A Method for Continues Calibration of a Rotating Antenna Scatterometer in Application to CFOSAT Measurements

IEEE International Geoscience and Remote Sensing Symposium, 2023
Spaceborne radar scatterometers require precise calibration to provide accurate sea surface wind speed retrievals. The Scatterometer (SCAT) onboard the China-France Oceanography Satellite (CFOSAT) presents additional calibration complexities as a ...

Data and processing of RFSCAT onboard CFOSAT

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
The Rotating fan-beam scatterometer (RFSCAT) onboard the Chinese-French Oceanography Satellite (CFOSAT) is a novel kind of scatterometer whose performance had been preliminarily verified by airborne campaign. In this paper the whole data processing chain that can achieve wind field derivation from original data set transmitted from the scatterometer ...

A Novel Partition Method Based on 2-D Ocean- Wave Spectra of CFOSAT SWIM

IEEE Sensors Journal, 2023
Two-dimensional wave spectra describe the distribution of wave energy in terms of frequency and direction. For unimodal seas (i.e., single peaked), wave spectra can describe the wave component accurately.

Comparison of Omnidirectional Ocean Wave Spectra From CFOSAT SWIM Observations and from Bouy Observations

IEEE International Geoscience and Remote Sensing Symposium, 2023
The Surface Waves Investigation and Monitoring (SWIM) omnidirectional wave spectra and its shape parameters are compared by matching the SWIM wave spectrum data with the buoy wave spectra of the National Data Buoy Center (NDBC). The results show that the

NWP Ocean Calibration for the CFOSAT Wind Scatterometer

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The unique rotating fan-beam feature of SCAT onboard CFOSA T leads to varying geometries across the swath and furthermore leads to varying wind retrieval performance across the swath. In order to improve the wind retrieval, two kinds of NWP Ocean Calibration (NOC) are applied. One is a NOC as a function of incidence angle (NOCinc).
