Abstract : The miniature acoustic vector sensor (AVS) incorporates, along with a hydrophone, 3-axis accelerometers whose output can be integrated to give local fluid particle velocity information. In principle, a single AVS can give unambiguous bearing information, and multiple vector sensors used in arrays of moderate size can improve spatial resolution. The use of AVS on small autonomous vehicles holds great promise for battlespace as well as oceanographic information gathering, but there are fundamental difficulties and compromises involved in the integration with a moving vehicle of an instrument responsive to particle accelerations in the surrounding medium.
