| Abstract: | According to digital signal analysis, the paper provides an applying method for measuring the ice velocity distribution in large scope sea area of Liaodong Gulf in time by Radar. Through processing two successive images, it can be found that the peaks of cross-correlation function,due to apply the DPIV technique and VC programming,the deficiency of the ice velocity got by Radar, which is only one point, has been solved. |
