【摘要】 2010年6月,中科院声学所声场声信息国家重点实验室在南海浅海区域进行了一次声学层析专题实验。实验综合使用声发射潜标、布设于海底的水平阵和潜标温度链同步记录了2天的声学和水文数据。对长时间实验观测数据进行了分析,研究了水平阵接收低频脉冲声信号反演海水声速剖面方法。结果表明:匹配场反演实验期间海水声速剖面与对应时刻的实测结果基本一致,声速标准差平均0.7 m/s,实现了较长时间内海水声速剖面的反演。更多还原

【Abstract】 An ocean acoustic tomography experiment was conducted in the South China Sea in June 2010.A bottom mounted horizontal line array was used to recording the signals from a low frequency source.Two temperature sensor arrays were moored near source and receiver array respectively and monitored the concurrent water column temperature variation.This paper analyzed the acoustic and water column data measured in the experiment.The matched field inversion was used to invert the sound speed profiles using low frequency pulse signals.The results show that the inverted sound speed profiles are agree well with the measured ones,and the mean of the root-mean-square errors is 0.7 m/s.更多还原
