Robust Direction-of-Arrival Estimation for Coprime Array in the Presence of Miscalibrated Sensors
IEEE Access, 2020 Coprime arrays have been widely adopted for direction-of-arrival (DOA) estimation since it can achieve an increased number of degrees of freedom (DOF).

Enhanced CACIS configuration for direction of arrival estimation
Electronics Letters, 2022 In this letter, an enhanced coprime array with compressed inter‐element spacing is designed for direction of arrival estimation. First, we analyse and conclude that the 0th sensor of coprime array with compressed inter‐element spacing is redundant for ...

Spatial Information and Performance Evaluation in Coprime Array [PDF]
Mathematical Problems in Engineering, 2020 In this paper, the mutual information between the received signals and the source in the coprime linear array is investigated. In Shannon’s information theory, the mutual information is used to quantify the reduction in the priori uncertainty of the transmitted message.

Super Nested Arrays: Sparse arrays with Less Mutual Coupling than Nested Arrays [PDF]
, 2016 In array processing, mutual coupling between sensors has an adverse effect on the estimation of parameters (e.g., DOA). Sparse arrays, such as nested arrays, coprime arrays, and minimum redundancy arrays (MRAs), have reduced mutual coupling compared to ...
