The objective of this article is to present the work carried out on source localization in the open sea using a Vector Sensor Array (VSA) with three elements, developed by the National Institute of Ocean Technology. In order to ascertain the performance of the VSA in the open sea, first a known source transmission– reception experiment was conducted. After completion of measurements at sea, the VSA was maintained in the mooring at the same location, for collection of ambient noise data. The results obtained from the data analysis demonstrate a fairly good performance of VSA in underwater source localization.
