A new algorithm of aircraft carrier landing was studied utilizing airborne infrared camera/inertial integrated system, aiming to provide the guidance information and accomplish aircrafts semi-auto or auto landing. The mathematic relationship between guidance parameters and imaging information was modeled, and the relative position and attitude information between the carrier and the aircraft were estimated through least square method. Then the pitch, roll and heave movement of the carrier were compensated, so the touchdown point could be predicted in order to guide aircraft landing. Based on the theoretical research, the field verification tests were carried out, which adopted the minification scheme to simulate the process of aircraft carrier landing. In the experiments, the runway simulator simulated the motion of the carrier deck and the land vehicle was used as the aircraft. The results verify that the landing guidance system scheme is feasible and effective, and lays the technical foundation for the flight test and improves its safety.
