Abstract
This paper presents a FLIR/INS/RA integrated landing guidance method to provide information of aircraft states and carrier dynamics for fixed-wing aircraft landing on the aircraft carrier in low-visibility weather and high sea states. The method utilizes the Forward-Looking Infrared (FLIR) system, the Inertial Navigation System (INS), and the Radio Altimeter (RA) as sensors, to track infrared cooperated targets on the aircraft carrier. Several algorithms like the Newton iterative algorithm, the Kalman Filter (KF), and the Wavelet Transform (WT) are employed to compute real-time and high-precision estimates of the aircraft states (runway-related position, attitude, and velocity) and the carrier dynamics (pitch, roll, and heave). A simulation experiment is conducted and shows satisfactory results for the aircraft carrier landing guidance.

Summary
The landing guidance information is extremely useful for fixed-wing aircraft landing on the aircraft carrier. For the safe landing operation, the landing guidance system should provide accurate aircraft states (e.g., position, velocity, and attitude) and the carrier dynamics’ (e.g., pitch, roll, and heave) information for the aircraft to plan an optimal descent trajectory and employ a corresponding control strategy [3, 4, 5] in all weather and sea states. Laurent [8] presents a method for carrier landing by using aircraft optical sensors and visual features Those systems can provide satisfactory landing guidance information in normal weather and sea states. For the purpose of implementing the aircraft landing on the carrier safely and accurately in low-visibility weather, high sea states and an electromagnetic interference environ‐ ment, an independent and autonomous landing guidance system integrating measurements of FLIR system, INS, and RA is presented in this paper.
