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

Symmetric Displaced Coprime Planar Array for Two-Dimensional Direction-of-Arrival Estimation
IEEE Sensors Journal, 2022Recently, sparse planar arrays have been developed to improve the 2-D direction-of-arrival (DOA) estimation performance by their superiorities in the degree of freedom (DOF), array aperture, and mutual coupling over uniform planar arrays. In this article,

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.

The coprime planar array (CPPA) can obtain a larger virtual aperture using the sum-difference co-array (SDCA). Nonetheless, the holes in the SDCA always cause the virtual aperture to be not fully utilized. In order to solve this issue, a two-dimensional (

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 ...
