Adaptive processing method for interference cancellation in sky-wave OTHR

The Journal of Engineering, 2019
An algorithm is proposed to cancel the spatially non-stationary high-frequency (HF) interference in the returns of sky-wave over-the-horizon radar (OTHR).

Evaluation of Polyolefin Encapsulants for Roll‐to‐Roll Lamination Applications

Progress in Photovoltaics: Research and Applications, EarlyView.
Polyolefin encapsulants, PO1 and PO3, show best compatibility with R2R lamination, balancing flow, thermal properties and aging resistance. ABSTRACT Mass Customization (MC) in photovoltaic (PV) manufacturing enables the production of diverse, cost‐effective integrated PV products through the use of semi‐fabricates.

Climatological model of over-the-horizon radar (CMOR)

, 2017
Models of radar systems are required for a variety of reasons. The sophistication of these models is highly dependant on their purpose; for instance microwave radar models which are designed to be integrated into existing wargaming simulation frameworks ...

The benefit of neighborhood methods for the assimilation of cloud‐affected radiances evaluated in observing‐system simulation experiments

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Neighborhood methods are commonly used in verification to avoid the double‐penalty issue. This study evaluates such methods for the assimilation of infrared and visible satellite observations and extends them to multiscale assimilation. Moreover, a novel technique is tested aimed at mitigating complex biases and structural errors in real‐world model ...

Towards a Cognitive Radar: Canada’s Third-Generation High Frequency Surface Wave Radar (HFSWR) for Surveillance of the 200 Nautical Mile Exclusive Economic Zone

Sensors, 2017
Canada’s third-generation HFSWR forms the foundation of a maritime domain awareness system that provides enforcement agencies with real-time persistent surveillance out to and beyond the 200 nautical mile exclusive economic zone (EEZ).

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...

DETERMINING THE DISTANCE TO THE TARGET IN PASSIVE RADAR OF SURFACE OBJECTS [PDF]

Radio Physics and Radio Astronomy
Subject and Purpose. While outperforming active radar methods for range, stealth, and energy consumption, passive radar has a significant disadvantage: it cannot determine the target distance and coordinates when only one reference receiving point is ...

Object‐based deep learning for probabilistic convective‐core nowcasting from satellite data

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Convective cores detected from Meteosat infrared imagery are represented as compact physical objects to generate probabilistic nowcasts up to 6 h ahead. A spatio‐temporal transformer models interactions among evolving core populations and produces gridded probability forecasts across the western Sahel.

Fundamental aspects of netted radar performance [PDF]

, 2010
Netted radar employs several spatially distributed transmitters and receivers for information retrieval. This system topology offers many advantages over traditional monostatic and bistatic systems which use a single transmitter and a single receiver ...
