摘要
舰载机着舰是对海上飞行要求极高的作业．对舰船未来时刻的运动姿态进行预报，可以避免舰载机同飞行甲板的剧烈碰撞，保证舰载机在有风浪的海上安全起降．本文根据船舶运动特点，分析了船舶在海上航行时的运动过程．利用船舶运动的测量数据和艏前波值运用时间序列分析方法建立了船舶运动的数学模型并给出运动姿态的预报值．
Landing aircraft on board carriers is a most delicate phase of flight operation at sea.Predicting the aircraft carrier's motion over an interval of several seconds within reasonable error bounds may allow the improvement in touch-down dispersion and increase the safety.In this paper characteristics of ship and ship's motion course in the case of moving at sea are analyzed.The ship's motion model is designed on the time series analysis of ARMA model.This method makes use of the measured data of pitch and waves in front of the ship and gives the predicted value of ship's attitude.This work indicates that the motion can be predicted well.
