Abstract:Seafloor is an important boundary for underwater sound field, and its acoustic scattering property has significant influence to spatial structure and distribution of underwater sound field. In this paper, we systematically analyzed and summarized the present progress on the measuring techniques, mechanism and modeling of bottom acoustic scattering property in the world. In addition, some research directions and topics which should be paid more attention to in the future were put forwarded as well as some research difficulties. This work will have great contribution to further studying and understanding the present status and the future trend of the research on bottom acoustic scattering property.
Keywords:bottom acoustic scattering property  scattering model  bottom reverberation  underwater sound field
