Three-Parallel Co-Prime Polarization Sensitive Array for 2-D DOA and Polarization Estimation via Sparse Representation

open access: yesIEEE Access, 2019
Co-prime array configurations are considered attractive due to the extension of degrees of freedom (DOFs) and the sparse placement of array elements. In this paper, a 2-D direction-of-arrival (DOA) and polarization estimation algorithm are proposed with ...

Modified root MUSIC for co‐prime linear arrays [PDF]

open access: yesElectronics Letters, 2018
The direction of arrival (DOA) estimation problem using co‐prime linear arrays is studied. By analysing the special array geometry of the co‐prime array, the co‐prime array is taken as a filled uniform linear array where some elements are omitted, then a modified root‐multiple signal classification (MUSIC) algorithm is developed, which avoids the ...

Sparse Low-redundancy Linear Array with Uniform Sum Co-array [PDF]

open access: yes, 2020
Sparse arrays can resolve vastly more scatterers than the number of sensors in tasks such as coherent source localization. This entails significant cost reductions compared to conventional arrays with uniformly spaced elements.

Sparse direction of arrival estimation of co-prime MIMO radar using sparse aperture completion

open access: yesThe Journal of Engineering, 2019
In this study, the authors consider the problem of direction of arrival (DOA) estimation in compressive sensing multiple-input and multiple-output (CS-MIMO) radars with co-prime receive arrays. A sparse aperture completion scheme is proposed to fill the ‘

Fast estimation of direction of arrival based on sparse Bayesian learning for towed array sonar during manoeuvring

open access: yesIET Radar, Sonar & Navigation, 2023
For improving performance of the towed array sonar during the manoeuvring period, a processing framework is proposed based on joint estimation of direction of arrival (DOA) and the array shape.

2-D DOA estimation method based on coprime array MIMO radar

open access: yesEURASIP Journal on Advances in Signal Processing, 2021
Aiming at the problem that traditional direction of arrival (DOA) estimation methods cannot handle multiple sources with high accuracy while increasing the degrees of freedom (DOF), a new method for 2-D DOA estimation based on coprime array MIMO radar ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Symmetric sparse linear array for active imaging [PDF]

open access: yes, 2018
Sparse sensor arrays can achieve significantly more degrees of freedom than the number of elements by leveraging the co-array, a virtual structure that arises from the far field narrowband signal model.
