Longitudinal Deck Motion Prediction and Compensation for Carrier Landing.

Longitudinal deck motion causes the variation of the height of ideal touch down point, which is a main factor affecting the safety of carrier landing. In order to decrease the influences of longitudinal deck motion on carrier landing, a method of deck motion prediction and compensation is proposed. Deck motion compensator based on lead network and deck motion predictor based on particle filter are designed. The deck motion signal is first processed by the predictor and compensator and then connected to the longitudinal automatic carrier landing system, which helps the carrier aircraft track the deck motion accurately in the final stage of landing and decreases the influences of deck motion on carrier landing. The designed compensator and predictor are examined and compared with other method through simulation experiments in different sea states. Simulation results show that the designed deck motion predictor and compensator can effectively compensate for the landing error caused by deck motion and can significantly improve the safety and accuracy of carrier landing.
