Statistics Direction -of -arrival estimation performance of sparse linear arrays GEORGE MASON UNIVERSITY Kristine Bell KhanDibaDirection-of-arrival (DOA) estimation involves estimating the angle of arrival of a plane wave or multiple plane waves observed by an array of sensors. This problem arises in...
Numerical tests, referred to benchmark problems, show that that proposed synthesis method is able to achieve maximally sparse linear arrays, also compared with the best results reported in the literature, obtained by means of global optimization schemes....
In this letter, the unitary matrix pencil (UMP) method is utilized for the shaped-beam pattern synthesis of maximally sparse linear arrays. Taking advantage of the equivalent matrix pencil obtained by a unitary transformation, the UMP-based synthesis method constructs a novel relation between the el...
The Wolfram Language has special sparse-array technology for efficiently handling arrays with literally astronomical numbers of elements when only a small fraction of the elements are nonzero. The Wolfram Language's linear algebra and all standard list operations can be done in symbolic form onSparseA...
Sparse Symmetric Linear Arrays with Contiguous Sum and Difference Co-array Although several sparse array configurations have been developed for passive sensing applications, far fewer active array designs exist. In active sensing, the sum co-array is typically more relevant than the difference co-array...

Sparse arrays have emerged as a popular alternative to the conventional uniform linear array (ULA) due to the enhanced degrees of freedom (DOF) and superior resolution offered by them. In the passive setting, these advantages are realized by leveraging correlation between the received signals at di...
Here, we experimentally show that such reconstruction also leads to super-resolution in both PA and US imaging with arrays having much less elements than used conventionally (sparse arrays). As a proof of concept, we obtained super-resolution PA and US cross-sectional images of microfluidic ...
With the advent of nested array (NA) [18] and coprime array (CA) [26], the problem of designing sparse linear arrays has gained a renewing interest, mainly along the line of advancing the closed-form NA/CA criteria, for increased uDOF and reduced antenna mutual coupling. For example, ...
