Measuring Reflection Coefficient of Underwater Acoustic Materials with the Vector Hydrophone

摘要: Reflection coefficient of underwater materials can be calculate by measuring impedance above the sample. some techniques which measure reflection are based on sound pressure. This paper introduces a method for with vector hydrophone instantaneous pressure and particle velocity. Then calculated is acquired Some simulations experiments in this show that have good performance coefficient, minimum error 0.006. It prove effective both vertical oblique incidence, handy practice.
