Processing of the CFOSAT-SWIM data: Algorithm prototyping and simulations [PDF]

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
This paper presents the under-going development of the ground segment algorithms of the SWIM instrument. SWIM is a wave scatterometer which will be embarked on the Chinese French oceanography mission, CFOSAT. SWIM aims at measuring the 2D oceanic wave spectra; it is a Ku band real aperture radar.

Validation of Multisource Altimeter SWH Measurements for Climate Data Analysis in China’s Offshore Waters

Remote Sensing
Climate data derived from long-term, multisource altimeter significant wave height (SWH) measurements are more valuable than those obtained from a single altimeter source.

Multidecadal Oscillation Masks Ocean Wave Climate Trends in 75‐Year Global Wave Hindcast

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The observed increases in temperature and sea level are clearly driven by climate change, and these trends are projected to accelerate in the future. The ocean surface wave characteristics are projected to change depending on the climatic elements.

CFOSAT: Latest Improvements in the Swim Products and Contributions in Oceanography

IGARSS 2022 - 2022 IEEE International Geoscience and Remote Sensing Symposium, 2022
For the first time, co-located wind vectors and wave spectral characteristics are available thanks to the French/Chinese CFOSAT mission, which includes a wind scatterometer SCAT and a wave scatterometer SWIM. Three years after its launch, CFOSAT data is thoroughly qualified and various scientific work has been undertaken.

Overview of SWALIS, KaRADOC and HOMARDS: A Suite of Airborne Radars to Support Satellite Earth Observation Missions. SWOT Calibration/Validation Campaign in South Rhine

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
The figure provides an overview of the uncalibrated NRCS measurements taken above the La Chèze water storage. The path is visible on an satellite map as traces showing higher reflected power (brighter areas) compared to the surrounding ground. ABSTRACT This paper presents the different airborne radar systems which are developed at IETR (Institut d ...

Detailed Monitoring of the Antarctic Marginal Ice Zone by Satellite Radar Altimeter Synergy—A Study of the Weddell Sea/Indian Ocean Sector in July 2017

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The wave‐affected Marginal Ice Zones (MIZ) is a key region of air‐ice‐ocean interactions in the Southern Ocean (SO). However, challenges still remain for the large‐scale observation of the MIZ. In this study, we use four concurrent radar altimeters to retrieve the wave‐affected MIZ in the eastern Weddell Sea‐Indian Ocean sector, which was ...
