A Novel Sparse Array for Localization of Mixed Near-Field and Far-Field Sources
International Journal of Antennas and Propagation, 2021 As we all know, nested array can obtain a larger array aperture and more degrees of freedom using fewer sensors. In this study, we not only designed an enhanced symmetric nested array (ESNA), which achieved more consecutive lags and more unique lags ...

On the existence of nested orthogonal arrays
Discrete Mathematics, 2008 An orthogonal array \(\text{OA}(N,k,s,g)\) has \(N\) rows, \(k\) columns, \(s\) symbols, and strength \(g\) if it is an \(N \times k\) array with entries from an \(s\)-set in which every possible combination of symbols appear equally often as rows in every \(N \times g\) subarray.

DOA Estimation Using Fourth-Order Cumulants in Nested Arrays with Structured Imperfections
Sensors, 2020 Recently developed super nested array families have drawn much attention owing to their merits on keeping the benefits of the standard nested arrays while further mitigating coupling in dense subarray portions.

Beamforming using passive nested arrays of sensors [PDF]
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010 A novel approach to beamforming using a new class of sensor arrays is proposed, which can increase the achievable degrees of freedom significantly beyond the conventional limits obtained from uniform linear arrays (ULA). This class of arrays is named as "nested arrays" since they are obtained by nesting two or more ULAs with increasing inter-sensor ...

Direction of Arrival and Polarization Estimation for Nested Polarization Sensitive Array
IEEE Access, 2019 This paper presents a new polarization sensitive array composed of a two-level nested subarray and an optimally nested subarray with orthogonal oriented antennas, and then proposes a correlation matrix reconstruction based estimation method for direction

Statistical Nested Sensor Array Signal Processing [PDF]
, 2015 Source number detection and direction-of-arrival (DOA) estimation are two major applications of sensor arrays. Both applications are often confined to the use of uniform linear arrays (ULAs), which is expensive and difficult to yield wide aperture ...

IEEE Access, 2018 Sparse arrays have potential advantages over their regularly spaced counterparts, but they will generate undesired grating lobes. This paper investigates a sparse linear phased-array for grating lobe suppression and arbitrary transmit-receive beampattern
