Advanced ASW Acoustic Transducers and Signal Processing

Preliminary development of a noise audit model for vector sensor towed arrays will be performed and is focused on tasks related to validating an analytical model of a thin-line array. An in-house numerical code known as the duct transmission line (DTL) modeling tool will be adapted for specific application to towed arrays having periodic impedance discontinuities. Flow noise mitigation techniques designed to remove the flow noise signal from pressure gradient hydrophones will be further developed. Data from an upcoming tow test will be used to help validate the model. Evaluation of these concepts will facilitate component-level and system-level requirements for next generation directional sensors and arrays. Surveillance platforms targeted for commercialization of this technology include the TB-23 and TB-29 submarine towed arrays and the AN/WSQ-11 surface ship towed array.
