Resolving Weak Sources within a Dense Array using a Network Approach
Nima Riahi, Peter Gerstoft
A non-parametric technique to identify weak sources within dense sensor arrays is developed using a network approach. No knowledge about the propagation medium is needed except tha…
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…
Using the LASSO's Dual for Regularization in Sparse Signal Reconstruction from Array Data
Christoph F. Mecklenbräuker, Peter Gerstoft, Erich Zöchmann
Waves from a sparse set of source hidden in additive noise are observed by a sensor array. We treat the estimation of the sparse set of sources as a generalized complex-valued LASS…
