Unmanned aerial vehicle (UAV) has been widely used in many fields and is arousing global
attention. As the resolution of the equipped sensors in the UAV becomes higher and the …

As is well known, nonuniform linear arrays have significant advantages in array aperture
and degrees of freedom over uniform linear arrays. Using their difference coarrays …

In this paper, we address the problem of joint direction-of-arrival (DoA) and range estimation
using frequency diverse coprime array (FDCA). By incorporating the coprime array structure …

In this letter, we devise an efficient approach for estimating the directions-of-arrival (DOAs) of
coherent signals using coprime arrays. Specifically, we firstly derive an augmented uniform …

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

Uniform linear array (ULA) fitting (UF) principle is a newly proposed sparse array (SA)
design scheme that aims to design SAs using cascaded ULAs, based on which a number of …

Conventionally, mixed near-field (NF) and far-field (FF) source localization is performed
using a symmetric uniform linear array (ULA). Recently, two symmetric nonuniform linear …

Nested arrays have recently attracted a growing concern owing to their ability of achieving
extended aperture and enhanced degrees of freedom (DOFs) compared to conventional …

A novel sparse array (SA) structure is proposed based on the maximum inter-element
spacing (IES) constraint (MISC) criterion. Compared with the traditional MISC array, the …

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 …
