Abstract: The motion of sea ice has a great effect on winter navigation, oil field exploration in the Bohai Sea, and it is very important to measure the ice drift accurately and efficiently. Radar imagery has been used for sea ice monitoring and forecasting. Combining with the radar imagery and Particle Image Velocimetry (PIV), full field measurement of sea ice drift around the platform can be obtained, which is specified in detail in this paper. The theory and implementation of cross-correlation in PIV are presented briefly in the paper, including the filtering method to modify the invalid vectors, and some motion maps by cross-correlation are provided. Furthermore, the comparison with traditional tracing method is conducted in the paper to show deeply the validity of the application of PIV.
