Abstract
Acoustical time reversal mirror principles are described in review papers of M. Fink, the inventorof TRM, and his associates. In Recent Choi carried out the study of the waveform and spatialfocusing experiment. In this paper it is considered the approach to predict TRM parameters based on the calculations of impulse response from underwater acoustic ray model(Bellhop) in shallow water. Acoustic TRM(Time Reversal Mirror) is useful tool for sound focusing and sound sourcelocalization. TRM simulation is carried out to send the high acoustic energy to a sound source location in shallow water for underwater acoustic communication. An ideal TRM simulation iscompared with the experimental simulation using the field data of shallow water in Korea.dered the approach to predict TRM parameters based on the calculations of impulse response from underwater acoustic ray model(Bellhop) in shallow water.
