This paper presents a comprehensive review of hydrophones, their design considerations,
physical aspects, and structures by reviewing many publications that have been published …

Aperture extension (interferometry baseline extension) is achieved in this novel ESPRIT-
based two-dimensional (2-D) arrival angle estimation scheme using a sparse (aka, thin or …

Most array-processing methods require knowledge of the correlation structure of the noise.
While such information may sometimes be obtained from measurements made when no …

A sparse uniform Cartesian-grid array suffers cyclic ambiguity in its Cartesian direction-
cosine estimates due to the spatial Nyquist sampling theorem. The proposed MUSIC-based …

This paper introduces a new underwater acoustic eigenstructure ESPRIT-based algorithm
that yields closed-form direction-of-arrival (DOA) estimates using a single vector …

This paper introduces a novel blind MUSIC-based (MUltiple SIgnal Classification) source
localization algorithm applicable to an arbitrarily spaced three-dimensional array of vector …

This article presents a new method for 3-D localization of an acoustic source signal by
estimating its azimuth-angle, elevation-angle, and radial range. The proposed method …

In order to improve the angular resolution of direction-of-arrival (DOA) estimation based on
portable microphone at low signal-noise-ratio (SNR), this paper proposes a new high …

In acoustic sensing systems, acoustic vector sensor (also known as vector hydrophone for
underwater applications) arrays are widely used. Most of the acoustic vector sensor array …

We consider the passive direction-of-arrival (DOA) estimation problem using arrays of
acoustic vector sensors located in a fluid at or near a reflecting boundary. We formulate a …
