Abstract Direction-Of-Arrival (DOA) estimation in environments with coherent sources is a
challenging problem, when the number of narrowband sources is more than elements and …

In this paper, the problem of two-dimensional (2-D) direction-of-arrival (DOA) estimation for
incoherently distributed (ID) noncircular sources is addressed. A low-complexity estimator …

This paper reviews and compares three different decorrelation methods for Direction-of-
Arrival (DOA) estimation of coherent sources, these include Real-Value (RV), Spatial …

The covariance matrix of the array output is widely used for direction-of-arrival (DOA)
estimation in array signal processing. However, the existing methods are only suitable for …

Based on TLS-ESPRIT algorithm, this paper proposes a weighted spatial smoothing DOA
estimation algorithm to address the problem that the conventional TLS-ESPRIT algorithm …

We address the 2D direction-of-arrival (DOA) estimation problem in scenarios with coherent
sources. More specifically, we adopt beamforming solutions based on the iterative adaptive …

Purpose–The purpose of this paper is to develop a new method for the two‐dimensional
direction‐of‐arrival (DOA) estimation of multiple coherently distributed (CD) sources, which …
