The benefits of terahertz (THz) radiation have increased its use, especially in imaging
systems. Recently, the use of a linear sparse periodic array (SPA) has been proposed as an …

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 …

Among image reconstruction methods, Fourier transform-based techniques provide
computationally better performance. However, conventional Fourier-based reconstruction …

As it is known, existing mixed near‐field and far‐field non‐circular source localisation rely on
the uniform linear array (ULA). Compared with the ULA, the sparse array can obtain more …

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 …

Waveforms used in multiple‐input multiple‐output (MIMO) systems must be considered in
such a way that individual transceiver (T‐R) pairs can be separated from the composite …

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 …

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 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 …

In passive localization techniques, as the scale of the array of the sensors used increases,
the source distribution may be a coexistence of near-field (NF) and far-field (FF) sources …
