A beamforming method for multiple source DOA estimation, spectrum separation and localization from field data
Pages 123 - 124
Abstract
In this abstract, we present a beamforming method for estimating the directions and locations of multiple sources and separating each source's spectrum from field data collected by a wireless acoustic sensor network. Each acoustic sensor is equipped with four microphones that receive acoustic signals in a time-synchronized manner. The difference in time-of-arrival of proximal signals depends on the source direction with respect to the geometry of the microphone array. We show that by using beamforming in the frequency domain, the locations and Direction-Of-Arrivals (DOAs) of multiple 3D sources may be estimated, and the source spectrum may be separated from the audio data spectra.

DOA estimation based on fourth order cumulant beamforming for nonuniform linear array of DIFAR sonobuoys
The Directional Frequency Analysis and Recording (DIFAR) sonobuoy has been widely used in underwater target localization because it can capture more information than the Low Frequency Analysis and Recording (LOFAR) omnidirectional sonobuoy. Recently, ...
Source cancellation in cross-correlation functions for broadband multisource DOA estimation
Highlights- We present a technique to remove the effect of a source in the Generalized Cross-Correlation functions (GCCs) of a broadband sensor array.
AbstractIn multi-source localization systems, a stronger source can hide weaker sources. In this paper, we present a new technique to eliminate the effect of a source in the Generalized Cross-Correlation functions (GCCs) of the signals ...
Multiple Sound Source Separation by Jointing Single Source Zone Detection and Linearly Constrained Minimum Variance
ICCPR '20: Proceedings of the 2020 9th International Conference on Computing and Pattern RecognitionIn this work, a multiple speech source separation method is proposed based on single source zone detection and linearly constrained minimum variance (LCMV) beamformer. First, the "single-source" zones where only one source is dominant over the others ...
