dc.description.abstractThis dissertation focuses on new developments and applications of timereversal (TR) signal processing techniques for acoustic waves in the case of multiple input channels. It is well known that the acoustic wave equation in a non-dissipative medium contains a second-order time-derivative operator, which in turn is invariant under a TR operation. Therefore, the TR is a novel technique that can employ backpropagation of the wave to focus energy onto a specific location in space and time. This is because back-propagated waves can retrace all of the complex paths such as reflection, refraction and multiple scattering that they underwent during the forward propagation. Thus, it results in highly focusing onto the initial source location. Based on this property, there has been a strong interest in the application of TR techniques in a broader topic of the acoustic field. Thus, the motivation of our dissertation is to develop new algorithms based on the TR technique for applying in some important topics of the acoustic field, including acoustic focusing, acoustic detection and localization, acoustic inverse scattering as well as stereophonic acoustic echo cancellation.en_US
