Estimating semi-stationary sea states through wavelet-based adaptive segmentation of ship motions
Published in Ocean Engineering, 2026
本文针对传统波浪浮标类比(WBA)方法在演化海况中因“刚性平稳性假设”而引入的误差问题,提出一种基于小波的自适应分段算法,将波浪视为半平稳过程,并可从船舶运动数据中动态捕捉随时间变化的海况特征。数值仿真表明,该方法能够抑制在病态反演估计系统中易被放大的谱误差,从而显著提升实时监测的可靠性。
This study addresses the inaccuracies of traditional wave buoy analogy (WBA) methods caused by rigid stationary assumptions in evolving oceans. We propose a wavelet-based adaptive segmentation algorithm that treats waves as semi-stationary processes, dynamically capturing time-dependent variations in ship motion data. Simulations demonstrate that this approach significantly enhances the reliability of real-time monitoring by mitigating spectral errors that are otherwise amplified in ill-posed estimation systems.

This study presents the first dedicated spatiotemporal coverage path planning (CPP) framework for autonomous sailboats in inhomogeneous and time-varying oceans. By integrating topological morphological constraints with forecast-aware look-ahead planning, the method overcomes performance anisotropy and partial accessibility induced by dynamic flows. Simulations show that the framework generates efficient, feasible paths in complex marine environments where traditional strategies fail.
