Witryna1 lis 2007 · 1. Introduction [2] Time reversal has attracted considerable attention in recent years, particularly because of its potential for communication and imaging through a complex environment. When a wave is emitted by a point source and is received by an array of receivers, and time-reversed and back-propagated in the same medium, the … WitrynaThe enhanced spatial focusing and time compression of signals in time reversal in random media have many diverse applications in detection and in focused energy …

Imaging and Time Reversal in Random Media - CORE

WitrynaThis is a new approach to array imaging that is motivated by time reversal in random media, analysed in detail previously. It combines features from seismic imaging, like … WitrynaThis is a new approach to array imaging that is motivated by time reversal in random media, analysed in detail previously. It combines features from seismic imaging, like ATA, with frequency-domain signal subspace methodology like multiple signal classification. We illustrate the theory with numerical simulations for ultrasound. how do bays and headlands form

In order to refine the design and hence increase the long-term reliability, there has been … WitrynaThis is a new approach to array imaging that is motivated by time reversal in random media, analysed in detail previously. It combines features from seismic imaging, like … Witrynay the resolution of time reversal and imaging. Since they occur in random media, the resolution theory is augmented with the important concept of statistical stability. It refers to robustness of the processes with respect to di erent realizations of the random medium. Description.
