摘要
结合国内先进的航海雷达测冰技术,介绍了全场冰漂流测量技术的互相关分析原理及其Fouri er实现方法,以及冰漂流场中部分错误矢量的修正方法.利用全场冰漂流测量技术,通过对一些实测的雷达海冰图像进行互相关分析处理,获得的二维海冰漂流场的矢量分布图,充分验证了全场冰漂流测量技术的实用性和可靠性.
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.
