Nabil Mohsen, Ammar Hawbani, Xingfu Wang, Benjamin Bairrington, Liang Zhao, Saeed H. Alsamhi

ICASSP 2023accepted

Recently, sparse arrays have received considerable attention owing to their capability of achieving increased degrees of freedom (DoFs) by exploiting the virtual sensors resulting from their difference or sum-difference coarrays. Mutual coupling is another factor that attracts interest to these kind…

A New Coprime-Array-based Configuration with Augmented Degrees of Freedom and Reduced Mutual Coupling

Nabil Mohsen, Ammar Hawbani, Monika Agrawal, Saeed H. Alsamhi, Liang Zhao

ICASSP 2022accepted

In this paper, a new type of coprime-array-based structure, named AtCADiS, is proposed to achieve increased degrees of freedom (DoFs) and reduced mutual coupling. The closed-form expressions for the sensor positions and the number of uniform DoFs (uDoFs) of AtCADiS are provided. Specifically, AtCADi…
