摘要：

This paper presents our preliminary geoacoustic inversion results of the ship noise data collected by a vector sensor in 2008, Dalian, China. For the at-sea measurement, a fishing boat was served as a passive source passed by the receiver boat deploying a vector sensor, which collected the pressure field and particle velocity components at three orthogonal directions of X, Y and Z. A batch inversion scheme is adapted to optimize a Bartlett type cost function that comprises the range-dependent sound propagation features. The results from the pressure, vertical particle velocity component and the combination of them are presented, which suggests the combination processing can provide better inversion results.
