A Cognitive Beamforming Method via Range-Doppler Map Features for Skywave Radar
Remote Sensing, 2022 For skywave over-the-horizon radar, beamforming techniques are often used to suppress airspace radio frequency interference because the high-frequency band is shared by many devices.

Fuzzy Functional Dependencies as a Method of Choice for Fusion of AIS and OTHR Data
, 2019 Maritime situational awareness at over-the-horizon (OTH) distances in exclusive economic zones can be achieved by deploying networks of high-frequency OTH radars (HF-OTHR) in coastal countries along with exploiting automatic identification system (AIS ...

Modeling the Impact of Sporadic-E on Over-the-Horizon Radar (OTHR) in the Polar Region [PDF]
Recent studies have highlighted the frequent occurrence of sporadic-E (Es) layers—thin, localized zones of enhanced electron density—especially in high-latitude and polar regions. To address this, a new statistical model for Es has been incorporated into

Earth's Future, Volume 14, Issue 11, November 2026.Abstract Monsoon Low‐Pressure Systems (LPSs) that govern the rainfall of the Indian Summer Monsoon (ISM) contribute more than half of its rainfall and extreme rainfall events. In this study, we explore how LPS activity changes under greenhouse warming and Stratospheric Aerosol Intervention (SAI) using simulations from the fully coupled CESM2.1.3 ...
