Improved the Impact of SST for HY-2A Scatterometer Measurements by Using Neural Network Model [PDF]

open access: yesSensors, 2023
The variation of sea surface temperature (SST) can change the backscatter coefficient measured by a scatterometer, resulting in a decrease in the accuracy of the sea surface wind measurement.

Back-Projected Signal-Based Self-Interferometric Phase Analysis Technique for Sea Surface Observation Using a Single Scatterometer System [PDF]

open access: yesSensors, 2023
This manuscript presents a self-interferometric phase analysis technique for sea surface observation using a single scatterometer system. The self-interferometric phase is proposed to complement the imprecise analysis results due to the very meager ...

Polar Applications of Spaceborne Scatterometers. [PDF]

open access: yesIEEE J Sel Top Appl Earth Obs Remote Sens, 2017
Wind scatterometers were originally developed for observation of near-surface winds over the ocean. They retrieve wind indirectly by measuring the normalized radar cross section (σo ) of the surface, and estimating the wind via a geophysical model function relating σo to the vector wind.

High Wind Geophysical Model Function Modeling for the HY-2A Scatterometer Using Neural Network

open access: yesRemote Sensing, 2022
Under low to medium wind speeds and no rainfall, the retrieved vector wind from a scatterometer is accurate and reliable. However, under high wind conditions, the currently used geophysical model function (GMF), such as NSCAT-2, for wind vector retrieval
