Abstract : To predict reflection/interference zones for scanning beam Instrument Landing Systems, representative situations for an airport environment were selected in developing multipath models. Interfering signals reflected from a large building near a runway will usually be confined to well defined specular regions. The interfering reflecting signal magnitude in these regions can be large. The report presents these regions of interfering reflections in graphic form for various reflecting surface orientations and lateral distances between the radiating source and the reflecting surface.
