattering model is used to study the mechanisms of convergence and to drive the physics-based analysis of data.
