Abstract:

In this study, an improved periodic graph method was proposed for wave power spectrum analysis, optimizing the computational process of spectrum estimation and enhancing the inversion speed of parameters such as wave height and wave period. An algorithm for estimating wave direction was investigated. The surface slope was derived from the heights of three points on the wave surface measured by the radar array, and the wave direction information was determined through the interrelationship between the slope and the heave motion of the water surface, simplifying the computational approach for wave direction inversion. Experimental results of comparison with buoy data demonstrate that the correlation of wave parameters obtained by the inversion method presented in this paper and the Datawell Mk III wave buoy reaches 98.4%, suiting real-world applications.

摘要:

提出了一种改进周期图法的波浪功率谱分析方法,优化了谱估计的计算流程,提升了波高波周期等参数反演的速度。研究了波浪方向估计算法,利用雷达阵列测得的波面三点高度获取水面斜率,通过斜率及水面升沉变化的相互关系来确定波浪方向信息,简化了波浪方向反演的计算方法。与浮标数据对比实验结果表明,波浪参数反演方法与Datawell Mk III波浪浮标的反演方法得到的波浪参数相关性达到98.4%,可以满足实际使用要求。
