Classification of sea-ice concentration from ship-board S-band radar images using open-source machine learning tools [PDF]

Geoscientific Instrumentation, Methods and Data Systems
To gain context on the ambient sea ice field during the 2022 NASA Salinity and Stratification at the Sea Ice Edge (SASSIE) expedition we developed a machine learning model to predict sea ice cover classification from screen captures of a ship-board S ...

The dependence of radar target detectability on array weighting function [PDF]

, 2009
Presented at the IET-Radar 2007 Conference Edinburgh 15-18 October 2007This paper describes simulation work to assess the detectability of targets by an airborne fire control radar (FCR) operating in a medium pulse repetition frequency (PRF) mode in ...

A robust nonlinear scale space change detection approach for SAR images [PDF]

, 2013
In this paper, we propose a change detection approach based on nonlinear scale space analysis of change images for robust detection of various changes incurred by natural phenomena and/or human activities in Synthetic Aperture Radar (SAR) images using ...

Beyond Manoeuvre Theory for European Defence

Global Policy, EarlyView.
ABSTRACT This article contributes to the debate about European defence in the light of the Russo‐Ukraine war and growing doubts about US commitment to Europe. It argues that Europeans need to fundamentally relearn the ability to imagine military strategy from a European viewpoint.

Temporal stability of soil moisture and radar backscatter observed by the advanced Synthetic Aperture Radar (ASAR) [PDF]

, 2008
The high spatio-temporal variability of soil moisture is the result of atmospheric forcing and redistribution processes related to terrain, soil, and vegetation characteristics.

Future of edge AI in biodiversity monitoring

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecological decisions are slowed by the gap between collecting and analysing biodiversity information. Edge computing moves data processing closer to the sensor, with edge artificial intelligence (AI) using AI models for data processing and selective data transfer.

Ship Classification and Detection Based on CNN Using GF-3 SAR Images

Remote Sensing, 2018
Ocean surveillance via high-resolution Synthetic Aperture Radar (SAR) imageries has been a hot issue because SAR is able to work in all-day and all-weather conditions.

On the remote sensing of oceanic and atmospheric convection in the Greenland Sea by synthetic aperture radar

, 2004
In this paper we discuss characteristic properties of radar signatures of oceanic and atmospheric convection features in the Greenland Sea. If the water surface is clean (no surface films or ice coverage), oceanic and atmospheric features can become ...

UNIQAT: An open‐source toolkit for reproducible image quality assessment in marine surveys

Methods in Ecology and Evolution, EarlyView.
Abstract Modern marine surveys generate tens of thousands of underwater images per expedition, yet many are unusable due to image quality deterioration. Manual quality screening is labour‐intensive, subjective and inconsistent across observers and teams, hindering reproducible science, creating large backlogs of unprocessed imagery, and limiting real ...
