COPRIME ARRAYS AND SAMPLERS FOR SPACE-TIME ADAPTIVE PROCESSING
, 2015 This paper extends the use of coprime arrays and samplers for the case of moving sources. Space-time adaptive processing (STAP) plays an important role in estimating direction-of-arrivals (DOAs) and radial velocities of emitting sources.

Sparse Sensing with Semi-Coprime Arrays
, 2018 A semi-coprime array (SCA) interleaves two undersampled uniform linear arrays (ULAs) and a $Q$ element standard ULA. The undersampling factors of the first two arrays are $QM$ and $QN$ respectively where $M$ and $N$ are coprime. The resulting non-uniform linear array is highly sparse.

Graph Topologies, Gap Metrics and Robust Stability for Nonlinear Systems
, 2005 Graph topologies for nonlinear operators which admit coprime factorisations are defined w.r.t. a gain function notion of stability in a general normed signal space setting.

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.

Efficient and Robust Adaptive Beamforming Based on Coprime Array Interpolation
Unlike uniform linear arrays (ULAs), coprime arrays require fewer physical sensors yet provide higher degrees of freedom (DOF) and larger array apertures.
