纵向甲板运动主要造成理想着舰点高度的变化，给着舰过程增加了难度，同时也严重威胁了舰载机着舰的安全性。为了减小由甲板运动引起的着舰误差，基于超前网络设计了甲板运动补偿器，并通过卡尔曼最优预估理论设计了甲板运动预估器，将甲板运动通过预估器和补偿器后加入纵向自动着舰导引系统中，实现了舰载机着舰末端过程甲板运动的补偿。仿真结果表明，设计的甲板运动预估器与补偿器可以有效地补偿由于纵向自动着舰导引系统在有效频率段内存在的相位迟后所引起的着舰误差，提高了舰载机着舰的安全性。

Longitudinal deck motion may cause height changing of the ideal touch-down point in carrier landing,which make it difficult for landing and may seriously affect the safety of aircrafts during the landing.To reduce the landing error caused by the deck motion,a deck motion compensator was designed based on lead network,and a deck motion predictor was designed based on Kalman optimal estimation.The motion of deck was integrated into the automatic landing guidance system through the predictor and compensator for compensating the deck motion in the last period of the course of carrier landing.The simulation results show that the designed deck motion predictor and compensator can effectively compensate the longitudinal error caused by phase delay of automatic carrier landing system,and improves the landing safety of carrier landing aircrafts.
