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

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 …

In recent years, the sources localization has noticed an increase in research conducted on
the problem of mixed far-field sources (FFSs) and near-field sources (NFSs). The main …

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 …

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 …

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 novel method called fourth-order spatiotemporal algorithm (FOSA) is
presented for classification, 2D DOA estimation and 3D localization of mixed near-field and …

Conventional decorrelation techniques that resolve all signals simultaneously are not
efficient in mixture scenarios of non-coherent and coherent signals. In newer methods for …

To locate mixed far-field (FF) and near-field (NF) sources, most existing methods require two
or three steps to first find the direction-of-arrival (DOA) and then retrieve the range …
