Interference Predictions for VHF/UHF Air Navigation Aids (Supplement to IER-26-ITSA 26 and ERL 138-ITS 95).

Abstract

The report supplements information previously developed on interference predictions for VHF/UHF air navigation aids. Included are (a) radiation patterns needed to adapt curves previously developed for the Instrument Landing System (ILS) Localizer and Tactical Air Navigation (TACAN) to new equipment types, (b) comparisons of the propagation models used for predictions made from 1962 to the present, (c) propagation information in a different form, i.e. attenuation greater than free space for Distance Measuring Equipment (DME), TACAN and VHF Omnirange (VOR), (d) DME, for equipment configurations not previously considered, and (e) an errata list for earlier ESSA Technical Reports.
