Spatial time-frequency distribution of cross term-based direction-of-arrival estimation for weak non-stationary signal

EURASIP Journal on Wireless Communications and Networking, 2019
In the radar array signal processing direction of arrival (DOA), the estimation of weak non-stationary signal is an important and difficult problem when both strong and weak signals are coexisting particularly because the weak non-stationary signals are ...

Transmit Array Interpolation for DOA Estimation via Tensor Decomposition in 2D MIMO Radar

, 2017
In this paper, we propose a two-dimensional (2D) joint transmit array interpolation and beamspace design for planar array mono-static multiple-input-multiple-output (MIMO) radar for direction-of-arrival (DOA) estimation via tensor modeling.

Regularised Hyper Parameter Bi Level Optimisation With Continual Learning Based Deep Neural Network for Beamforming in Ultra‐Wide Band System

IET Communications, Volume 20, Issue 1, January/December 2026.
This research proposes a Regularised Hyperparameter Bilevel Optimisation with Continual Learning‐based Deep Neural Network (RHBO‐CLDNN) for beamforming in an Ultra‐Wide Band (UWB) system. The RHBO ensures the hyperparameter efficiency at both upper and lower levels, which allows DNN to fine‐tune the unique characteristics of the UWB system, which leads

Low‐Complexity DOA Estimation: Combining VSSLMS With FFT Spectrum Estimation

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This letter presents a novel, low‐complexity framework for DOA estimation. The proposed method achieves a significant reduction in computational complexity—from O(ML) to O(M log L)—compared to conventional SSE methods. Crucially, as illustrated in the accompanying figure, the method maintains high estimation accuracy, outperforming standard SSE‐based ...

Loop Matching Pursuit Multistation TDOA Estimation Method Based on Noncircular Signal

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
The existing TDOA estimation methods based on orthogonal matching pursuit only consider the scenario of circular signal and are prone to the degradation of estimation performance due to atom misselection under small samples and low signal‐to‐noise ratio.

Enhanced off-grid DOA estimation by corrected power Bayesian inference using difference coarray

The Journal of Engineering, 2019
Sparse Bayesian inference for on-grid direction-of-arrival (DOA) estimation using difference coarray was investigated in the authors’ previous work to estimate more signal sources than the number of physical antenna elements. Sparse Bayesian inference is
