TLM 모델링을 이용한 수중 통신 채널 구현에 관한 연구

Abstract

We can easily build up a sound channel with a Image Method, while the speed of sound and the surface of water , the ocean floor are same. On the contrary ,We can build up it with a Ray Method, while the speed of sound and the surface of water, the ocean floor are different, like the real ocean. We use TLM modelling to make it up a propagation channel of sound wave characteristic . First , we investigated the efficiency of TLM through simulation show from the changes of medium. and compared the result of Image Method with simulation is being used TLM Modelling in each environment from medium. according to as above, we will find out that we can build up a communication channel in the water, while the source and the receiver move , like a real ocean environment.
