Off-Grid DOA Estimation Using Sparse Bayesian Learning in MIMO Radar With Unknown Mutual Coupling
TL;DR: In this paper, a sparse Bayesian learning (SBL)-based method for estimating the direction of arrival (DOA) in a multiple-input and multiple-output (MIMO) radar system with unknown mutual coupling effect between antennas is investigated.
Journal ArticleDOI
A Novel Slot-Array Defected Ground Structure for Decoupling Microstrip Antenna Array
TL;DR: In this paper, a slot-array defected ground structure (DGS) is proposed for decoupling microstrip antenna array, which has the spatial bandstop characteristic and changes the direction of the partially coupled current, respectively.
Journal ArticleDOI
A New Atomic Norm for DOA Estimation With Gain-Phase Errors
TL;DR: A sparse model is formulated by exploiting the signal sparsity in the spatial domain and outperforms the existing methods, including the subspace-based and sparse-based methods in the scenario with gain-phase errors.
Journal ArticleDOI
DoA and DoD Estimation and Hybrid Beamforming for Radar-Aided mmWave MIMO Vehicular Communication Systems
TL;DR: A hybrid beamforming algorithm is proposed in the mmWave communication subsystem, which can overcome the shortage of the analog-only beamforming and reduce the beam search time, and the cell discovery time is improved significantly.
Journal ArticleDOI
Sparse DOD/DOA Estimation in a Bistatic MIMO Radar With Mutual Coupling Effect
TL;DR: Simulation results show that the proposed method can improve the DOD/DOA estimation in the scenario with unknown mutual coupling effect, and outperform state-of-the-art methods.
