The Study on Ocean Ice Intensity Surveyed by GNSS-R Signal on the Coast

Intensity and thickness of sea ice are the basic parameters of ocean ice disaster monitoring. Compared with other detection methods, GNSS-R with high spatial and temporal resolution, lower cost, abundant sources, etc. has huge potential. Based on electromagnetic theory, the principle of GNSS-R inversion technology of sea ice intensity and thickness will be systematically studied on. Then the experiment of surveying ice thickness and intensity by GNSS-R was performed at Bohai Gulf in Tianjin of China from 17 to 18 in January 2014 in order to study the relation between the polarization ratio (between direct and reflected signal) and ice intensity. The result of the experiment has shown that the relation between polarization ratio and ice intensity is existent.
