Direct Ocean Surface Velocity Measurement for Chinese Gaofen-3 SAR Satellite [PDF]

2020 17th European Radar Conference (EuRAD), 2021
Spaceborne Synthetic Aperture Radar (SAR) is one important way to obtain the information of ocean surface velocity. The Doppler Centroid Anomaly (DCA) estimation, which obtain the radical velocity based on the difference between the measured Doppler centroid and the predicted Doppler centroid, have be used to most onboard spaceborne SAR. GaoFen-3 (GF-3)
