摘要： 本文论述了全球导航卫星系统反射信号测量（GNSS-R）在海冰介电常数和海冰密集程度方面的潜在的研究价值，对欧洲空间局在格林兰岛迪斯科海岸采集的海冰数据进行分析，处理了两种反射信号的幅度的量化关系,同时跟踪多颗GNSS卫星并且保证了数据处理时间的连续性和有效性。根据双极化反射信号的幅度极化比和模拟海冰表面复介电常数得出结论, 幅度极化比和海冰表面的介电常数变化有联系。

关键词: GNSS反射信号, 海冰, 极化比, 介电常数

Abstract: This paper evaluates the potential use of reflected signals from Global Navigation Satellite Systems as a source of opportunity for sea ice permittivity and concentration research, analyses the sea ice data collected in the Greenland disco bay by the European space agency, processes the amplitudes between both polarizations of reflected signals, tracks several different satellites at the same time, and ensures the processing time and the effectiveness of the data. From the polarimetric ratio of Dual polarization of the reflected signals and the simulated complex dielectric constant, it concludes that the parametric ratio has an apparent evolution with the complex dielectric constant.

Key words: GNSS-R, sea ice, polarimetric ratio, permittivity
