The acoustic vector-sensor is a practical and versatile sound-measurement system, for applications in-room, open-air, or underwater. Its <i>far</i>-field measurement model has been introduced into signal processing over a decade ago; and many direction-finding algorithms have since been developed for acoustic vector-sensors, but only for <i>far</i>-field… (More)

An acoustic vector-sensor (AVS) consists of 1) an acoustic pressure-sensor, and 2) a velocity-sensor triad of three identical but orthogonally oriented acoustic velocity-sensors, all spatially colocated in a point-like geometry. Each acoustic velocity-sensor has an intrinsically directional response to the incident acoustic particle-velocity wavefield,… (More)

Herein investigated are computationally simple microphone-array beamformers that are independent of the frequency-spectra of all signals, all interference, and all noises. These beamformers allow the listener to tune the desired azimuth-elevation "look direction." No prior information is needed of the interference. These beamformers deploy a physically… (More)

This work extends the ‘geometric modelling’ of channel fading to account for the effects of the polarisation states of the transmitting/receiving antennas, and for the distribution of the direction of arrival of the uplink multipaths. The derived formulas are closed-form functions, explicitly in terms of a few model parameters idealising the spatial… (More)

For a directional (a.k.a. directive) transceiver misaligned towards an omni-directional transceiver, the multipaths’ time-of-arrival (TOA) distribution is herein derived in closed form explicitly in terms of the “geometric modeling" parameters. This derivation allows the directional beamwidth to mis-point to any arbitrary azimuth-direction, even if entirely… (More)

The paper analyzes how a sensor array’s direction-finding accuracy may be degraded by any stochastic uncertainty in the sensors’ complex value gains, modeled here as complex value Gaussian random variables. This analysis is via the derivation of the hybrid Cramér-Rao bound (HCRB) of the azimuth-elevation direction-of-arrival estimates. This HCRB is… (More)

The acoustic vector-sensor (a.k.a. the vector hydrophone) is a practical and versatile sound-measurement device, with applications in-room, open-air, or underwater. It consists of three identical uni-axial velocity-sensors in orthogonal orientations, plus a pressure-sensor-all in spatial collocation. Its far-field array manifold [Nehorai and Paldi (1994).… (More)

A new adaptive “beamforming” signal-processing algorithm is developed to locate the loudest noise sources aboard a railcar that passes by a trackside immobile microphone array. This proposed microphone-array beamformer tracks the railcar’s spatial movement with the aid of two inaudible acoustic beacons placed aboard the railcar. The proposed scheme then… (More)

In an array of antennas, the inter-antenna electromagnetic mutual coupling, unless properly corrected, would degrade an antenna array's performance in direction finding. In the special case of a uniformly spaced linear array of identical antennas, Azarbar, Dadashzadeh & Bakshi have suggested discarding the antennas' collected data at both ends of the… (More)
