Propagations Recorded with Vector Sensors and its Application
Vector sensor has attracted much attention in recent years. However, there are few papers analyzing the sound propagations recorded with vector sensors in detail. In this research, several experiments have been performed to measure sound propagation with vector sensors. The theoretical analysis and the data indicate that vector hydrophones can provide more information of sound propagation than traditional pressure hydrophones. A Geoacoustic inversion scheme employing a vector hydrophone array has been developed. The inversion scheme is the combination of the Matched Field Processing and the difference of transmission losses between pressure and velocity. The advantages of this method are that it can decrease the uncertainty of the inverted sediment sound speed and the inversion of the sediment attenuation is independent of the source level.
