基于光纤水听器的声场水平相关性研究

Study of horizontal correlation based on fiber-optic hydrophone

中科院声学研究所声场声信息国家重点实验室与长沙国防科技大学合作研制出了一条32阵元的光纤水听器阵,并于2002年8月在渤海进行了一次海上实验。本文利用光纤水听器阵获得的气枪声信号进行了声场的水平相关性分析,并与理论结果进行了比较,实验和理论结果基本符合。

A 32-element fiber optic hydrophone horizontal line array was designed and developed by the State Key Laboratory of Institute of Acoustics, the Chinese Academy of Sciences, and the National University of Defense Technology. In August 2002, it was successfully used in measuring the underwater signals in an experiment, which was conducted in the Bohai Sea. The horizontal correlations of acoustics were analyzed from the measured signals and were in good agreement with the theoretical results.
