The remote sensing data obtained from the Sentinel-1 spacecraft allows the application of the synthetic aperture radar (SAR) polarization feature data to the detection of the sea-ice drift. The difference in the usage of the horizontal-horizontal (HH) and horizontal-vertical (HV) polarization data for the detection of the sea-ice drift is discussed in terms of their advantages and disadvantages. The information detected using these two kinds of polarization data is observed to be complementary. Using feature fusion, the feature information detected using these two kinds of polarization data can be used for monitoring the sea-ice drift. The experimental results indicate that the sea-ice drift vector obtained using the proposed method is improved in terms of the spatial distribution and coverage rate, suggesting that the proposed method can be effectively applied for monitoring the sea-ice drift.
