Research Institution
During the Phase I Base Effort, an omni-directional hydrophone will be designed and tested for prospective use in a ULF sonobuoy application. The design will be based on a sensor that was previously developed for an unrelated ULF application, but will generally fit within design envelope of the AN/SSQ-53F calibrated omni. The Base Effort will also entail evaluation of three different hydromechanical suspension systems that are adaptations of the suspension system employed by the AN/SSQ-53F DIFAR sonobuoy. The overall sonobuoy system architecture will also be developed during the Base Effort and will largely be driven by the hydrophone and hydromechanical suspension system design. The Phase I Option will entail an in situ evaluation of the hydrophone and hydromechanical suspension system at ultra-low frequencies. A majority of the experiments will be performed at the Lapel Test Facility operated by USSI.
