Semi-Coprime Array with Staggered Beam-Steering of Sub-Arrays [PDF]
Sensors, 2023 A split-aperture array (SAA) is an array of sensors or antenna elements in which the array is split into two or more sub-arrays (SAs). Recently proposed SAAs, namely coprime and semi-coprime arrays, offer to attain a small half-power beamwidth (HPBW ...

Sparse Sensing with Semi-Coprime Arrays [PDF]
The Journal of the Acoustical Society of America, 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

Thinned coprime arrays for DOA estimation [PDF]
2017 25th European Signal Processing Conference (EUSIPCO), 2017 Sparse arrays can generate a larger aperture than traditional uniform linear arrays (ULA) and offer enhanced degrees-of-freedom (DOFs) which can be exploited in both beamforming and direction-of-arrival (DOA) estimation. One class of sparse arrays is the
