Development and Test of Low Impact Resistance Structures. Volume II. Interference of Low Impact Resistance Structures with Instrument Landing System (ILS) Signals.

Abstract

Scattering of radiation by the ALS light supports in front of the Course Antenna will not result in course errors. There are three reasons for this conclusion: (1) The forward scattering from the poles is weak. (2) Each pole is so close to the center line that no detectable phase change could be noted by an incoming plane. (3) The symmetric arrangement of poles cancels out any asymmetrical affect of one pole. (Modified author abstract)
