Non-Circular Signal DOA Estimation with Nested Array via Off-Grid Sparse Bayesian Learning
Sensors, 2023 For the traditional uniform linear array (ULA) direction of arrival (DOA) estimation method with a limited array aperture, a non-circular signal off-grid sparse Bayesian DOA estimation method based on nested arrays is proposed.

IEEE Access, 2019 Linear sparse arrays (coprime and nested arrays) have been studied extensively as a means of performing direction of arrival (DoA) estimation while bypassing Nyquist sampling theorem. However, rectangular sparse arrays have few studies, most of which are

Design of Novel Nested Arrays Based on the Concept of Sum-Difference Coarray
, 2020 Nested arrays have recently attracted considerable attention in the field of direction of arrival (DOA) estimation owing to the hole-free property of their virtual arrays.

Auxiliary Results of Collection and Classification of Surface Geoelectric Arrays [PDF]
, 2007 Recently, we have made a classification of more than one hundred various surface geoelectric arrays ever published in geophysical literature (Szalai and Szarka 2007a, 2007b). The classification is based on three divalent parameters (as “superposition” of

Extension of nested arrays with the fourth-order difference co-array enhancement [PDF]
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016 To reach a higher number of degrees of freedom by exploiting the fourth-order difference co-array concept, an effective structure extension based on two-level nested arrays is proposed. It increases the number of consecutive lags in the fourth-order difference coarray, and a virtual uniform linear array (ULA) with more sensors and a larger aperture is ...

Design and Statistical Analysis of Tapered Coprime and Nested Arrays for the Min Processor
IEEE Access, 2019 Coprime and nested arrays are sparse sensor arrays that provide O(MN) degrees of freedom using only O(MN) sensors. The signals sampled by these sparse arrays contain the aliasing artifact; the min processor is used to disambiguate this aliasing artifact.

Sparse Billboard and T-Shaped Arrays for Two-Dimensional Direction of Arrival Estimation
IEEE Open Journal of Signal Processing, 2023 In two-dimensional direction of arrival (2D-DOA) estimation, planar arrays can estimate the elevation and azimuth angles simultaneously. However, many planar array topologies such as billboard, L-shaped, T-shaped, and 2D nested arrays suffer from mutual ...

Balanced nested designs and balanced arrays
Discrete Mathematics, 2002 The interdependencies between different types of designs and arrays are studied. Basic concepts include balance, nesting of designs and symmetry. Related concepts used in constructions include Wilson theory, ordered designs, group-divisible designs and frames.

Construction of some new families of nested orthogonal arrays
, 2018 Nested orthogonal arrays have been used in the design of an experimental setup consisting of two experiments, the expensive one of higher accuracy being nested in a larger and relatively less expensive one of lower accuracy. In this paper, we provide new
