摘要

Instrument Landing System (ILS) is a radio beam transmitter that provides both lateral and vertical guidance for approaching aircraft. The multipath effect resulting from the structure roughness causes problem of the Localizer type Directional Aid (LDA) installed at Matsu Beigan Airport, Taiwan. Flight inspection showed that the course structure couldn't comply with the C AT I standard. This problem could seriously threat to flight safety in approach to landing. This paper aims at the main reflector to cause the multipath effect of signal in space using the ILS performance simulator with real measurement data. This numerical way not only calculates the course structure in a short period of time, but also save the vast cost from flight inspection. The Navigational Aid Performance Prediction Model (NPPM) from Avionic Engineering Center of Ohio University is adopted for predicting the performance of the localizer in this paper. After a series of simulation and analysis, the main reflector of the multipath effect has been pointed out. Several solutions to solve the problems of Beigan Airport 03 LDA are proposed and discussed from this study.
