摘要
菲涅尔光学助降系统(FLOLS)是典型的舰载机光学着舰引导系统。分析了影响FLOLS着舰引导精度的指示误差源和光学误差源,包括稳定平台跟踪误差、光源位置与理想着舰点位置偏差、光源温度、飞行员视觉误差,研究了FLOLS相关系统的工作原理和着舰引导误差的产生机理,建立了各误差源的数学模型。通过对FLOLS着舰过程进行重复仿真,使用标准偏差统计方法,得到各着舰引导误差的统计特性,进而得出各误差源影响着舰精度程度比较。
Fresnel lens optical landing system (FLOLS) is a typical optical landing system for contemporary aircraft carriers. Guide error sources and optical error sources impacting the precision of FLOLS, including platform tracking error, light source position and ideal landing position deviations, light source temperature and pilots visual analyzed. The working principle and mechanism of errors of related systems to FLOLS are studied also. Then set up mathematical models of each error source. By repeatedly landing process simulation and standard deviation statistical method, the statistical characteristics of each error are concluded. It makes a comparison among the impacts of each error source on landing accuracy. General conclusions about the terminal landing errors were given.
