Two-Dimensional Angle Estimation of Two-Parallel Nested Arrays Based on Sparse Bayesian Estimation [PDF]
Sensors, 2018 To increase the number of estimable signal sources, two-parallel nested arrays are proposed, which consist of two subarrays with sensors, and can estimate the two-dimensional (2-D) direction of arrival (DOA) of signal sources.

Distributed Super Nested Arrays: Reduce the Mutual Coupling between Array Antennas
International Journal of Antennas and Propagation, 2021 In array, mutual coupling between the antennas is inevitable, which has an adverse effect on the estimation of parameters. To reduce the mutual coupling between the antennas of distributed nested arrays, this paper proposes a new array called the ...

Hole-Free Nested Array with Three Sub-ULAs for Direction of Arrival Estimation
Sensors, 2023 Sparse arrays are of deep concern due to their ability to identify more sources than the number of sensors, among which the hole-free difference co-array (DCA) with large degrees of freedom (DOFs) is a topic worth discussing.
