Abstract: The paper presents the time reversal signal processing for source localization based on finite difference time domain (FDTD) method with the help of MATLAB GUI. There are two simulation approaches to analyze for source location in a perfectly matched layer boundary. We have shown the energy spectrum for propagation of acoustics wave in a room to focus by using array of transducers and source. In these plots we first transmit the signals from the array of transducers to the source and then the signals can be retransmitted back from the source to the array of transducers by using time reverse algorithm. The reverse signals can be focused the location of source based on the proposed method and the localization pointer. The simulation results are evaluated to localize the source by using FDTD method in this work. The application areas of this work are mentioned in this work.
