声压振速联合信息处理及其物理基础初探

Study on the physical basis of pressure and particle velocity combined processing

研究了水声场声压和振速联合信息处理的一些基础问题，如声压和振速的相关性，平均声强器和指向性的旋转和锐化等。通过理论分析和湖试结果对声压振速联合信息处理技术进行了初步的探讨。

Some basic studies of pressure and particle velocity combined Processing such as correlation between them,average acoustic intensity processing, rotatioll and sharping of directivity are described in this paper. Primary resultsbased on theoretical analysis and lake trail are put forward and this will make foundation for further research.
