A combined BP‐MF algorithm for wideband off‐grid DOA estimation with DP prior
Electronics Letters, 2022 Direction‐of‐arrival (DOA) estimation based on sparse Bayesian learning (SBL) framework has attracted extensive attention. The accuracy of on‐grid DOA estimation is restricted by the prescribed grid, while off‐grid approaches resolves the problem of grid

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

Unraveling the Phenomenon of Supply‐Demand Feedback in Agricultural Water Interventions
Earth's Future, Volume 13, Issue 10, October 2025.Abstract The Agricultural water interventions can trigger human‐water feedback, including unintended supply demand feedback—where increased water availability drives greater water use. In the Kamadhiya catchment, India, the introduction of check dams (CDs) led to a shift toward more water‐intensive crops like cotton and wheat. This study formulates and

Direction-of-Arrival Estimation of Virtual Array Signals Based on Doppler Effect
International Journal of Distributed Sensor Networks, 2015 The estimation accuracy of direction-of-departure (DOD) and direction-of-arrival (DOA) is reduced because of Doppler shifts caused by the high-speed moving sources.

Polynomial Manifold Interpolation for Direction Finding in the Presence of Mutual Coupling
IEEE Access, 2019 Direction-of-arrival (DOA) estimation in the presence of mutual coupling among the antennas is an important problem in direction finding systems. To address the mutual coupling issue, a polynomial manifold interpolation approach is proposed in this paper.
