Recently, nested and coprime arrays have attracted considerable interest due to their
capability of providing increased array aperture, enhanced degrees of freedom (DOFs), and …

Recently, nonuniform linear arrays (eg, coprime/nested array) have attracted great attention
of researchers in array signal processing field due to its ability to generate virtual difference …

Sparse linear arrays (SLAs) can be designed in a systematic way, with the ability for
underdetermined DOA estimation where a greater number of sources can be detected than …

As an indispensable part of the Internet of Vehicles (IoV), unmanned aerial vehicles (UAVs)
can be deployed for target positioning and navigation in the space–air–ground-integrated …

In the practical radar with multiple antennas, the antenna imperfections degrade the system
performance. In this paper, the problem of estimating the direction of arrival (DOA) in a …

As a generalized coprime array structure, the coprime array with displaced subarrays
(CADiS) allows a large minimum inter-element spacing by introducing a specific …

It is a serious problem that the performance loss is suffered by traditional Direction-of-Arrival
(DOA) estimation methods in non-ideal environment, such as mutual coupling of array …

Existing sparse array (SA) geometries, such as coprime and nested arrays, can be regarded
as a concatenation of two uniform linear arrays (ULAs). Such arrays lead to a significant …

The recent criteria of a preferable linear sparse array for a robust direction of arrival (DOA)
estimation are: the closed-form expression for its sensor locations; the large central uniform …

In sensor array processing, the minimum sensor/element-spacing is usually restricted within
a half-wavelength in order to avoid estimation aliasing. This would cause sensor/element …
