COPRIME ARRAYS WITH ENHANCED DEGREES OF FREEDOM

Anadolu University Journal of Science and Technology-A Applied Sciences and Engineering, 2018
Coprime array geometries provide robust performance for direction-of-arrival estimation problem with more sources than sensor elements. In previous works it is shown that K source directions can be resolved using only 2M + N -1 sensor elements where K is less than or equal to MN.

Direction‐of‐arrival estimation in coprime linear array using three uniform linear arrays considering mutual coupling

IET Radar, Sonar & Navigation
Nowadays, sparse arrays have been a focus for direction‐of‐arrival (DOA). The existing arrays can achieve high degree of freedom (DOF) bigger than the number of sensors when using the spatial smoothing methods.

Novel coprime MIMO configurations for DOA estimation with increased degrees of freedom

Franklin Open
In this work, we propose some coprime multiple input multiple output (MIMO) configurations for direction-of-arrival (DOA) estimation, which achieve more degrees of freedom (DOF) than all the existing coprime MIMO configurations. We know that in a coprime

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.
