摘要
As the ocean technology in deep water is paid much more attention than that in shallow water, the target detection techniques used in deep water are also attracting much more attention. So far, only the acoustic signal is favorable for long-distance transmission in the water. An ocean acoustic technology based on the property of the sound propagation is the key for the breakthrough of the target detection range of the sonar. This paper gives an overview on the basic acoustic propagation paths and passive localization methods used in deep water. The aim is to advance the fundamental research on acoustic signal processing.
