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...
In coastal areas, the properties of the soft sediment are crucial for sound propagation prediction and relevant sonar applications. The noise of intense ship traffic is a convenient acoustic source in these areas for geoacoustic characterization. This paper introduces a sequential particle filter (PF) technique that can take advantage of the continuous ship sound field to predict the soft sediment...
