2 May 2006The design of a broadband ocean acoustic laboratory: detailed examination of vector sensor performance
Acoustic vector sensors measure the acoustic pressure and three orthogonal components of the acoustic particle acceleration at a single point in space. These sensors, and arrays composed of them, have a number of advantages over traditional hydrophone arrays. This includes full azimuth/elevation angle estimation, even with a single sensor. It is of interest to see how in-water vector sensor performance matches theoretical bounds. A series of experiments designed to characterize the performance of vector sensors operating in shallow water was conducted to assess sensor mounting techniques, and evaluate the sensor's ability to measure bearing and elevation angles to a source as a function of waveform characteristics and signal-to-noise ratio.
