Key Challenges in True Multistatic OTH Radar Concepts based on HF-Radar in iFURTHER

The system concept of a multistatic network of collaborative high frequency (HF) over-the-horizon (OTH) radar nodes has been proposed and is being tested in the European Union-funded study iFURTHER.

Modelling a Networked Over the Horizon Radar

, 2021
We have proposed an over the horizon radar (OTHR) architecture with receiving systems which are truly relocatable and mobile. This networked OTHR (NOTHR) is based on a beamforming on transmit concept. It proposes a very large aperture antenna on transmit

Licence Loss: Revocations of Residential Care Licences in Four Nordic Countries

Child &Family Social Work, EarlyView.
ABSTRACT With placement in residential care, society assumes overall responsibility for a child's daily care, well‐being and development. How public authorities respond to poor care quality is of crucial importance. To guarantee quality care and minimise risks, welfare states increasingly develop different mechanisms and systems to supervise out‐of ...

Extremely Long‐Range Observations of Ionospheric Irregularities in a Large Longitude Zone From Pacific to Africa Using a Low Latitude Over‐The‐Horizon Radar in China

Geophysical Research Letters
Monitoring the generation and movement of equatorial plasma bubbles (EPBs) in a large longitude region is crucial important for better understanding their day‐to‐day variability. Using the newly developed Low lAtitude long Range Ionospheric raDar (LARID)

Controls on ERS altimeter measurements over ice sheets: Footprint-scale topography, backscatter fluctuations, and the dependence of microwave penetration depth on satellite orientation

, 2001
We consider the reliability of radar altimeter measurements of ice sheet elevation and snowpack properties in the presence of surface undulations. We demonstrate that over ice sheets the common practice of averaging echoes by aligning the first return ...

Using a System-Theoretic Approach for Cyber Mission Assurance of the Royal Canadian Air Force Over the Horizon Radar System

, 2023
Since 1958, the North American Aerospace Defence between Canada and the United States remains as the only bi-national military command in the world. Among many of its responsibilities, the need for early detection of threats against the North American ...

How Regulatory Costs Impede Financial Technology Gains

European Financial Management, EarlyView.
ABSTRACT While financial technology innovation lowers intermediation costs, regulatory frictions may prevent these gains from reaching long‐term investors and borrowers. Using variation in retail investor participation driven by state securities registration lapses in peer‐to‐peer lending, we demonstrate that regulatory frictions are associated with ...

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, EarlyView.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.
