Direction finding by sparse‐based approach for dual‐polarised conformal array in the presence of gain and phase uncertainties

open access: yesIET Radar, Sonar & Navigation, 2023
This article investigates the problem of robust direction‐of‐arrival (DOA) estimation with unknown sensor gain and phase uncertainties. A Dual‐Polarised Regularised Multiple FOCal Underdetermined System Solver is proposed to estimate the 2‐D DOA for the ...

Power-Based Direction-of-Arrival Estimation Using a Single Multi-Mode Antenna

open access: yes, 2017
Phased antenna arrays are widely used for direction-of-arrival (DoA) estimation. For low-cost applications, signal power or received signal strength indicator (RSSI) based approaches can be an alternative. However, they usually require multiple antennas,

Stochastic framework for evaluating the effect of displaced antenna elements on DOA estimation [PDF]

open access: yes, 2017
We establish a statistical framework for investigating the influence of correlated random displacements of antenna elements in a uniform circular antenna array (UCA) on the distribution of direction-of-arrival (DOA) estimates. More specifically, we apply

A Simple Cross Correlation Switched Beam System (XSBS) for Angle of Arrival Estimation

open access: yesIEEE Access, 2017
We propose a practical, simple and hardware friendly, yet novel and efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation-based system requires a switched beam antenna array with a single radio frequency ...

Spatially localized direction of arrival estimation

open access: yesProceedings : European Conference on Noise Control, 2018
Direction-of-arrival (DOA) estimation is a fundamental area of research in the field of array processing, as it applies in a variety of areas, including: sound field analysis, spatial sound reproduction and spatial filtering. There exists a plethora of DOA estimating algorithms, which all vary in terms of accuracy and computational complexity.

Predicting the Future Burden of Renal Replacement Therapy in Türkiye Using National Registry Data and Comparative Modeling Approaches

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic kidney disease is a growing public health problem worldwide, and the number of patients requiring renal replacement therapy is steadily increasing. Türkiye has experienced a similar rise in both the incidence and prevalence of renal replacement therapy over the past decades; however, national‐level projections of future ...

Quantum approach to direction of arrival estimation

open access: yesТехнологія та конструювання в електронній апаратурі
The article analyses methods for determining the direction of arrival (DOA) of radio signals, particularly the MUSIC and ESPRIT algorithms. It is shown that the complexity of traditional approaches grows cubically with the number of antennas, which ...
