Abstract

From the announcement which sees discusses about the spatial modulation which is a basic principle of the induction signal which the instrument landing system provides to the aircraft with instrument landing system, depth made be and became the help which makes understand and character did. Explained the fundamental notions of spatial modulation with precedence, the signal which space is modulated with this together influenced to the aircraft receiver and the azimuth and angle of glide were indicated and until with the principle of operation of the aircraft receiver and the process which is general DDM(difference in depth of modulation) and they related they explained.

본 발표문에서는 게기착륙시스템이 항공기에 제공하는 유도신호의 기본원리인 공간변조에 대해서 논의함으로써 계기착륙시스템을 심도있게 이해하는데 도움이 되고자 하였다. 우선적으로 공간변조의 기본개념을 설명하였으며, 이와 함께 공간 변조된 신호가 항공기 수신기에 영향을 주어 방위각 및 활공각이 표시되기까지 전반적인 과정을 DDM(difference in depth of modulation) 및 항공기 수신기의 동작원리와 관련시켜 설명하였다.
