【Abstract】 Combining with radar technology, the fundamentals of the full field measurement based on cross correlation and Fourier transform are specified in this paper. Thus a two-dimensional distribution map of ice moving is obtained. A filtering method of invalid vectors correction is presented. To show deeply the validity of the present methods, ice-moving maps obtained from the radar images grabbed in Liaodong Gulf are provided in this paper.更多还原
