Vector sensors have attracted extensive interest for their abilities to measure the scalar acoustic pressure field and particle velocity at a single location in space. During a deep-water experiment held in the South China Sea in 2014, a vector sensor placed at the depth of 3146 m received the experimental signals launched from a towed transducer at 140 m depth. In the direct-arrival zone of the sound...
In this paper two single receivers are used for pulsed source ranging. A pressure field propagation from a point source in shallow water can be expressed as modes summation by Pekeris's theory. It is known that the group delay difference and group speed of each mode can be used to estimate the range of the source, and the group speed of each mode requires environmental information to be known. The...
