Abstract

This paper explains how existing electrical ADU(Antenna Distribution Unit) has been improved into a mechanical ADU. Generally the mechanical ADU has stabilized Glide Path which provides a RF signal to the aircraft for safe landing and it has solved the issue of phase shift and power distribution ratio change which can be occurred during long-term use. Besides it has been certified by Flight check and operating several airports in oversea as well as in korea.

본 논문에서는 기존 전자식 안테나분배장치(ADU)를 기계식 ADU로 개선한 사항을 설명한다. 기계식 ADU는 항공기가 착륙할 수 있도록 전파신호를 제공하는 활공각제공시설(Glide Path)의 신호를 안정화시켰으며, 장기간 사용 시 발생할 수 있는 위상변화 및 파워분배비율 변화의 문제점을 해결하였다. 그리고 개선된 ADU는 비행검사를 통해 안정성을 검증하였으며 현재 국내 외 공항에 설치되어 운영중이다.
