The impact of deck motion on the complete automatic landing success rate is taken into account during the landing procedure. Aiming at the asynchrony of the deck and the longitudinal height of the carrier-based aircraft caused by the delay in the response of the carrier-based aircraft, the deck motion prediction technology is used to forecast the motion parameters of the ship in the effective time in the future. A six-degree-of-freedom deck motion model based on sine wave combination is established, and a deck motion prediction model is established based on a back-propagation (BP) artificial neural network. A deck motion compensation model is developed in accordance with the advance network, and the landing guidance system is integrated to guarantee that the vector of the deck and the carrier aircraft are in synchronization. The aircraft motion model is established, and the feasibility of the deck motion prediction and compensation technology is verified through the simulation experiments.
