Abstract

For simulation of acoustic source localization using time reversal mirror(TRM) in the shallow water, we must know the impulse response of the environment. Throughout this process we can reproduce an original signal at focal point.To apply this TRM simulation to shallow water environment, after extracting the impulse response about simple condition as shallow water, we analyze the acoustic focusing by TRM inversion. In result, the source localization could be built by TRM simulation for shallow water condition.ly this TRM simulation to shallow water environment, after extracting the impulse response about simple condition as shallow water, we analyze the acoustic focusing by TRM inversion.
