摘要
基于数字信号分析原理,对连续两幅图像进行互相关分析,寻找互相关函数的峰值;应用数字粒子图像测速(digitalparticle image velocimetry)技术,并通过计算机VC编程,解决了用于雷达测量单点流冰速度的不足;为大范围区域内流冰场瞬时速度的计算,实时雷达测量辽东湾海上流冰速度场提供了有应用价值的方法。
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.
