Self-initiating MUSIC-based direction finding in underwater acoustic particle velocity-field beamspace
Abstract—This paper introduces a novel blind MUSIC-based (MUltiple SIgnal Classification) source localization algorithm ap- plicable to an arbitrarily spaced three-dimensional array of vector hydrophones , each of which comprises two or more co-located and orthogonally oriented velocity hydrophones plus an …

Particle-Velocity-Field Difference Smoothing for Coherent Source Localization in Spatially Nonuniform Noise
Abstract—This communication considers the problem of es- timating 2-D directions of arrival (DOAs) of multiple coherent signals under spatially nonuniform noise (spatially inhomogeneous temporary white noise) using an array of vector hydrophones .
