Abstract:

This report documents efforts to develop theory and experimental demonstration of the use of compact arrays of hydrophones for the purpose of reducing the effect of flow noise in undersea applications. Results indicate that in many circumstances, significant processing gain can be achieved over simple spatial averaging as achieved with flush-mounted patch hydrophones of equivalent cross-sectional area.
