Hole-Free Nested Array with Three Sub-ULAs for Direction of Arrival Estimation [PDF]
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.

Non-Circular Signal DOA Estimation with Nested Array via Off-Grid Sparse Bayesian Learning [PDF]
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.

Computationally Efficient Sources Location Method for Nested Array via Massive Virtual Difference Co-Array [PDF]
Sensors, 2019 In this paper, we derive the discrete Fourier transform (DFT) method for direction of arrival (DOA) estimation by generating the massive virtual difference co-array with the nested array. By contrast with the spatial smoothing (SS) subspace-based methods

A Novel PARAFAC Model for Processing the Nested Vector-Sensor Array
Sensors, 2018 In this paper, a novel parallel factor (PARAFAC) model for processing the nested vector-sensor array is proposed. It is first shown that a nested vector-sensor array can be divided into multiple nested scalar-sensor subarrays.

An Improved Adaptive Received Beamforming for Nested Frequency Offset and Nested Array FDA-MIMO Radar [PDF]
Sensors, 2018 For the conventional FDA-MIMO (frequency diversity array multiple-input-multiple-output) Radar with uniform frequency offset and uniform linear array, the DOFs (degrees of freedom) of the adaptive beamformer are limited by the number of elements.

The Multi-Level Dilated Nested Array for Direction of Arrival Estimation
IEEE Access, 2020 In this paper, a more generalized dilated nested array (DNA) named multi-level dilated nested array (multi-level DNA), which further extends the original DNA to the general situation and improves the direction of arrival (DOA) estimation performance, is ...

Nested perfect toroidal arrays
CoRR, 2023 We introduce two-dimensional toroidal arrays that are a variant of the de Bruijn tori. We call them nested perfect toroidal arrays. Instead of asking that every array of a given size has exactly one occurrence, we partition the positions in congruence classes and we ask exactly one occurrence in each congruence class.
