一些海上作业可以受益于短期确定性海浪预测(DSWP)。传统的X波段雷达最近已被证明是一个低成本的方便来源的二维波剖面信息DSWP的目的。然而,这样的旋转雷达通常将时间拖尾引入到数据中,这在使用传统的基于傅立叶变换的波浪预测方法时引入误差。作者报告了一种新的DSWP方法,可以避免此类错误。此外,它不容易受到任何形式的直接或间接基于反演的方法所产生的条件数问题的影响。进行了广泛的数值分析,以说明DSWP和所提出的技术来处理它的效率的数据的混合时空性质的影响。
A number of maritime operations can benefit from a short-term deterministic sea wave prediction (DSWP). Conventional X-band radars have recently been shown to provide a low-cost convenient source of two-dimensional wave profile information for DSWP purposes. However, such rotating radars typically introduce temporal smearing into the data, which introduces errors when traditional Fourier transform–based wave prediction methods are used. The authors report on a new approach for DSWP that avoids such errors. Furthermore, it is not susceptible to the condition number problems that arise with any form of direct or indirect inversion-based approaches. Extensive numerical analyses are conducted to illustrate the effect of the mixed space–time nature of the data on DSWP and the efficiency of the proposed technique to handle it.
