摘要
水声环境包括海洋中影响声信号传播的各种参数,传统上,这些参数的测量都是由从事水声及其设备研究的专业人员进行,而且需要许多实验室测量仪器,所以,一直被称为水声实验。就如何将海洋水声参数的测量工程化,实现多航次、大面积的高效率水声调查,对信号获取方法、信号分析与处理方法进行了探索性研究,并在专门的数据处理软件研制中,对提出的联合时频分析法进行了验证。
Acoustic environment includes ocean' s various parameters, affecting acoustic signals' transmission. Traditionally, measurement of these parameters is carried out by the professionals who are engaged in water and its equipment research, and needs many laboratory measuring instruments. Therefore, it has been called the acoustic experiment. This paper does some exploratory researches about how to improve the measure of ocean acoustic parameters engineering, implementing highly efficient acoustic survey of multivoyage and a large area, and also researches the method of signal acquisition, analysis and processing. This paper validates the JTFA by specialized data processing soft.
