作为飞机进近阶段最依赖的导航设备，仪表着陆系统对电磁环境的变化非常敏感。针对机场运行中最常见的场地保护区入侵问题和违规修建建筑物等情况，提出了下滑道受遮蔽物影响的快速计算方法。结合天线镜像理论和下滑信号空间合成原理，编写了仿真程序。对比实验表明，该快速计算方法能够实现定性分析，可以为机场管理机构和空中交通管理部门提供决策依据。

As the most dependent navigation equipment for airplane approaching ,instrument landing system is sensitive to the change of electromagnetic environment .Sensitive area in-trusion and illegal constructions are the most common violations in airport operation .To e-valuate these incidents ,a fast method to evaluate the tolerances of instrument landing system glide path with the shadow effect is proposed .Antenna image theory and glide path antenna array principles are chosen for the simulation program .Comparison test demonstrated that , the goal of qualitative analysis can be achieved by this fast evaluation method ,at the same time ,the simulation program can provide the basis for the airport authorities and air traffic management bureau .
