Extended abstract: Second-order quantity sensitivities of underwater acoustic dyadic sensors combined with accelerometers
Proceedings of the 8th ACM International Conference on Underwater Networks and Systems, WUWNet 2013(2013)
摘要
The sensitivity of an underwater acoustic sensor is the most important characteristic to measure in a calibration experiment. In this paper, a theoretical sensitivity formulation for the second-order quantities of underwater acoustic dyadic sensors combined with accelerometers are presented. A dyadic sensor combined with accelerometers is made and measured in an anechoic tank. The experimental results indicate that the sensitivity curves of the two types of acceleration gradient are generally consistent with the theoretical curves.
