Array Signal Processing Based on Traditional and Sparse Arrays [PDF]
, 2019 Array signal processing is based on using an array of sensors to receive the impinging signals. The received data is either spatially filtered to focus the signals from a desired direction or it may be used for estimating a parameter of source signal ...

Super Nested Arrays: Linear Sparse Arrays with Reduced Mutual Coupling - Part I: Fundamentals
, 2016 In array processing, mutual coupling between sensors has an adverse effect on the estimation of parameters (e.g., DOA). While there are methods to counteract this through appropriate modeling and calibration, they are usually computationally expensive ...

Parameters estimation with coprime samplers and arrays
Les réseaux et les capteurs éparse attirent de plus en plus l'attention en raison de leur capacité à augmenter les DOFs. La DOA ou la fréquence des signaux peut être estimée avec peu de capteurs d'antenne ou quelques échantillons sub-Nyquist collectés.

Robustness of Difference Coarrays of Sparse Arrays to Sensor Failures - Part II: Array Geometries
, 2019 In array processing, sparse arrays are capable of resolving O(N^2) uncorrelated sources with N sensors. Sparse arrays have this property because they possess uniform linear array (ULA) segments of size O(N^2) in the difference coarray, defined as the ...
