Hydrophone Array Articles & Analysis

A hydrophone array comprises several hydrophones strategically placed in known locations, such as in a line on the seafloor, moored vertically in the water column, or towed horizontally behind a vessel. ...
To monitor these changes, an instrument composed of an omnidirectional transmitter and an array of hydrophones was built. With frequencies ranging between 10 and 110 kHz, high resolution is achieved in the vertical direction enabling the detectability of clogged layers with a minimum thickness of 1 cm. ...
The location system developed to address this need utilises signal Time of Arrival Differences (TOADs) between hydrophone pairs, which confines the signal source to a hyperboloid. Through the use of a sufficient number of receivers, the resultant intersecting hyperboloids can be analysed using a 'surface search' routine to determine source location. The results presented show the ...
