Direction of Arrival Estimation Using Augmentation of Coprime Arrays

Information, 2018
Recently, direction of arrival (DOA) estimation premised on the sparse arrays interpolation approaches, such as co-prime arrays (CPA) and nested array, have attained extensive attention because of the effectiveness and capability of providing higher ...

Direction of arrival estimation for BLE: Antenna array design and evaluation

AEU - International Journal of Electronics and Communications, 2023
The use of smart antenna arrays in wireless communication systems is becoming increasingly popular, as they improve the performance of the radio link and allow the integration of communication and sensing functions. In this paper, we present the design and performance evaluation of a uniform circular antenna array (UCAA) with 12 monopole antennas and ...

Enhancing polynomial MUSIC algorithm for coherent broadband sources through spatial smoothing [PDF]

, 2017
Direction of arrival algorithms which exploit the eigenstructure of the spatial covariance matrix (such as MUSIC) encounter difficulties in the presence of strongly correlated sources.

Direction of arrival measurements at UHF

Electronics Letters, 1989
Direction of arrival measurements have been made at 870 MHz in an urban environment. Examples are given showing the multipath components arriving at the receiver after reflection and scattering from buildings. A synthetic aperture technique is used to measure the directions of arrival.

Direction of arrival estimation using nonsingular spherical ESPRIT [PDF]

The Journal of the Acoustical Society of America, 2018
The eigenbeam-ESPRIT (EB-ESPRIT) is a parametric method that estimates the direction of arrival of source signals using a recurrence relation of spherical harmonics. In EB-ESPRIT, the sound-source elevation angle is estimated from an arctangent function, which diverges near the equator in the spherical coordinate system and inevitably induces an ill ...

Approximate maximum likelihood direction of arrival estimation for two closely spaced sources [PDF]

, 2013
—Most high resolution direction of arrival (DoA) estimation algorithms exploit an eigen decomposition of the sample covariance matrix (SCM). However, their performance dramatically degrade in case of correlated sources or low number of snapshots.

An enhanced expanding and shift sparse array based on the coprime array and nested array

IET Radar, Sonar & Navigation
In recent years, sparse arrays based on the fourth‐order difference coarray (FODCA) have received increased research attention due to their small number of array elements and large consecutive virtual arrays.
