| 摘 要： | 传统的海冰检测手段都存在着受天气影响或实时检测成本太高的缺点,为了更实时有效的检测海冰,减轻海冰灾害对于我国的影响,并达到防灾减灾的目的,本文研究了GPS反射信号(GPS-R)技术检测海冰的可能性。通过对2013年2月下旬在中国天津渤海湾的岸基架设GPS信号接收机所接收的观测数据进行分析,使用不同特性的反射海域(几乎全为海水或是海冰)的数据进行比对分析,其结果显示极化比值(反射左旋信号与直射右旋信号的比值)能够明显反演海冰密集度。本文首次将GPS-R技术应用于国内自主设计的渤海海冰检测实验中。

| Abstract: | Traditional detection methods for sea ice are limited by the weather or the high cost of real-time detection. In order to achieve effective real-time detection of sea ice to prevent and mitigate the disaster,in this paper we have studied the possibility of using GPS reflected signals (GPS-R) technique to detect sea ice. We have analyzed the test data in February 2013,which is collected from the GPS signal receiver in the Bohai sea experiment in Tianjin of China. The result shows that the polarization ratio (the ratio of the direct RHCP signals and the reflected LHCP signals) could simulate sea ice concentration. This study is the first one among the domestic research to apply the GPS-R technology to the Bohai sea ice detection experiment. |
