L-Shaped Sparse Array Structure for 2-D DOA Estimation
IEEE Access, 2020 In order to improve the performance of two-dimensional (2-D) direction-of-arrival (DOA) estimation, an L-shaped sparse array structured by two new sparse linear arrays is proposed. Each part of the proposed L-shaped array is used for one-dimensional (1-D)

Optimization of Sparse Cross Array Synthesis via Perturbed Convex Optimization
Sensors, 2020 Three-dimensional (3-D) imaging sonar systems require large planar arrays, which incur hardware costs. In contrast, a cross array consisting of two perpendicular linear arrays can also support 3-D imaging while dramatically reducing the number of sensors.

Journal of Telecommunications and Information Technology, 2021 Regular fully filled antenna arrays have been widely used in direction of arrival (DOA) estimation. However, practical implementation of these arrays is rather complex and their resolutions are limited to the beamwidth of the array pattern.
