FDA-MIMO radar for 3D localization: Virtual coprime planar array with unfolded coprime frequency offset framework and TRD-MUSIC algorithm

Digital Signal Processing, 2021
Abstract The frequency diverse array multiple-input multiple-output (FDA-MIMO) radar can detect target range by exploiting a small frequency offset across the transmit sensors, which can be utilized to jointly estimate angle and range. Nevertheless, the detection performance is basically restricted by the array aperture and signal bandwidth.

Generalized Coprime Planar Array Geometry for 2-D DOA Estimation

IEEE Communications Letters, 2017
In this letter, we propose a generalized coprime planar array (GCPA) geometry for 2-D direction of arrival (DOA) estimation, where two rectangular uniform planar subarrays are used. The proposed geometry allows a more flexible array layout and extends the array aperture to achieve a great performance improvement. We verify that GCPA can obtain a higher

Two-dimensional DOA Estimation for Coprime Planar Array: A Coarray Tensor-based Solution

ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020
Coprime arrays can cope with the underdetermined case for direction-of-arrival (DOA) estimation. However, the popular matrix-based coarray signal processing approaches suffer performance loss on the underlying characteristics among the multi-dimensional signals.

A DOA Tracking Algorithm for Coprime Planar Array via PAST

2018 4th Annual International Conference on Network and Information Systems for Computers (ICNISC), 2018
Compared to traditional planar arrays, coprime planar arrays have more precise direction finding precision and higher degrees of freedom. As there is little research on DOA tracking of arbitrary dynamic targets in coprime arrays, a DOA tracking algorithm based on Projection Approximation Subspace Tracking (PAST) for coprime planar array is proposed. It

Recursive Extended Instrumental Variable Based LCMV Beamformers for Planar Radial Coprime Arrays Under Spatially Colored Noise

IEEE Transactions on Aerospace and Electronic Systems, 2021
This article proposes a new recursive linearly constrained minimum variance (LCMV) beamformer based on the extended instrumental variable (EIV) method for planar radial coprime arrays (PRCAs) under spatially colored noise. The proposed recursive LCMV beamformer is able to deal with multiple constraints with high precision and low complexity and can be ...
