| 摘 要： | 机场积雪会造成仪表着陆系统信号畸变,影响着陆安全,在分析仪表着陆系统下滑道形成原理的基础上,根据几何光学理论建立机场积雪覆盖模型,并依据经验问题的抽象模型,通过仿真分析两类典型的地面积雪覆盖情况下仪表着陆系统下滑道性能的变化。

| Abstract: | Snow cover on airport will bring distortion to the ILS signal,leading to safety problem to aircraft landing.The principle of ILS glide slope system is firstly outlined.Snow cover model for the airport is then established based on geometrical optics.Simulation is performed to analyze the performance of ILS glide slope under two types of snow cover conditions. |
