Distributed acoustic sensing for ocean applications
Angeliki Xenaki, Peter Gerstoft, Ethan Williams +1
Extensive monitoring of acoustic activities is important for many fields, including biology, security, oceanography, and Earth science. Distributed acoustic sensing (DAS) is an evo…
An Overview of Advances in Signal Processing Techniques for Classical and Quantum Wideband Synthetic Apertures
Peter Vouras, Kumar Vijay Mishra, Alexandra Artusio-Glimpse +4
Rapid developments in synthetic aperture (SA) systems, which generate a larger aperture with greater angular resolution than is inherently possible from the physical dimensions of…
Multi Snapshot Sparse Bayesian Learning for DOA Estimation
Peter Gerstoft, Christoph F. Mecklenbräuker, Angeliki Xenaki
The directions of arrival (DOA) of plane waves are estimated from multi-snapshot sensor array data using Sparse Bayesian Learning (SBL). The prior source amplitudes is assumed inde…
Grid-free compressive beamforming
Angeliki Xenaki, Peter Gerstoft
The direction-of-arrival (DOA) estimation problem involves the localization of a few sources from a limited number of observations on an array of sensors, thus it can be formulated…
Multiple and single snapshot compressive beamforming
Peter Gerstoft, Angeliki Xenaki, Christoph F. Mecklenbräuker
For a sound field observed on a sensor array, compressive sensing (CS) reconstructs the direction-of-arrival (DOA) of multiple sources using a sparsity constraint. The DOA estimati…
