Source Localization by Simulation of Time Reversal Wave and Its Resolution Improvement with Deconvolution Technique
We propose a source localization method based on a simulation of the time reversal wave. The fundamental principle has already been proposed. In this paper, the principle is applied to the sound field surrounded by reflective boundaries. The resolution is limited due to the length of the driving signal in ordinary way. However, the resolution can be improved by deconvolution technique if the waveform of the sound source is known. The proposed method can possibly be applied to acoustical flaw detection. In this paper, the source localization is only simulated numerically. We are planning experimental verifications in the future.
