Two effective machine learning-aided sea ice monitoring methods are investigated using 42 months of spaceborne Global Navigation Satellite System-Reflectometry (GNSS-R) data collected by the TechDemoSat-1 (TDS-1). The two-dimensional delay waveforms with different Doppler spread characteristics are applied to extract six features. which are combined to monitor sea ice using the decisi... https://www.ealisboa.com/flash-choice-Sten-Jacket-M-flash-find/
