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GN S S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幅度极化比和海冰表面的介电常数变化之间的联系。%This paper evaluates the potential use of reflected signals from Global Navigation Satellite Systems for sea ice permittivity and concentration research.We analyzed sea ice data collected from Disko Bay,Greenland by the Eu-ropean Space Agency,processed the amplitudes between both polarizations of the reflected signals,tracked several different satellites at the same time,and calculated the processing time and the effectiveness of the data.We con-clude from the polarimetric ratio of dual polarization of the reflected signals and the simulated complex dielectric constant that the parametric ratio has an apparent evolution with the complex dielectric constant.
