摘　　要：提出了一种基于红外探测的机载光电/惯性组合着舰导引新方案,综合机载红外热像仪和惯导信息实现舰、机运动分离,完成舰载机半自动或自动着舰导引,具有精度高、自主性好、不易受电磁干扰的优点。阐述了系统方案,并深入研究了靶标规则摆放情况下的着舰导引算法,给出了计算机仿真结果。仿真结果表明,舰机相对航向角估计误差小于10′、着舰位置估计误差小于1 m,验证了方案的可行性及算法的有效性,具有较高的工程应用价值。A novel scheme of aircraft carrier landing is proposed employing airborne infrared electro-optical/inertial integrated navigation,which can provide the relative position and attitude information of the carrier and the aircraft to implement aircraft semi-auto or auto landing.The presented scheme has the advantages of high accuracy,self-contained and anti-jamming.This paper illustrates the principle of the system,studies the algorithm of cooperative targets in the case of regular layout and provides computer simulation results.Simulation results show that estimation error of the relative yaw of the aircraft is less than 10′ and estimation errors of aircraft landing position are within 1m,which indicate the feasibility of the scheme and the efficiency of this algorithm.Hence the scheme proposed in this paper is of great value in engineering practice.
