The radar signature of the Wind Lens: a less disruptive wind turbine? [PDF]

, 2012
We study the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a flanged shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency.

Time Synchronisation for Passive Bistatic HFSWR via Kalman‐Filtered Delay‐Locked Loop

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper proposes a per‐chirp time synchronisation method, FLOS‐Kalman‐DLL, for passive bistatic high‐frequency surface wave radar (HFSWR) operating under the coexistence of clock drift and atmospheric impulsive noise. The method combines fractional lower‐order statistics with a Kalman‐filtered delay‐locked loop to achieve sub‐sample synchronisation ...

Intelligent Systems for Beyond‐Line‐of‐Sight Defense Communication: Technologies, Case Studies, and Research Frontiers

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Beyond‐line‐of‐sight (BLOS) communication is a fundamental component of modern defense strategies, enabling secure and reliable information exchange in environments where traditional line‐of‐sight (LOS) methodologies are ineffective due to obstructions or operational constraints.

Comparative Analysis of Aroma Compositions in Chestnut Whiskeys Produced by Five Commercial Yeasts Using E‐Nose and GC‐IMS

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.
To investigate the adaptability of commercially available whiskey yeasts when fermented with nontraditional raw materials, this study conducted a comparative analysis of the fermentation and volatile production characteristics of five commercial yeasts, namely, Angel W19, Fermentis D53, Fermentis M1, RED STAR 11b, and Still Spirits Distiller’s Whisky ...

Decoding Brain Tumors: Comprehensive Insights into Detection and Evaluation Approaches

Engineering Reports, Volume 7, Issue 12, December 2025.
Comparison of brain tumor analysis techniques reveals that hybrid and ensemble models offer superior accuracy and generalization, while traditional ML provides higher interpretability and lower computational cost. This radar chart highlights the trade‐offs across five critical performance dimensions.

Advancing Ensemble Streamflow Prediction Through Satellite‐Based Precipitation Product and Model Parameter Uncertainty Quantification

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.
Abstract Satellite‐based quantitative precipitation estimates (QPE), such as NASA's Integrated Multi‐satellitE Retrievals for GPM (IMERG), provide easily accessible continental‐to‐global precipitation forcings for flood prediction and other hydrologic applications.

Fault Network Geometry Modulates Earthquake Source Spectra Across Scales

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Earthquake source spectra provide unique insights into the earthquake rupture process. Motivated by previous research suggesting that complex fault geometries enhance high‐frequency seismic radiation, we study the influence of fault network geometry on earthquake source spectra using multiple independent observations.

MIMO noise radar - matched filters and coarrays [PDF]

, 2008
Copyright © 2008 IEEEThe noise radar concept can be extended to an array of K transmit antenna and M receive antenna. When independent noise sources are transmitted from each antenna the approach may be viewed as a special case of MIMO radar and matched ...
