Abstract

Abstract

To detect the sea ice in small-scale fixed sea area, a shore-based sea ice detecting method is developed using GNSS reflected signal. Firstly, the method needs to calculate the intensity ratio of GNSS satellite reflected signal and direct signal, which is the ratio of the reflected signal correlation power and the direct signal correlation power. Then the sea ice thickness is obtained based on the empirical model. Preliminary analysis of the GNSS reflected signal collected during the sea ice experiment can obtain sea ice thickness which is 10~20 cm and shows good agreement between the GNSS-R sea ice thickness.
- GNSS satellite reflected signal,
- Sea ice thickness,
- Intensity ratio,
