Sparse Planar Array Beamforming via ADMM Optimization with Mutual Coupling Mitigation

2026 7th International Conference on Inventive Research in Computing Applications (ICIRCA)
The present work utilizes full-wave electromagnetic models of realistic patch antenna elements to propose an effective sparse planar array beamforming framework that explicitly takes mutual coupling into consideration.

Target localization with coprime multistatic MIMO radar via coupled canonical polyadic decomposition based on joint eigenvalue decomposition

Signal Processing
This paper investigates target localization using a multistatic multiple-input multiple-output (MIMO) radar system with two distinct coprime array configurations: coprime L-shaped arrays and coprime planar arrays.

Coarray Tensor Train Decomposition for Bistatic MIMO Radar With Uniform Planar Array

IEEE Transactions on Antennas and Propagation
Recently, tensor network decomposition has attracted increasing attention due to its high efficacy in modeling multidimensional correlations in high-order tensors. Considering this advantage, this study employs tensor train decomposition (TTD) to achieve

WLB-CANUN: Widely Linear Beamforming in Coprime Array With Non-Uniform Noise

IEEE Transactions on Vehicular Technology
The performance of widely linear beamforming (WLB) is superior to adaptive beamforming, but it is limited by the uniform linear array geometry and non-uniform noise. In this paper, to overcome these limitations together, we propose a framework for widely

Bilateral Multi-Subarray Padded Coprime Array Configuration for DOA Estimation in MIMO Radar

IEEE Transactions on Vehicular Technology
Simultaneous consideration of uniform degrees of freedom (uDOF) and mutual coupling is a key focus in sparse array design. To reduce mutual coupling and increase degrees of freedom (DOF), a bilateral multi-subarray coprime array (BMSCA) is proposed with ...
