The US Navy, Naval Surface Warfare Center (NSWC) plans to upgrade its facilities at the Acoustic Research Detachment (ARD). Part of this upgrade includes installation of volumetric measurement arrays to characterize the radiated acoustic signatures of scale submarine models. At low and mid-frequencies the planned volumetric arrays will likely resemble those currently installed at the Southeast Alaska Acoustic Measurement Facility (SEAFAC) and the South TOTO Acoustic Measurement Facility (STAFAC). These arrays, however, do not extend into the high-frequency (HF) range above 10 kHz. The purpose of this SBIR is to develop an HF Volumetric Array conforming to the requirements given by NSWC. This array would eventually be integrated into the permanent test infrastructure at ARD.
