Abstract

The aircraft instrument landing system (ILS), operating in the VHF/UHF frequency bands has been in operation for over 50 years. With the various glide slope systems and the highly directional localizer antenna arrays successful ILS performance can now be achieved under the most adverse electromagnetic conditions. Several disadvantages prevent ILS from meeting the needs of aviation indefinitely. These disadvantages are discussed, and a microwave landing system is described.<>

美国飞机着陆系统- vhf - uhf和微波

在VHF/UHF频段工作的飞机仪表着陆系统(ILS)已经运行了50多年。利用各种滑坡系统和高度定向定位器天线阵列，现在可以在最不利的电磁条件下实现成功的盲降性能。一些缺点阻碍了盲降系统无限期地满足航空的需要。讨论了这些缺点，并介绍了一种微波着陆系统。
