水声学研究进展

Advances of research work in underwater acoustics

声学是一门古老而又年轻的科学，水声学是声学的一个分支。本文介绍近年来水声学研究的主要进展。包括新型水声换能器材料、水中非线性声学、匹配场过滤、宽容性信号处理、水声通信、合成孔径成象技术、数据融合、声层析、水下ＧＰＳ技术等。文中还介绍了军事海洋学和基于模型的声呐设计等新概念。

Accostics is an ancient and young science, underwater acowtics is a branch of acoustics. The advances of researeh in recent years are discussed in this paper. Which include new type of transducer materials, non-linear underwater acoustics, matched filter processing, robust signal processing, underwater communication, synthetic aperture imaging technique, data fusion, acoustic tomography, underwater GPS technique etc. Some new concept and idea, such as military oceanography model-based sonar design, are also reviewed in this paper.
