Abstract

For simulation to time reversed acoustic inversion in any enclosure system as shallow water, we must know the impulse response of the system. Throughout this process we can reproduce an original signal at focal point by convolution of time reversed inversion. To apply this TRA simulation to shallow water environment, after extracting the impulse response about simple condition as shallow water, we analyze the acoustic focusing by TRA inversion. In result, the spatial focusing and time signal patterns can be built by TRA simulation for shallow water condition. [Supported by KORDI (Korea Ocean Research & Development Institute)]
