摘要
研究了海冰的介电常数和极化特性,对GNSS-R观测数据进行处理,计算反射信号左右旋极化分量的比值,可以看出,GNSS-R信号极化比值的变化与海冰密集度观测数据是比较一致的。研究结果初步表明,GNSS-R技术可以作为海冰探测的新手段。
The paper studied the permittivity and the polarization properties of the sea ice,and then processed the GNSS-R observing data sets,and calculated the polarimetric ratio between the RHCP and the LHCP components. It can be seen that the proposed method was more consistent with the data of sea ice concentration. The preliminary experimental results showed that the GNSS-R is a new way for sea ice detection.
