Range-ambiguous Clutter Suppression for Forward-looking Frequency Diverse Array Space-time Adaptive Processing Radar

Leida xuebao, 2015
In a high pulse-repetitive-frequency forward-looking radar, the clutter echo is not only severely rangedependent but also range-ambiguous. It is therefore difficult to realize clutter compensation and suppression for conventional Space-Time Adaptive ...

Doppler-Spread Clutter Suppression in Single-Channel Noise Radar

, 2022
S.881-883Continuous emission noise radars suffer from the problem of reduced sensitivity due to masking effects caused by the side-lobes of direct signal leakage, clutter returns and echoes of close targets.

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

A Weather Radar Ground Clutter Suppression Method Using Adaptive Coherent Pulse Integration

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Ground clutter poses a significant challenge to the accuracy of weather radar products, especially for aeroecology monitoring. Operational weather radar commonly employs a fixed coherent pulse integration (CPI) for clutter suppression.

Making Flood Inundation Mapping (FIM) Work for Multiple Users: Improving the Design of FIM for Decision Support

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Visualizing and communicating flood inundation depth and extent can be valuable for informing decisions related to flood preparedness and disaster response. In the United States, several different types of flood inundation mapping (FIM) exist and a new National Water Model (NWM) FIM product is being rolled out across the country (expected to ...

Anomalous Sea Ice Retreat in the Refreezing Western Arctic by a 30‐Year Record Cyclone in October: Oceanic, Atmospheric, and Wave Influences

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An extreme Arctic cyclone (AC) in October 2022 reached a record‐low pressure of 955 hPa and caused unusual wave‐induced sea‐ice breakup in the Canada Basin, making it the strongest event in the western Arctic in 30 years. Here we examine how this event interrupted freeze‐up by quantifying sea‐ice retreat associated with atmospheric and oceanic
