摘要
基于Sentinel-1遥感数据,对合成孔径雷达(SAR)极化特征数据在海冰漂移检测中的应用进行了深入研究。研究了水平发射水平接收(HH)和水平发射垂直接收(HV)极化数据在海冰漂移检测中的差异,分析了两种极化数据的优劣,并发现由两种极化数据检测到的特征信息具有互补的特性。通过特征融合的方法,将由两种极化数据得到的特征信息有效地应用于海冰漂移检测中。实验结果表明,利用所提出的方法得到的海冰漂移矢量在空间分布和覆盖率方面均得到了提高。该方法能够有效地应用于海冰漂移检测。
Abstract
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.
