本文叙述了船舶运动艏前波法预报所做的研究工作。艏前波预报方法看来是解决船舶运动预报比较切实可行的方法，它是利用舰船本身的摇摆观测数据和舰船艏前海浪的观测数据，对舰船摇摆建模及预报。文中讨论了船舶在波浪中运动艏前波模型动态建模与预报方法，为了改善和提高预报的精度和可靠性，进行预报前，对实船试验所采集信号做实时在线预处理和滤波处理，同时进行参数辨识、定阶，然后进行拟合建模和预报，对多组实船试验的信号实时在线进行超前预报，并与自回归预报法和周期图预报法进行比较，获得了比较令人满意的结果，在提高预报精度、增加舰载机着规的安全性和扩大海况使用范围等方面，具有比较高的实用价值。
This paper describes the research work done by foreword wave forecast in ship movement. Pre-wave prediction method appears to be a more practical method to solve the forecast of ship motion. It uses the observation data of the ship’s own sway and the observation data of the wave before the ship to model and forecast the ship’s sway. In order to improve and improve the accuracy and reliability of prediction, before the prediction, the real-time on-line preprocessing and filtering of signals collected by real ship test are discussed in this paper. At the same time, the parameters are identified and ranked, and then the fitting modeling and forecasting are carried out. The real-time on-line forecasting of signals of multiple groups of real ships is carried out in advance and compared with the autoregressive forecasting method and the periodic pattern forecasting method, Satisfactory result is of high practical value in improving forecasting accuracy, increasing the safety of carrier-based aircraft regulations and expanding the use of sea conditions.
