High Resolution Krylov Space 3-D Wavenumber-Frequency Analysis

Abstract

Driven by the need for identifying the presence of flow noise components in a towed volumetric acoustic array, methodologies are developed for high resolution 3-dimensional (3-D) wavenumber-frequency (k-f) analysis based on Krylov space techniques. These methods are applied to actual noise data from a sea trial. The experimental results indicate that the Krylov-based method outperforms conventional approaches and provides efficient and effective solutions to k-f analysis.
