Autonomous underwater unmanned vehicular recovery system based on low-cost inter-aural time differentiation passive sonar

Abstract

Abstract-Sensing systems for AUVs are deeply researched but post mission deployment recovery systems for these vehicles are equally important. This paper presents a lowcost recovery system designed to provide post mission recovery location discovery capabilities to AUVs. The recovery system discussed relies on inter-aural time differentiation of sonar pulses received by the AUV from a sonar beacon.
