Intermediate scale measurement system for underwater acoustic measurements

The Intermediate Scale Measurement System (ISMS) provides high quality acoustic measurements on large-scale submarine models and other underwater structures in a controlled environment. Development and implementation of advanced marine technology designs require a thorough understanding of structural acoustic response mechanisms. The only practical and cost effective approach to developing this understanding is through the use of a combination of numerical models and large-scale physical models. The ISMS provides an affordable, unique capability of making precision acoustic measurements on models large enough to contain the structural detail and the instrumentation required to understand structural acoustic mechanisms and to confirm and guide the use of numerical models. This is a key element for prediction of full-scale performance and integration of advanced submarine technologies into operational systems.
