Near-real-time two-dimensional wave spectrum retrieval from Gaofen-3 wave mode imagettes

International Conference on Environmental Remote Sensing and Geographic Information Technology
Near-real-time ocean monitoring using synthetic aperture radar (SAR) satellites aims to rapidly characterize the sea states from SAR data. Although recent studies have demonstrated near-real-time retrieval of significant wave height and mean wave period,

Sea Surface Wind Speed Retrieval with a Dual-Branch Feature-Fusion Network Using GaoFen-3 Series SAR Data

Remote Sensing
To address the suboptimal radiometric calibration accuracy observed in specific beam codes of the GaoFen-3 (GF-3) series satellite for sea surface wind speed (SSWS) retrieval, this study introduces a calibration constant correction method based on the ...

Mapping wave mechanisms in Gaofen-3 imagery at low incidence angles

Remote Sensing Letters
The novelty of this letter lies in preliminarily analysis of the wave mapping mechanism using Gaofen-3 (GF-3) acquired in extended wide (EW) mode at low incidence angle of 10–20°. In total, 35 Chinese GF-3 images in vertical-vertical (VV) were collocated
