A Review of Sparse Sensor Arrays for Two-Dimensional Direction-of-Arrival Estimation
IEEE Access, 2021 Two-dimensional (2D) arrays are fundamental to localization applications. Specifically, sparse arrays can provide superior direction-of-arrival (DoA) estimation performance with limited number of sensors. There has been increased interest in the research

ULA Fitting for Sparse Array Design [PDF]
IEEE Transactions on Signal Processing, 2021 Sparse array (SA) geometries, such as coprime and nested arrays, can be regarded as a concatenation of two uniform linear arrays (ULAs). Such arrays lead to a significant increase of the number of degrees of freedom (DOF) when the second-order information is utilized, i.e., they provide long virtual difference coarray (DCA).

The Analysis of Using Spatial Smoothing for DOA Estimation of Coherent Signals in Sparse Arrays
International Journal of Antennas and Propagation, 2021 When there is coexistence of uncorrelated and coherent signals in sparse arrays, the conventional algorithms for direction-of-arrival (DOA) estimation using difference coarray fail.

Low Discrepancy Sparse Phased Array Antennas
Sensors, 2021 Sparse arrays have grating lobes in the far field pattern due to the large spacing of elements residing in a rectangular or triangular grid. Random element spacing removes the grating lobes but produces large variations in element density across the ...

An L-Shaped Three-Level and Single Common Element Sparse Sensor Array for 2-D DOA Estimation
Sensors, 2023 The degree of freedom (DOF) is an important performance metric for evaluating the design of a sparse array structure. Designing novel sparse arrays with higher degrees of freedom, while ensuring that the array structure can be mathematically represented,

Sparse Convolutional Array for DOA Estimation
EURASIP Journal on Advances in Signal Processing, 2022 Abstract Array signal processing plays an important role in many areas. Besides the Uniform Linear Array, their are many sparse array that have been proposed, for example, Minimum-redundancy array, Co-prime array, nested array, etc. However, most of the array structures have certain disadvantages.
