Electronics Letters, Volume 61, Issue 1, January/December 2025.This letter proposes a hybrid approach that combines model‐driven and data‐driven theories to strike a balance between estimation performance and computational cost. We reconstruct a structured covariance matrix by applying adaptive diagonal loading.

Electronics Letters, Volume 61, Issue 1, January/December 2025.This letter proposes a novel RI‐ResNN‐DAE framework based on deep residual learning for DOA estimation under the mixture of impulsive and nonuniform Gaussian noise, which adapts well to unknown modulation schemes. The relationship between angular resolution and the weights of deep learning model is firstly analyzed.

A Tensor-Based Subspace Approach for Bistatic MIMO Radar in Spatial Colored Noise
Sensors, 2014 In this paper, a new tensor-based subspace approach is proposed to estimate the direction of departure (DOD) and the direction of arrival (DOA) for bistatic multiple-input multiple-output (MIMO) radar in the presence of spatial colored noise.

Joint 2D-DOA and Frequency Estimation for L-Shaped Array Using Iterative Least Squares Method
International Journal of Antennas and Propagation, 2012 We introduce an iterative least squares method (ILS) for estimating the 2D-DOA and frequency based on L-shaped array. The ILS iteratively finds direction matrix and delay matrix, then 2D-DOA and frequency can be obtained by the least squares method ...
