Wideband array signal processing

, 2003
Array processing has played an important role in many diverse application areas such as radar, sonar, radio astronomy, seismology, tomography, speech, communication etc. As early as World War II,phased array radars have been used. Most modern radar and sonar systems rely on antenna arrays or hydrophone arrays as an essential component to estimate the ...

Cost-effective aperture arrays for SKA Phase 1: single or dual-band?

, 2012
An important design decision for the first phase of the Square Kilometre Array is whether the low frequency component (SKA1-low) should be implemented as a single or dual-band aperture array; that is, using one or two antenna element designs to observe ...

Interleukin‐6 as a Key Biomarker in Facioscapulohumeral Dystrophy: Evidence From Longitudinal Analyses

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Facioscapulohumeral muscular dystrophy type 1 (FSHD1) is a progressive neuromuscular disorder with no approved treatments. Identifying reliable biomarkers is critical to monitor disease severity, activity, and progression. Interleukin‐6 (IL‐6) has been proposed as a candidate biomarker, but longitudinal validation is limited ...

Rapid Target Search Method for Distributed Aperture Radar via Role Reversal

IET Radar, Sonar & Navigation
Distributed aperture radar (DAR) systems encounter significant computational challenges in near‐field target detection because of the large synthesised equivalent apertures which drastically increase scan cell dimensionality and processing complexity. To

SNUPN‐Related Muscular Dystrophy: Novel Phenotypic, Pathological and Functional Protein Insights

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective SNUPN‐related muscular dystrophy or LGMDR29 is a new entity that covers from a congenital or childhood onset pure muscular dystrophy to more complex phenotypes combining neurodevelopmental features, cataracts, or spinocerebellar ataxia. So far, 12 different variants have been described.

Noncoherent Channel Combining for GNSS Signal Tracking with an Adaptive Antenna Array

Remote Sensing
Adaptive antenna arrays are widely used to protect Global Navigation Satellite System (GNSS) receivers from interference. However, conventional blind anti-jamming array processing methods can cause satellite signal attenuation, which reduces signal ...

Copy Number Variants and Their Association With Intracerebral Hemorrhage Risk: A Case–Control Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Intracerebral Hemorrhage (ICH) is a leading cause of morbidity and mortality worldwide and lacks effective therapeutic interventions. Despite previous studies, the genetic underpinnings of ICH remain poorly understood. We sought to investigate the role of copy number variants (CNVs) in ICH pathophysiology to identify novel ...
