The problem of passive localization of mixed near-field (NF) and far-field (FF) source signals
in the presence of array gain-phase uncertainties is addressed. A new algorithm is aimed to …

Most works in the literature on parameter estimation with multiple-input multiple-output
(MIMO) systems are limited to estimating only the direction of arrival (DOA), and/or based on …

In this paper, we investigate the problem of estimating the directions-of-arrival (DOAs) and
ranges of multiple narrowband near-field sources in unknown spatially nonuniform noise …

As we all know, nested array can obtain a larger array aperture and more degrees of
freedom using fewer sensors. In this study, we not only designed an enhanced symmetric …

This paper investigates the classification and localization of the mixed far-field sources
(FFSs) and near-field sources (NFSs) on a symmetrical uniform linear array and proposes a …

In this paper, a one-step method is proposed for the classification and estimation of the
parameters in the scenario of mixed near-field and far-field stationary sources. By …

Direction-of-arrival (DOA) estimation plays a crucial role in array signal processing across
various domains, including radar, sonar, wireless communications, and seismic exploration …

This communication presents an efficient iterative approach for locating the near-field (NF)
coherent sources. In each iteration, the covariance matrices only containing single source …

This work presents an effective and robust methodology to achieve the joint estimation of
direction-of-arrival (DOA) and range. One or more near-field sources are the signals of …

Unlike passive detection in the far-field where the array steering vector depends only on
direction-of-arrival (DOA), in the near-field (NF) since the shape of the spherical wavefront …
